CVE-2013-2264

https://notcve.org/view.php?id=CVE-2013-2264

The SIP channel driver in Asterisk Open Source 1.8.x before 1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15 before 1.8.15-cert2; Asterisk Business Edition (BE) C.3.x before C.3.8.1; and Asterisk Digiumphones 10.x-digiumphones before 10.12.2-digiumphones exhibits different behavior for invalid INVITE, SUBSCRIBE, and REGISTER transactions depending on whether the user account exists, which allows remote attackers to enumerate account names by (1) reading HTTP status codes, (2) reading additional text in a 403 (aka Forbidden) response, or (3) observing whether certain retransmissions occur. El controlador del canal SIP en Asterisk Open Source v1.8.x antes de v1.8.20.2, v10.x antes v10.12.2 y v11.2.2 anterior a v11.x; Certified Asterisk v1.8.15 antes v1.8.15-cert2, Asterisk Business Edition (BE) vC.3.x antes vC.3.8.1 y Digiumphones Asterisk 10.x-digiumphones antes v10.12.2-digiumphones muestra un comportamiento diferente para transacciones INVITE, SUBSCRIBE y REGISTER inválidas en función de si la cuenta de usuario existe, lo que permite a atacantes remotos para enumerar los nombres de cuenta de (1) los códigos de estado HTTP de lectura, (2) la lectura de un texto adicional en un 403 (también conocido como Forbidden) respuesta, o (3) observando si se producen ciertas retransmisiones. • http://downloads.asterisk.org/pub/security/AST-2013-003.html https://issues.asterisk.org/jira/browse/ASTERISK-21013 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVE-2013-2686

https://notcve.org/view.php?id=CVE-2013-2686

main/http.c in the HTTP server in Asterisk Open Source 1.8.x before 1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15 before 1.8.15-cert2; and Asterisk Digiumphones 10.x-digiumphones before 10.12.2-digiumphones does not properly restrict Content-Length values, which allows remote attackers to conduct stack-consumption attacks and cause a denial of service (daemon crash) via a crafted HTTP POST request. NOTE: this vulnerability exists because of an incorrect fix for CVE-2012-5976. main/http.c en el servidor HTTP Asterisk Open Source v1.8.x antes de v1.8.20.2, v10.x antes v10.12.2 y v11.2.2 v11.x antes; Certified Asterisk v1.8.15 antes de v8.1.15-cert2; y Digiumphones Asterisk v10.x-digiumphones antes de v10.12.2-digiumphones no restringe correctamente valores Content-Length, que permite a atacantes remotos realizar ataques de consumo de la pila y provocar una denegación de servicio (caída del demonio) a través de una petición POST HTTP manipulada. NOTA: esta vulnerabilidad se debe a una solución incorrecta para CVE-2012-5976. • http://downloads.asterisk.org/pub/security/AST-2013-002.html http://telussecuritylabs.com/threats/show/TSL20130327-01 https://issues.asterisk.org/jira/browse/ASTERISK-20967 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
