CVE-2025-34290 | BDVDB-2026-307167 Detail

Description#

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.
