CVE-2014-3556 (GCVE-0-2014-3556)

Vulnerability from cvelistv5 – Published: 2014-12-29 20:00 – Updated: 2024-08-06 10:50
VLAI
Summary
The STARTTLS implementation in mail/ngx_mail_smtp_handler.c in the SMTP proxy in nginx 1.5.x and 1.6.x before 1.6.1 and 1.7.x before 1.7.4 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.
