Bug vulnerability classUnknown
Bug descriptionThe remote host is running an Apache web server. It has been reported that in Apache web server prior 2.0.47 a memory corruption weakness in mod_auth is given. An attacker can use a malformed password to start the attack on 16 and 64 bit systems. Exploitation of these conditions may result in the execution of arbitrary code.
Bug solutionIf the web server 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. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8081). Alternation of the application banner can confuse an attacker and let him determine the wrong software. Additionally limit unwanted connections and communications with firewalling.
