Descriptions

Cyrus IMAP 2.5.x before 2.5.14 and 3.x before 3.0.12 allows privilege escalation because an HTTP request may be interpreted in the authentication context of an unrelated previous request that arrived over the same connection.

Cyrus IMAP versiones 2.5.x anteriores a la versión 2.5.14 y versiones 3.x anteriores a la versión 3.0.12, permite una escalada de privilegios porque una petición HTTP puede ser interpretada en el contexto de autenticación de una petición anterior no relacionada que llegó por medio de la misma conexión.
