Description

This module exploits CVE-2020-1054, an out of bounds write reachable from DrawIconEx within win32k. The out of bounds write can be used to overwrite the pvbits of a SURFOBJ. By utilizing this vulnerability to execute controlled writes to kernel memory, an attacker can gain arbitrary code execution as the SYSTEM user. This module has been tested against a fully updated Windows 7 x64 SP1. Offsets within the exploit code may need to be adjusted to work with other versions of Windows.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
