GHSA-4J5R-P7P6-V9J4

Vulnerability from github – Published: 2024-09-04 15:30 – Updated: 2024-09-04 15:30

Details

A local privilege escalation is caused by Overwolf loading and executing certain dynamic link library files from a user-writeable folder in SYSTEM context on launch. This allows an attacker with unprivileged access to the system to run arbitrary code with SYSTEM privileges by placing a malicious .dll file in the respective location.

Severity ?

7.8 (High)
