Ipswitch IMail Server 2006 Multiple IMAP Buffer Overflow Vulnerabilities
------------------------------------------------------------------------
SUMMARY
<http://ipswitch.com/products/imail/index.asp > Ipswitch Inc.'s IMail
Server is "an e-mail server aimed at providing easily configured and
maintained e-mail services for small organizations". Remote exploitation
of multiple buffer overflow vulnerabilities in Ipswitch Inc.'s IMail
Server 2006 could allow attackers to execute arbitrary code.
DETAILS
Vulnerable Systems:
* IMail Server 2006. The vulnerable executable used was version 6.8.8.1
of imapd32.exe.
IMail includes an IMAP daemon that users can use to access their email.
The "Search" IMAP command contains an exploitable stack-based buffer
overflow vulnerability. Additionally, the "Search charset" contains an
exploitable heap-based buffer overflow vulnerability.
Exploitation allows an attacker to execute arbitrary code with SYSTEM
privileges.
In order to exploit these issues, an attacker would need to login to a
vulnerable IMail IMAP Server using valid credentials.
The vulnerable component is installed with any IPSwitch product that
includes the IMail Server. This includes products such as its
Collaboration Suite packages.
Disabling the IMAP service prevents exploitation of these vulnerabilities.
Consider enabling POP3 or webmail as an alternative to IMAP.
Vendor Status:
Ipswitch Inc. has released version 2006.21 of its IMail product to address
these vulnerabilities. More information can be found at the following URL.
