A vulnerability classified as critical has been found in Ipswitch IMail (Mail Server Software). This affects some unknown processing. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The STARTTLS implementation in the server in Ipswitch IMail 11.03 and earlier does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.

The weakness was presented 03/07/2011 by Wietse Venema as confirmed advisory (CERT.org). The advisory is shared at kb.cert.org. This vulnerability is uniquely identified as CVE-2011-1430 since 03/16/2011. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 52611 (SMTP Service STARTTLS Plaintext Command Injection), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SMTP problems.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 11309.

The vulnerability is also documented in the databases at X-Force (65932) and Tenable (52611). See 56911, 56855, 56854 and 56843 for similar entries.
