FKIE_CVE-2011-1506
Vulnerability from fkie_nvd - Published: 2011-03-22 17:55 - Updated: 2026-06-16 23:29
Severity
Summary
The STARTTLS implementation in Kerio Connect 7.1.4 build 2985 and MailServer 6.x 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. NOTE: some of these details are obtained from third party information.
