<plugin_comment>This is not exactly the same test as like Nessus 10039 is. We don't check for browsability - We check for existence/forbidden.</plugin_comment>

<bug_description>An attacker can try to reach /cgi-bin as a possible directory for CGI scripts. If he gets an Forbidden error he could determine that this directory exists and is used. This information can be used for further attempts.</bug_description>
<bug_solution>Do not allow users to get the directory listing of the cgi directory.</bug_solution>
