Bug vulnerability classConfiguration
Bug descriptionThe remote host is running an Apache web server. It has been reported that in Apache web server prior 2.0.49 has a file descriptor leakage in the module mod_perl. This issue could be exploited by an attacker to hijack a vulnerable server daemon. Other attacks are also possible.
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.
