This Metasploit module exploits an issue in the V8 engine on x86_x64 builds of Google Chrome versions prior to 89.0.4389.128/90.0.4430.72 when handling XOR operations in JIT'd JavaScript code. Successful exploitation allows an attacker to execute arbitrary code within the context of the V8 process. As the V8 process is normally sandboxed in the default configuration of Google Chrome, the browser must be run with the --no-sandbox option for the payload to work correctly.

1cace43b452705e7d3b72d7ffc4cfa52f96f982d0385e1b41735a6a9d29c96ceThis 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.
