3eb904edf84797c8c3688bec6a97022eThis 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.

b50ae92a79eb994d20eae879ab538a64This 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.

736ab2fee6b1fc77956e403631161630This Metasploit module exploits a buffer overflow in Free MP3 CD Ripper versions 2.6 and 2.8. By constructing a specially crafted WMA WAV M3U ACC FLAC file and attempting to convert it to an MP3 file in the application, a buffer is overwritten, which allows for running shellcode.
93482b8f1d9c8f6f9b71706c24ed882aA trivial to reach stack-based buffer overflow is present in libpam on Solaris. The vulnerable code exists in pam_framework.c parse_user_name() which allocates a fixed size buffer of 512 bytes on the stack and parses a username supplied to PAM modules (such as authtok_get used by SunSSH). This issue can be reached remotely pre-authentication via SunSSH when "keyboard-interactive" is enabled to use PAM based authentication. The vulnerability was discovered being actively exploited by FireEye in the wild and is part of an APT toolkit called "EVILSUN". The vulnerability is present in both SPARC/x86 versions of Solaris and others (eg. illumos). This exploit uses ROP gadgets to disable nxstack through mprotect on x86 and a helper shellcode stub. Tested against latest Solaris 10 without patch applied and the configuration is vulnerable in a default vanilla install. This exploit requires libssh2, the vulnerability has been identified and confirmed reachable on Solaris 10 through 11.0.
3fbcd0fdda16b92f50dc244f60276db1This Metasploit module exploits an incorrect side-effect modeling of the 'in' operator. The DFG compiler assumes that the 'in' operator is side-effect free, however the embed element with the PDF plugin provides a callback that can trigger side-effects leading to type confusion (CVE-2020-9850). The type confusion can be used as addrof and fakeobj primitives that then lead to arbitrary read/write of memory. These primitives allow us to write shellcode into a JIT region (RWX memory) containing the next stage of the exploit. The next stage uses CVE-2020-9856 to exploit a heap overflow in CVM Server, and extracts a macOS application containing our payload into /var/db/CVMS. The payload can then be opened with CVE-2020-9801, executing the payload as a user but without sandbox restrictions.

19e25cdfd1453bac178a73395ba04bfaThis Metasploit module exploits a JIT optimization bug in Safari Webkit. This allows us to write shellcode to an RWX memory section in JavaScriptCore and execute it. The shellcode contains a kernel exploit (CVE-2016-4669) that obtains kernel rw, obtains root and disables code signing. Finally we download and execute the meterpreter payload. This module has been tested against iOS 7.1.2 on an iPhone 4.
