Detailsinfo

A vulnerability, which was classified as problematic, was found in znc. This affects an unknown code block of the file znc.cpp of the component Administration Page. 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:

znc.cpp in ZNC before 0.092 allows remote authenticated users to cause a denial of service (crash) by requesting traffic statistics when there is an active unauthenticated connection, which triggers a NULL pointer dereference, as demonstrated using (1) a traffic link in the web administration pages or (2) the traffic command in the /znc shell.

The weakness was presented 07/12/2010 (Website). It is possible to read the advisory at znc.svn.sourceforge.net. This vulnerability is uniquely identified as CVE-2010-2448. It is possible to initiate the attack remotely. The requirement for exploitation is a authentication. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 47705 (Debian DSA-2069-1 : znc - denial of service), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 118363 (Fedora Update for ZNC (FEDORA-2010-10042)).
