Chrome 72.0.3626.119 FileReader Use-After-Free
Posted May 8, 2019
Authored by Clement LECIGNE, timwr, Istvan Kurucsai | Site metasploit.com

This exploit takes advantage of a use after free vulnerability in Google Chrome 72.0.3626.119 running on Windows 7 x86. The FileReader.readAsArrayBuffer function can return multiple references to the same ArrayBuffer object, which can be freed and overwritten with sprayed objects. The dangling ArrayBuffer reference can be used to access the sprayed objects, allowing arbitrary memory access from Javascript. This is used to write and execute shellcode in a WebAssembly object. The shellcode is executed within the Chrome sandbox, so you must explicitly disable the sandbox for the payload to be successful.
