CVE-2011-1926
Estado: ModificadaMedia (5.1)—
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.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:H/Au:N/C:P/I:P/A:P
- Puntuación base: 5.1
