which can be exploited by malicious people to bypass certain security
restrictions.

to properly validate credentials that are submitted via cookies before
allowing access. This can be exploited to gain access to the "File
Scan" functionality without requiring knowledge of the username and
password.

The vulnerability has been confirmed in version 2.0 (20050817). Other
