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.

The shellcode uses the PEB method to locate the baseAddress of the required module and the Export Directory Table to locate symbols. It also uses a hash function to dynamically gather the required symbols without worry about the length. Finally, the shellcode pops the calc.exe using WinExec and exits gracefully using TerminateProcess.

7640bb0b2bdd99b08b0876002140a299d855d4c3abe7f76eb8c7c4c0c63ed8bdThis Metasploit module exploits an issue in Google Chrome versions before 87.0.4280.88 (64 bit). The exploit makes use of an integer overflow in the SimplifiedLowering phase in turbofan. It is used along with a typer hardening bypass using ArrayPrototypeShift to create a JSArray with a length of -1. This is abused to gain arbitrary read/write into the isolate region. Then an ArrayBuffer can be used to achieve absolute arbitrary read/write. The exploit then uses WebAssembly in order to allocate a region of RWX memory, which is then replaced with the payload shellcode. The payload is executed within the sandboxed renderer process, the browser must be run with the --no-sandbox option for the payload to work correctly.

0b6f0d113dff3fe9e7fd8830f15d89012a24c53b6fd740940fa27df4be7c06feThis Metasploit module exploit BITS behavior which tries to connect to the local Windows Remote Management server (WinRM) every times it starts. The module launches a fake WinRM server which listen on port 5985 and triggers BITS. When BITS starts, it tries to authenticate to the Rogue WinRM server, which allows to steal a SYSTEM token. This token is then used to launch a new process as SYSTEM user. In the case of this exploit, notepad.exe is launched as SYSTEM. Then, it writes shellcode in its previous memory space and trigger its execution. As this exploit uses reflective dll injection, it does not write any file on the disk. Vulnerable operating systems are Windows 10 and Windows servers where WinRM is not running. Lab experiments has shown that Windows 7 does not exhibit the vulnerable behavior.
