CVE-2024-3291: Tenable Nessus Agent

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

When installing Nessus Agent to a directory outside of the default location on a Windows host, Nessus Agent versions prior to 10.6.4 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location.

Affected products

• Tenable Nessus Agent: before 10.6.4 (fixed in 10.6.4)
