 Advisory Content : ----------------------------------------
Synopsis
----------------------------------------
WinGate is vulnerable to denial-of-service (DoS) attacks caused
probably by a resource exhaustion vulnerability.
The IMAP server ceases to provide access to its clients after
processing a LIST command with a large parameter (see details bellow).
Product: WinGate
Version: 6.2.2 and probably the older versions
Vendor: Qbik (www.wingate.com)
Type: Denial-of-service
Risk: service disruption
Remote: Yes
Discovered by: João Antunes (AJECT -- Attack Injection Tool) on
14/May/
2008
Exploit: Not Available
Solution: Not Available
Status: Developers were contacted several times since the
vulnerability was discovered.
----------------------------------------
Vulnerability Description
----------------------------------------
The vulnerability can be triggered by sending the following messages
to the imap server:
A01 LOGIN <user> <password>
A02 LIST Ax1000 *
Depending on the server's resources, it may be required to repeat the
above exploit to deplete its resources. (in a 512MB RAM configuration,
the exploit was executed twice)
The above exploit caused the server to reject all subsequent
connections with a "NO access denied" reply thus resulting in a remote
denial of service.
