Details

Munin munin-httpd 2.99.1 through 2.999.18 contains a path traversal vulnerability in the static file handler of Munin::Master::HTML::handle_request that allows unauthenticated attackers to read files outside the static directory. Attackers can request /static/../ to bypass the '/../' substring check and read munin.conf and plugin-conf.d files containing monitored service credentials.
