DESCRIPTION:
A security issue has been reported in Asterisk, which can be
exploited by malicious people to bypass certain security
restrictions.
The security issue is caused due to missing checks of IP addresses
when processing database-based registrations ("realtime"). This can
be exploited to authenticate as a legitimate user without a
password.
Successful exploitation requires that host-based authentication is
used and that the attacker has knowledge of a valid username.
The security issue affects the following products and versions:
* Asterisk Open Source 1.2.x prior to 1.2.26
* Asterisk Open Source 1.4.x prior to 1.4.16
* Asterisk Business Edition B.x.x prior to B.2.3.6
* Asterisk Business Edition C.x.x prior to C.1.0-beta8
SOLUTION:
Update to a fixed version.
Asterisk Open Source 1.2.x:
Update to version 1.2.26.
Asterisk Open Source 1.4.x:
Update to version 1.4.16.
Asterisk Business Edition B.x.x:
Update to version B.2.3.6.
Asterisk Business Edition C.x.x:
Fixed in version C.1.0-beta8.
