Bug vulnerability class | Evasion |
Bug description | The remote host is running an Apache web server. A vulnerability has been discovered in the Apache web server prior 2.0.49 that if the requested resource is served by an Apache module and not by Apache Server itself, LIMIT restrictions may not apply. Additionally, CGI/Script resources that do not sufficiently check the calling method may potentially be invoked with methods not listed in the LIMIT clause to evade LIMIT restrictions. |
Bug solution | 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. |
