The output file will always have the same MD5 hash: 3cebbe60d91ce760409bbe513593e401. Currently, only Linux x86-64 is supported. It would be trivial to port this technique to other platforms, although each version would end up with a different MD5.

9e6475d7e02bb5bcc0b7670b1ca005b4e4ecb987abc3fd2dcd7a5d44af829d04This Metasploit module exploits a stack buffer overflow in the Cisco RV series router's SSL VPN functionality. The default SSL VPN configuration is exploitable, with no authentication required and works over the Internet! The stack is executable and no ASLR is in place, which makes exploitation easier. Successful execution of this module results in a reverse root shell. A custom payload is used as Metasploit does not have ARMLE null free shellcode. This vulnerability was presented by the Flashback Team in Pwn2Own Austin 2021 and OffensiveCon 2022. For more information check the referenced advisory. This module has been tested in firmware versions 1.0.03.15 and above and works with around 65% reliability. The service restarts automatically so you can keep trying until you pwn it. Only the RV340 router was tested, but other RV series routers should work out of the box.

79b9b9a6dd757b66b2e94d3630b76899ed2e53218846c0933182d8877820babbThis Metasploit modules exploits CVE-2020-26950, a use-after-free exploit in Firefox. The MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition. This exploit uses a somewhat novel technique of spraying ArgumentsData structures in order to construct primitives. The shellcode is forced into executable memory via the JIT compiler, and executed by writing to the JIT region pointer. This exploit does not contain a sandbox escape, so firefox must be run with the MOZ_DISABLE_CONTENT_SANDBOX environment variable set, in order for the shellcode to run successfully. This vulnerability affects Firefox versions prior to 82.0.3, Firefox ESR versions prior to 78.4.1, and Thunderbird versions prior to 78.4.2, however only Firefox versions up to 79 are supported as a target. Additional work may be needed to support other versions such as Firefox 82.0.1.

This a bind tcp shellcode that open a listen socket on 0.0.0.0 and port 1337. In order to accomplish this task the shellcode uses the PEB method to locate the baseAddress of the required module and the Export Directory Table to locate symbols. Also the shellcode uses a hash function to gather dynamically the required symbols without worry about the length.
