Name of the Vulnerable Software and Affected Versions lighttpd versions prior to 1.4.33

Description The issue is related to the failure of lighttpd to check the return value of certain functions, specifically setuid, setgid, and setgroups. This oversight might cause lighttpd to run as root if it is restarted, potentially allowing remote attackers to gain privileges. This can be demonstrated through multiple calls to the clone function, which can cause setuid to fail when the user process limit is reached.

Recommendations For versions prior to 1.4.33, update to version 1.4.33 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive resources and monitoring system logs for potential exploitation attempts.
