Detailsinfo

A vulnerability was found in Digium Asterisk (Communications System). It has been classified as critical. This affects an unknown functionality of the file manager.conf of the component Manager Interface. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

The Manager Interface in Asterisk before 1.2.18 and 1.4.x before 1.4.3 allows remote attackers to cause a denial of service (crash) by using MD5 authentication to authenticate a user that does not have a password defined in manager.conf, resulting in a NULL pointer dereference.

The weakness was shared 04/25/2007 by Michael Spruel, Jeremy Lee and Peter Nguyen (Website). The advisory is shared at secunia.com. This vulnerability is uniquely identified as CVE-2007-2294 since 04/26/2007. The exploitability is told to be easy. It is possible to initiate the attack remotely.
