Discussion

IPSwitch IMail Web Messaging HTTP Get Buffer Overflow Vulnerability

IMail is a commercial email server software package distributed and maintained by Ipswitch, Incorporated. IMail is available for Microsoft Operating Systems.

The web messaging server is vulnerable to a buffer overflow. When the server receives a request for HTTP version 1.0, and the total request is 96 bytes or greater, a buffer overflow occurs. This could result in the execution of attacker-supplied instructions, and potentially allow an attacker to gain local access.

** Ipswitch has reported they are unable to reproduce this issue. In addition, Ipswitch has stated that the supplied, third party patch may in fact open additional vulnerabilities in the product. Ipswitch suggests that users do not apply the supplied patch.
