What to do
AI-suggested
1. Immediately audit and restrict file and folder permissions related to prunsrv.exe and associated directories to ensure only trusted administrative accounts have write access. 2. Implement strict local user account controls and limit the number of users with local access to affected systems. 3. Monitor system logs and file integrity for unauthorized changes to prunsrv.exe or related files. 4. Deploy endpoint detection and response (EDR) tools capable of detecting privilege escalation attempts and anomalous process executions. 5. Apply vendor patches or updates as soon as they become available; maintain close communication with Vivavis for patch release notifications. 6. Use application whitelisting to prevent unauthorized executables from running. 7. Segment networks to limit local access to critical systems running HIGH-LEIT software. 8. Conduct regular security awareness training for personnel with local system access to reduce insider threat risks. 9. Consider implementing least privilege principles and multi-factor authentication for administrative access to reduce the risk of credential compromise.
Description
HIGH-LEIT V05.08.01.03 and HIGH-LEIT V04.25.00.00 to 4.25.01.01 for Windows from Vivavis contain an insecure file and folder permissions vulnerability in prunsrv.exe. A regular user (non-admin) can exploit the weak folder and file permissions to escalate privileges and execute arbitrary code in the context of NT AUTHORITY\SYSTEM.
