A quien diseñe su baño para la Luna ... La Agencia Espacial Estadounidense busca ideas para un dispositivo que sea más pequeño, más eficiente y capaz de funcionar tanto en micro-gravedad como en gravedad lunar ...
La NASA ha lanzado un concurso para elegir el diseño del baño de su próxima misión lunar, prevista para 2024 en el marco de su programa Artemis.
La agencia espacial estadounidense publicó las reglas del concurso en HeroX, una plataforma donde las organizaciones pueden usar el crowdsourcing (colaboración abierta distribuida) para encontrar soluciones innovadoras.
Aunque la Estación Espacial Internacional ya cuenta con baños especiales para los astronautas, la nueva misión tripulada a la Luna requeriría de un diseño especial para que pueda funcionar en la gravedad lunar, que es aproximadamente una sexta parte de gravedad de la Tierra.
En particular, la NASA busca ideas para un dispositivo de próxima generación que sea más pequeño, más eficiente ycapaz de funcionar tanto en micro-gravedad como en gravedad lunar. Por medio del concurso, la agencia aspira a encontrar nuevos diseños que puedan reducir la masa de los baños de última generación a más de la mitad, de 54 a 31 kilos, reduciendo su volumen en un 70 %, desde 0,17 a 0,12 metros cúbicos. El inodoro estándar de una casa pesa 30-60 kilos, pero la complejidad de operar en entornos de gravedad reducida requiere más componentes para un inodoro espacial, recuerda la NASA.

What is BurpSuite? Burp Suite is a Java based Web Penetration Testing framework. It has become an industry standard suite of tools used by information security professionals. Burp Suite helps you identify vulnerabilities and verify attack vectors that are affecting web applications. Because of its popularity and breadth as well as depth of features, we have created this useful page as a collection of Burp Suite knowledge and information.
In its simplest form, Burp Suite can be classified as an Interception Proxy. While browsing their target application, a penetration tester can configure their internet browser to route traffic through the Burp Suite proxy server. Burp Suite then acts as a (sort of) Man In The Middle by capturing and analyzing each request to and from the target web application so that they can be analyzed.
Everyone has their favorite security tools, but when it comes to mobile and web applications I've always found myself looking BurpSuite . It always seems to have everything I need and for folks just getting started with web application testing it can be a challenge putting all of the pieces together. I'm just going to go through the installation to paint a good picture of how to get it up quickly.
BurpSuite is freely available with everything you need to get started and when you're ready to cut the leash, the professional version has some handy tools that can make the whole process a little bit easier. I'll also go through how to install FoxyProxy which makes it much easier to change your proxy setup, but we'll get into that a little later.
Requirements and assumptions:
Mozilla Firefox 3.1 or Later Knowledge of Firefox Add-ons and installation The Java Runtime Environment installed
Download BurpSuite from http://portswigger.net/burp/download.htmland make a note of where you save it.
on for Firefox from https://addons.mozilla.org/en-US/firefox/addon/foxyproxy-standard/
If this is your first time running the JAR file, it may take a minute or two to load, so be patient and wait.
Video for setup and installation.
You need to install compatible version of java , So that you can run BurpSuite.
This is a post about an old vulnerability that I finally found the time to blog about. It dates back to 2014, but from a technical point of view it is nevertheless interesting: An XML parser that tries to fix structural errors in a document caused a DoS problem.
All previous posts of this series focused on XSS. This time, we present a vulnerability which is connected another Cloud Management Platform: OpenNebula. This Infrastructure-as-a-Service platform started as a research project in 2005. It is used by information technology companies like IBM, Dell and Akamai as well as academic institutions and the European Space Administrations (ESA). By relying on standard Linux tools as far as possible, OpenNebula reaches a high level of customizability and flexibility in hypervisors, storage systems, and network infrastructures. OpenNebula is distributed using the Apache-2 license.
OpenNebula offers a broad variety of interfaces to control a cloud. This post focuses on Sunstone, OpenNebula's web interface (see Figure 1).
Figure 1: OpenNebula's Sunstone Interface displaying a VM's control interface
Before OpenNebula 4.6.2, Sunstone had no Cross-Site Request Forgery (CSRF) protection. This is a severe problem. Consider an attacker who lures a victim into clicking on a malicious link while being logged in at a private cloud. This enables the attacker to send arbitrary requests to the private cloud through the victims browser. However, we could find other bugs in OpenNebula that allowed us to perform much more sophisticated attacks.
Denial-of-Service on OpenNebula-VM
At its backend, OpenNebula manages VMs with XML documents. A sample for such an XML document looks like this:
OpenNebula 4.6.1 contains a bug in the sanitization of input for these XML documents: Whenever a VM's name contains an opening XML tag (but no corresponding closing one), an XML generator at the backend automatically inserts the corresponding closing tag to ensure well-formedness of the resulting document. However, the generator outputs an XML document that does not comply with the XML schema OpenNebula expects. The listing below shows the structure that is created after renaming the VM to 'My <x> VM':
The generator closes the <x> tag, but not the <NAME> tag. At the end of the document, the generator closes all opened tags including <NAME>.
OpenNebula saves the incorrectly generated XML document in a database. The next time the OpenNebula core retrieves information about that particular VM from the database the XML parser is mixed up and runs into an error because it only expects a string as name, not an XML tree. As a result, Sunstone cannot be used to control the VM anymore. The Denial-of-Service attack can only be reverted from the command line interface of OpenNebula.
This bug can be triggered by a CSRF-attack, which means that it is a valid attack against a private cloud: By luring a victim onto a maliciously crafted website while logged in into Sunstone, an attacker can make all the victim's VMs uncontrollable via Sunstone. A video of the attack can be seen here:
This quick blog post will document getting started with developing Burp extensions using java. Burp provides interfaces for developers to hook into the Burp application and extend the application or integrate with other tools, this interface is documented on the following site - http://portswigger.net/burp/extender/
After downloading and opening up Eclipse you will need to create a new java project. This can be done by clicking "File->New Java Project". Fill in a project name and click finish.
Once the project has been created you will need to create a new package called "burp". This can be done by right clicking the "src" folder under your new project and selecting "New->Package". When the dialog comes up set the "Name" as "burp":
You should now have a package named "burp" under the source folder in the right pane. Now you will need to import the Burp extender classes into your project. Download all of the extender classes to a local folder, once this is done right click on the "burp" package in your project and select "Import". On the dialog window that comes up select "General->File System" and hit "next":
On the next dialog you will need to navigate to where you downloaded the Burp extender classes to. Once you have done this you should see the classes, click on the folder to select all items and click "Finish":
Next we can add the Burp application into the project. To do this click on "Project->Properties" on the top toolbar. When the dialog opens select "Java Build Path" and then the "Libraries" tab. On this dialog click "Add External JARs..."
Navigate to where ever you have Burp downloaded to and select it. After you have done this click "OK" to dismiss the dialog. You are now ready to build your own Burp extensions. You can test your environment by creating a new class in the burp package named "BurpExtender". Right click the "burp" package and click "New->Class". On the dialog that comes up enter "BurpExtender" and click "Finish":
In the "BurpExtender" class you can enter the following:
package burp;
public class BurpExtender { public void registerExtenderCallbacks(IBurpExtenderCallbacks callbacks) { callbacks.registerMenuItem("Hello World.", new CustomMenuItem()); } }
class CustomMenuItem implements IMenuItemHandler { public void menuItemClicked(String menuItemCaption, IHttpRequestResponse[] messageInfo) { try { System.out.println("Hello From Burp!"); System.out.println("Request Item Details"); System.out.println("Host: " + messageInfo[0].getHost()); System.out.println("URL: " + messageInfo[0].getUrl());
After adding the content to your "BurpExtender" class you are ready to run the project for the first time. Click on "Run->Run" from the menu. You should see the following dialog asking how it should run your project:
Select "Java Application" and click "Ok". Next you should receive a dialog asking which application you want to run. Select "StartBurp - burp" and click "Ok":
You should now see the burp application running. Intercept a request in the application and right click on the request, you should now see an item in the menu named "Hello World."
When you click the "Hello World." menu button you should see some information about the request in your eclipse console window:
That's it, you now have setup your working development environment for building your own Burp extensions. The javadocs for the Burp Extender interfaces are available on the Extender web page:
o_O, he repasado caracter a caracter y son visualmente iguales, si mirais en un editor hexa vereis que realmente no lo son, lógicamente no se trata de un expedienteX.
La cuestion es que según la fuente que tengais, debajo de la comilla o debajo del ] hay un punto microscópico :)
Esto es como cuando me emparanoie de que gmail cuando llevas un rato escribiendo un email y se hace auto-save, aparece una especie de acento raro en la pantalla :)
En estos casos, la metodología tipica de copypastear un trozo de la primera sentencia con el resto de la segunda sentencia, te lleva a los 2 caracteres que varían, pero no aprecias (segun la fuente que tengas) la diferéncia.
Son dígitos unicode, sabe Dios de que pais, y sabe Dios también como los escribí con mi teclado, se me ocurren bromas de código fuente que se pueden hacer con esto :D, pero vamos, si tenemos metodología de reaccién ante expedientesX, sobretodo aquello de divide y vencerás dicotómico, en pocos minutos se resuelven este tipo de problemas.
Modern gcc compiler (v9.2.0) protects the stack by default and you will notice it because instead of SIGSEGV on stack overflow you will get a SIGABRT, but it also generates coredumps.
In this case the compiler adds the variable local_10. This variable helds a canary value that is checked at the end of the function. The memset overflows the four bytes stack variable and modifies the canary value.
The 64bits canary 0x5429851ebaf95800 can't be predicted, but in specific situations is not re-generated and can be bruteforced or in other situations can be leaked from memory for example using a format string vulnerability or an arbitrary read wihout overflowing the stack.
If the canary doesn't match, the libc function __stack_chck_fail is called and terminates the prorgam with a SIGABORT which generates a coredump, in the case of archlinux managed by systemd and are stored on "/var/lib/systemd/coredump/"
❯❯❯ ./test *** stack smashing detected ***: terminated fish: './test' terminated by signal SIGABRT (Abort)
We specify the binary and the core file as a gdb parameters. We can see only one LWP (light weight process) or linux thread, so in this case is quicker to check. First of all lets see the back trace, because in this case the execution don't terminate in the segfaulted return.
We can see on frame 5 the address were it would had returned to main if it wouldn't aborted.
Happy Idea: we can use this stack canary aborts to detect stack overflows. In Debian with prevous versions it will be exploitable depending on the compilation flags used. And note that the canary is located as the last variable in the stack so the previous variables can be overwritten without problems.
Black Stealer v2.1 is an advanced keylogger that can steal even saved passwords from the browsers and sends through Email and FTP. It's really easy to the crypt. Keylogger is a computer program that is a type of surveillance technology used to monitor and record each keystroke typed on a specific computer's keyboard by the user, especially in order to gain unauthorized access to the passwords and other confidential information. It's also called a keystroke logger or system monitor. Download black stealer v2.1 full.
Printers belong arguably to the most common devices we use. They are available in every household, office, company, governmental, medical, or education institution.
From a security point of view, these machines are quite interesting since they are located in internal networks and have direct access to sensitive information like confidential reports, contracts or patient recipes.
TL;DR: In this blog post we give an overview of attack scenarios based on network printers, and show the possibilities of an attacker who has access to a vulnerable printer. We present our evaluation of 20 different printer models and show that each of these is vulnerable to multiple attacks. We release an open-source tool that supported our analysis: PRinter Exploitation Toolkit (PRET) https://github.com/RUB-NDS/PRET
Full results are available in the master thesis of Jens Müller and our paper.
Furthermore, we have set up a wiki (http://hacking-printers.net/) to share knowledge on printer (in)security. The highlights of the entire survey will be presented by Jens Müller for the first time at RuhrSec in Bochum.
Background
There are many cool protocols and languages you can use to control your printer or your print jobs. We assume you have never heard of at least half of them. An overview is depicted in the following figure and described below.
Device control
This set of languages is used to control the printer device. With a device control language it is possible to retrieve the printer name or status. One of the most common languages is the Simple Network Management Protocol (SNMP). SNMP is a UDP based protocol designed to manage various network components beyond printers as well, e.g. routers and servers.
Printing channel
The most common network printing protocols supported by printer devices are the Internet Printing Protocol (IPP), Line Printer Daemon (LPD), Server Message Block (SMB), and raw port 9100 printing. Each protocol has specific features like print job queue management or accounting. In our work, we used these protocols to transport malicious documents to the printers.
Job control language
This is where it gets very interesting (for our attacks). A job control language manages printer settings like output trays or paper size. A de-facto standard for print job control is PJL. From a security perspective it is very useful that PJL is not limited to the current print job as some settings can be made permanent. It can further be used to change the printer's display or read/write files on the device.
Page description language
A page description language specifies the appearance of the actual document. One of the most common 'standard' page description languages is PostScript. While PostScript has lost popularity in desktop publishing and as a document exchange format (we use PDF now), it is still the preferred page description language for laser printers. PostScript is a stack-based, Turing-complete programming language consisting of about 400 instructions/operators. As a security aware researcher you probable know that some of them could be useful. Technically spoken, access to a PostScript interpreter can already be classified as code execution.
Attacks
Even though printers are an important attack target, security threats and scenarios for printers are discussed in very few research papers or technical reports. Our first step was therefore to perform a comprehensive analysis of all reported and published attacks in CVEs and security blogs. We then used this summary to systematize the known issues, to develop new attacks and to find a generic approach to apply them to different printers. We estimated that the best targets are the PostScript and PJL interpreters processing the actual print jobs since they can be exploited by a remote attacker with only the ability to 'print' documents, independent of the printing channel supported by the device.
We put the printer attacks into four categories.
Denial-of-service (DoS)
Executing a DoS attack is as simple as sending these two lines of PostScript code to the printer which lead to the execution of an infinite loop:
Other attacks include:
Offline mode. The PJL standard defines the OPMSG command which 'prompts the printer to display a specified message and go offline'.
Physical damage. By continuously setting the long-term values for PJL variables, it is possible to physically destroy the printer's NVRAM which only survives a limited number of write cycles.
Showpage redefinition. The PostScript 'showpage' operator is used in every document to print the page. An attacker can simply redefine this operator to do nothing.
Protection Bypass
Resetting a printer device to factory defaults is the best method to bypass protection mechanisms. This task is trivial for an attacker with local access to the printer, since all tested devices have documented procedures to perform a cold reset by pressing certain key combinations. However, a factory reset can be performed also by a remote attacker, for example using SNMP if the device complies with RFC1759 (Printer MIB):
Other languages like HP's PML, Kyocera's PRESCRIBE or even PostScript offer similar functionalities.
Furthermore, our work shows techniques to bypass print job accounting on popular print servers like CUPS or LPRng.
Print Job Manipulation
Some page description languages allow permanent modifications of themselves which leads to interesting attacks, like manipulating other users' print jobs. For example, it is possible to overlay arbitrary graphics on all further documents to be printed or even to replace text in them by redefining the 'showpage' and 'show' PostScript operators.
Information Disclosure
Printing over port 9100 provides a bidirectional channel, which can be used to leak sensitive information. For example, Brother based printers have a documented feature to read from or write to a certain NVRAM address using PJL:
Our prototype implementation simply increments this value to dump the whole NVRAM, which contains passwords for the printer itself but also for user-defined POP3/SMTP as well as for FTP and Active Directory profiles. This way an attacker can escalate her way into a network, using the printer device as a starting point. Other attacks include:
File system access. Both, the standards for PostScript and PJL specify functionality to access the printers file system. As it seems, some manufacturers have not limited this feature to a certain directory, which leads to the disclosure of sensitive information like passwords.
Print job capture. If PostScript is used as a printer driver, printed documents can be captured. This is made possible by two interesting features of the PostScript language: First, permanently redefining operators allows an attacker to 'hook' into other users' print jobs and secondly, PostScript's capability to read its own code as data allows to easily store documents instead of executing them.
Credential disclosure. PJL passwords, if set, can easily retrieved through brute-force attacks due to their limited key space (1..65535). PostScript passwords, on the other hand, can be cracked extremely fast (up to 100,000 password verifications per second) thanks to the performant PostScript interpreters.
PRET
To automate the introduced attacks, we wrote a prototype software entitled PRET. The main idea of PRET is to facilitate the communication between the end-user and the printer. Thus, by entering a UNIX-like command PRET translates it to PostScript or PJL, sends it to the printer, and evaluates the result. For example, PRET converts a UNIX command ls to the following PJL request:
It then collects the printer output and translates it to a user friendly output.
PRET implements the following list of commands for file system access on a printer device:
Evaluation
As a highly motivated security researcher with a deep understanding of systematic analysis, you would probably obtain a list of about 20 - 30 well-used printers from the most important manufacturers, and perform an extensive security analysis using these printers. However, this was not our case. To overcome the financial obstacles, we collected printers from various university chairs and facilities. While our actual goal was to assemble a pool of printers containing at least one model for each of the top ten manufacturers, we practically took what we could get. The result is depicted in the following figure:
The assembled devices were not brand-new anymore and some of them were not even completely functional. Three printers had physically broken printing functionality so it was not possible to evaluate all the presented attacks. Nevertheless, these devices represent a good mix of printers used in a typical university or office environment.
Before performing the attacks, we of course installed the newest firmware on each of the devices. The results of our evaluation show that we could find multiple attacks against each printer. For example, simple DoS attacks with malicious PostScript files containing infinite loops are applicable to each printer. Only the HP LaserJet M2727nf had a watchdog mechanism and restarted itself after about ten minutes. Physical damage could be caused to about half of the tested device within 24 hours of NVRAM stressing. For a majority of devices, print jobs could be manipulated or captured.
PostScript, PJL and PML based attacks can even be exploited by a web attacker using advanced cross-site printing techniques. In the scope of our research, we discovered a novel approach – 'CORS spoofing' – to leak information like captured print jobs from a printer device given only a victim's browser as carrier. A proof-of-concept implementation demonstrating that advanced cross-site printing attacks are practical and a real-world threat to companies and institutions is available at http://hacking-printers.net/xsp/.
Our next post will be on adapting PostScript based attacks to websites.
