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.
