CVE-2023-37250

Name of the Vulnerable Software and Affected Versions Unity Parsec versions prior to 9 Parsec Loader versions prior to 9

Description The issue is a Time-of-check-to-time-of-use (TOCTOU) race condition that allows local attackers to escalate privileges to SYSTEM if Parsec was installed in "Per User" mode. The application intentionally launches DLLs from a user-owned directory but intended to always perform integrity verification of those DLLs.

Recommendations For Unity Parsec versions prior to 9, update to version 9 to resolve the issue. For Parsec Loader versions prior to 9, update to version 9 to resolve the issue. As a temporary workaround, consider restricting access to the user-owned directory where the DLLs are launched to minimize the risk of exploitation.
