Overview
CVE-2024-3291 affects Nessus Agent versions prior to 10.6.4. The vulnerability was discovered when installing Nessus Agent to a directory outside of the default location on a Windows host, where the application failed to enforce secure permissions for sub-directories. The vulnerability was reported on February 26, 2024, confirmed as valid on March 5, 2024, and was patched with the release of Nessus Agent 10.6.4 on May 16, 2024 (Tenable Advisory).
Technical details
