Buffer Overflow
The remote host is running an Apache web server. It has been reported that in Apache web server prior 2.0.49 has an information disclosure in the module mod_userdir. An attacker may gain sensitive data about the target after exploitation.
If 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.
