Description

Dr_insane has discovered a vulnerability in 602LAN SUITE, which can be exploited by malicious people to detect the presence of local files and cause a DoS (Denial of Service).

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
Update to build 2004.0.05.0509.
