The problem is that no redirection occurs when accessing the "mail" script with the "A" parameter referencing a valid local file via directory traversal attacks. Example: http://[host]/mail?A=/../../../../../../../[file] This can further be exploited to cause a vulnerable server to create a large amount of processes consuming memory by sending multiple requests (several thousand). The vulnerability has been confirmed in version 2004.0.05.0413. Other versions may also be affected. SOLUTION: Filter malicious characters and character sequences in a proxy or firewall with URL filtering capabilities.
