Detail
| The STARTTLS implementation in Cyrus IMAP Server before 2.4.7 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted 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. |

| Id | Description |
|---|---|
| 72186 | Cyrus IMAP Server STARTTLS Arbitrary Plaintext Command Injection Cyrus IMAP Server contains a flaw related to the TLS implementation failing to properly clear transport layer buffers when changing from plaintext to ciphertext upon receipt of the 'STARTTLS' command. This may allow a remote attacker to inject arbitrary plaintext data which will be executed upon transition to ciphertext. |
