https://notcve.org/view.php?id=CVE-2011-4597
The SIP over UDP implementation in Asterisk Open Source 1.4.x before 1.4.43, 1.6.x before 1.6.2.21, and 1.8.x before 1.8.7.2 uses different port numbers for responses to invalid requests depending on whether a SIP username exists, which allows remote attackers to enumerate usernames via a series of requests. La implementación de SIP sobre UDP de Asterisk Open Source 1.4.x anteriores a 1.4.43, 1.6.x anteriores a 1.6.2.21, y 1.8.x anteriores a 1.8.7.2 utiliza diferentes números de puertos para respuestas a peticiones inválidas dependiendo de si el nombre de usuario SIP existe, lo que permite a atacantes remotos enumerar nombres de usuario a través de series de peticiones. • http://archives.neohapsis.com/archives/bugtraq/2011-12/0151.html http://downloads.asterisk.org/pub/security/AST-2011-013.html http://lists.digium.com/pipermail/asterisk-dev/2011-November/052191.html http://openwall.com/lists/oss-security/2011/12/09/3 http://openwall.com/lists/oss-security/2011/12/09/4 http://osvdb.org/77597 http://secunia.com/advisories/47273 http://www.debian.org/security/2011/dsa-2367 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
