Technical details
A malicious Unix compliance audit created by an authenticated, low-privileged Nessus user can be leveraged to read arbitrary text files on the scanner host with the privileges of the nessusd process. This is an authorization bypass (CWE-863) affecting the compliance audit feature on Linux systems. The attack requires scan-creation privileges but no elevated user role, and exploitation leaves no indication of being exploited in the wild at the time of disclosure.
