CVE-2025-34290 is a local privilege escalation vulnerability in Versa SASE Client for Windows versions 7.8.7 through 7.9.4. The vulnerability resides in the audit log export functionality, where user-controlled file paths are sent to a privileged service that performs file system operations without impersonating the requesting user. This, combined with a time-of-check time-of-use (TOCTOU) race condition and symbolic link or mount point manipulation, allows a local authenticated attacker to coerce the service into deleting arbitrary directories with SYSTEM privileges. Exploitation can result in deletion of protected system folders such as C:\Config.msi, enabling attackers to achieve NT AUTHORITY\SYSTEM execution via MSI rollback techniques.
