What to do
AI-suggested
- Immediately audit and restrict file and folder permissions related to prunsrv.exe and associated directories to ensure only trusted administrative accounts have write access.
- Implement strict local user account controls and limit the number of users with local access to affected systems.
- Monitor system logs and file integrity for unauthorized changes to prunsrv.exe or related files.
- Deploy endpoint detection and response (EDR) tools capable of detecting privilege escalation attempts and anomalous process executions.
- Apply vendor patches or updates as soon as they become available; maintain close communication with Vivavis for patch release notifications.
- Use application whitelisting to prevent unauthorized executables from running.
- Segment networks to limit local access to critical systems running HIGH-LEIT software.
- Conduct regular security awareness training for personnel with local system access to reduce insider threat risks.
- 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.
