|5||(AV:N/AC:L/Au:N/C:P/I:N/A:N)||July 06, 2011||October 30, 2017||October 30, 2017|
The default configuration of the SIP channel driver in Asterisk Open Source 1.4.x through 184.108.40.206 and 1.6.2.x through 220.127.116.11.2 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.
