Sase Client
Monthly
Local privilege escalation in Versa SASE Client for Windows (versions 7.8.7 through 7.9.4) allows authenticated local users to achieve NT AUTHORITY\SYSTEM execution by abusing the audit log export feature. The client passes user-controlled file paths to a privileged background service that performs file system operations without impersonating the caller, and a TOCTOU race window combined with symbolic link and mount point manipulation coerces the service into deleting arbitrary directories as SYSTEM. Deletion of protected Windows Installer directories such as C:\Config.msi, followed by MSI rollback techniques, yields full SYSTEM code execution. No public exploit code or CISA KEV listing has been identified at time of analysis.
