CVE-2011-4318 describes a vulnerability in Dovecot 2.0.x before 2.0.16 where, when SSL/STARTTLS is enabled and hostname is used for proxy destination, the server fails to verify the hostname against the X.509 certificate's Common Name. This allows man-in-the-middle attackers to spoof SSL servers using a valid certificate for a different hostname, leading to potential information disclosure and integrity compromise. With a CVSS score of 5.8, this vulnerability is of medium severity, requiring medium attack complexity and no authentication, but there is no evidence of active exploitation, public exploit code, or significant community discussion.
