Severity CVSS Published Added Modified
5 (AV:N/AC:L/Au:N/C:P/I:N/A:N) July 06, 2011 October 30, 2017 October 30, 2017

Description

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.
