GHSA-X6V7-6Q76-P2CX

Vulnerability from github – Published: 2025-12-20 21:30 – Updated: 2025-12-20 21:30

Details

Versa SASE Client for Windows versions released between 7.8.7 and 7.9.4 contain a local privilege escalation vulnerability in the audit log export functionality. The client communicates user-controlled file paths to a privileged service, which performs file system operations without impersonating the requesting user. Due to improper privilege handling and a time-of-check time-of-use race condition combined with symbolic link and mount point manipulation, a local authenticated attacker can coerce the service into deleting arbitrary directories with SYSTEM privileges. This can be exploited to delete protected system folders such as C:\Config.msi and subsequently achieve execution as NT AUTHORITY\SYSTEM via MSI rollback techniques.

Severity ?

8.5 (High)

Title

Versa SASE Client for Windows < 7.9.5 Arbitrary Folder Deletion Leading to Local Privilege Escalation

Summary
