Multiple Vendors STARTTLS Implementation Plaintext Arbitrary Command Injection Vulnerability
Publish date: May 31, 2016
Severity: MEDIUM
CVE Identifier: CVE-2011-0411
Advisory Date: MAY 31, 2016
DESCRIPTION
The STARTTLS implementation in Postfix 2.4.x before 2.4.16, 2.5.x before 2.5.12, 2.6.x before 2.6.9, and 2.7.x before 2.7.3 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.
