IMPACT:
Exposure of system information, DoS
WHERE:
>From remote
SOFTWARE:
602LAN SUITE 2004
http://secunia.com/product/4219/
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:
Filter malicious characters and character sequences in a proxy or
firewall with URL filtering capabilities.
