Detailsinfo

A vulnerability classified as critical was found in Frederik Vermeulen netqmail 1.06 (Mail Server Software). This vulnerability affects an unknown function of the file qmail-smtpd.c. The manipulation with an unknown input leads to a command injection vulnerability. The CWE definition for the vulnerability is CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The STARTTLS implementation in qmail-smtpd.c in qmail-smtpd in the netqmail-1.06-tls patch for netqmail 1.06 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 shared 03/16/2011 by Wietse Venema as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability was named CVE-2011-1431 since 03/16/2011. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

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.
