Until a fix is available, restrict access to the munin-httpd service and monitor for suspicious requests targeting the static file handler.
Description
Munin munin-httpd versions 2.99.1 through 2.999.18 contain a path traversal vulnerability in the static file handler. This flaw allows unauthenticated attackers to bypass directory restrictions and read sensitive configuration files such as munin.conf and plugin-conf.d, which may contain monitored service credentials. The vulnerability arises from improper handling of '/../' sequences in file path requests.
