CVE-2011-2165 – Watchguard XCS 10.0 - Multiple Vulnerabilities

https://notcve.org/view.php?id=CVE-2011-2165

The STARTTLS implementation in WatchGuard XCS 9.0 and 9.1 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP 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 de STARTTLS en WatchGuard XCS v9.0 y v9.1 no restringe de forma correcta el búfer de I/O, lo que permite que mediante ataques de "hombre en medio", se inserten comandos el las sesiones SMTP cifradas, enviando un comando en texto plano, que es procesado después de TLS en su lugar, en relación a una " inyección de comandos de texto claro " ataque, un problema similar a CVE-2011-0411. • https://www.exploit-db.com/exploits/37440 http://secunia.com/advisories/44753 http://www.kb.cert.org/vuls/id/555316 http://www.kb.cert.org/vuls/id/MAPG-8D9M75 http://www.watchguard.com/support/release-notes/xcs/9/en-US/EN_ReleaseNotes_XCS_9_1_1/EN_ReleaseNotes_WG_XCS_9_1_TLS_Hotfix.pdf https://exchange.xforce.ibmcloud.com/vulnerabilities/67729 • CWE-264: Permissions, Privileges, and Access Controls •
