Name of the Vulnerable Software and Affected Versions CISOfy Lynis versions prior to 3.0.0

Description The issue is related to Incorrect Access Control due to a TOCTOU race condition. This condition allows an unprivileged attacker to bypass the routine that checks log and report file permissions locally. As a result, the attacker can set up a log and report file, control it until the check is performed, and then remove, recreate, and use the file for further attacks.

Recommendations For versions prior to 3.0.0, update to version 3.0.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the log and report files to minimize the risk of exploitation.
