Overview
A security vulnerability (CVE-2025-24915) was discovered in Nessus Agent versions prior to 10.8.3. The vulnerability exists when installing Nessus Agent to a non-default location on a Windows host, where the software failed to enforce secure permissions for sub-directories (NVD, Tenable Advisory).
Technical details
The vulnerability is classified as CWE-276 (Incorrect Default Permissions) and has received a CVSS v3.1 Base Score of 7.8 (HIGH) with the following vector: AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. The technical issue stems from improper permission enforcement in sub-directories when Nessus Agent is installed in non-default locations on Windows systems (Tenable Advisory).
