<bug_vulnerability_class>Directory Traversal</bug_vulnerability_class>
<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 if it is used within a cygwin environment. An attacker may be able to reach files outside the web server directory by using a directory traversal attack with encoded special characters.</bug_description>
<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.</bug_solution>
