https://notcve.org/view.php?id=CVE-2011-2666
The default configuration of the SIP channel driver in Asterisk Open Source 1.4.x through 1.4.41.2 and 1.6.2.x through 1.6.2.18.2 does not enable the alwaysauthreject option, which allows remote attackers to enumerate account names by making a series of invalid SIP requests and observing the differences in the responses for different usernames, a different vulnerability than CVE-2011-2536. La configuración por defecto del controlador del canal SIP en Asterisk Open Source 1.4.x hasta 1.1.41.2 y 1.6.2.x hasta 1.6.2.18.2 no activa la opción alwaysauthreject, lo que permite a atacantes remotos enumerar los nombres de las cuentas al hacer una serie de peticiones SIP inválidas y observando las diferencias en las respuestas para distintos nombres de usuario, es una vulnerabilidad distinta a CVE-2011-2536. • http://downloads.asterisk.org/pub/security/AST-2011-011.html https://exchange.xforce.ibmcloud.com/vulnerabilities/68472 • CWE-16: Configuration •
