Apache 2.0.51
Apache other than 2.0.51 (e.g. 2.0.51-dev) or other web server products
Evasion
The remote host is running an Apache web server 2.0.51. This specific version is vulnerable to a bypass attack. Under special circumstances an attacker may gain elevated access privileges if the Satisfy directive is used. No further technical details are available at the moment.
If the web server and/or the Satisfy directive is not used it should be de-installed or de-activated. Install the newest patch or bugfix to solve the problem or upgrade to the latest software version which is not vulnerable anymore. Additionally limit unwanted connections and communications with firewalling.
