AI-suggested
1. Immediate upgrade: Organizations should prioritize upgrading Tenable Agent to version 10.8.5 or later where this vulnerability is addressed. 2. Privilege restriction: Limit local user privileges strictly to reduce the number of users with local access to endpoints running the vulnerable agent. 3. File integrity monitoring: Implement monitoring solutions to detect unauthorized modifications to critical system files, especially those potentially targeted by log overwrites. 4. Application whitelisting: Employ application control policies to prevent unauthorized execution or modification of system files by non-administrative users. 5. Endpoint detection and response (EDR): Enhance endpoint monitoring to detect suspicious activities indicative of privilege escalation attempts. 6. Network segmentation: Restrict lateral movement by segmenting networks so that compromised endpoints have limited access to critical systems. 7. Incident response readiness: Prepare playbooks for rapid containment and remediation if exploitation is detected. 8. Audit and review: Regularly audit local user accounts and permissions to ensure minimal privilege principles are enforced. 9. Vendor communication: Monitor Tenable’s advisories for official patches or workarounds and apply them promptly once available.
Description
In Tenable Agent versions prior to 10.8.5 on a Windows host, it was found that a non-administrative user could overwrite arbitrary local system files with log content at SYSTEM privilege.
