Descriptions

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.

La implementación STARTTLS en Cyrus IMAP Server anterior a v2.4.7 no restringe adecuadamente el búfer de Entrada/Salida, lo que permite ataques "man-in-the-middle" para insertar comandos en sesiones cifradas enviando un comando en texto claro que se procesa después de TLS en su lugar, relacionado con un ataque "inyección de comandos de texto claro", una tarea similar a CVE-2011-0411.
