This Metasploit module exploits CVE-2019-1458, an arbitrary pointer dereference vulnerability within win32k which occurs due to an uninitialized variable, which allows user mode attackers to write a limited amount of controlled data to an attacker controlled address in kernel memory. 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 Windows 7 x64 SP1. Offsets within the exploit code may need to be adjusted to work with other versions of Windows. The exploit can only be triggered once against the target and can cause the target machine to reboot when the session is terminated.
965825e462e62b73a8b4edd4aeb9b9d17c52ab810644e44a21ae2613d7a92025This Metasploit module exploits an elevation of privilege vulnerability that exists in Windows 7 and 2008 R2 when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploits this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. This Metasploit module is tested against windows 7 x86, windows 7 x64 and windows server 2008 R2 standard x64.
