Ipswitch IMail Server IMAP LIST Command Remote Overflow DoS
High Nessus Plugin ID 20320
The remote IMAP server is affected by a denial of service vulnerability.
The remote host is running Ipswitch Collaboration Suite or IMail Server, commercial messaging and collaboration suites for Windows. The version of Ipswitch Collaboration Suite / IMail server installed on the remote host contains an IMAP server that suffers from a denial of service flaw. Using a specially crafted LIST command of around 8000 bytes, an authenticated attacker can crash the IMAP server on the affected host, thereby denying service to legitimate users.
Upgrade to Ipswitch Collaboration Suite 2.02 / IMail 8.22 or later.
