A vulnerability was found in Cisco CallManager up to 4.1 (Unified Communication Software). It has been declared as problematic. Affected by this vulnerability is some unknown functionality of the file /CCMAdmin/serverlist.asp of the component Web Interface. The manipulation of the argument pattern with the input value <img%20src='http://www.scip.ch/scip.gif'%20style='border:%201px%20solid%20black;'> leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. As an impact it is known to affect confidentiality, and integrity. The summary by CVE is:

Cross-site scripting (XSS) vulnerability in the web application firewall in Cisco CallManager before 3.3(5)sr3, 4.1 before 4.1(3)sr5, 4.2 before 4.2(3)sr2, and 4.3 before 4.3(1)sr1 allows remote attackers to inject arbitrary web script or HTML via the pattern parameter to CCMAdmin/serverlist.asp (aka the search-form) and possibly other unspecified vectors.

The weakness was disclosed 05/23/2007 by Marc Ruef and Stefan Friedli with scip AG as Cisco CallManager 4.1 Input Validation Vulnerability as confirmed advisory (Website). The advisory is shared at scip.ch. The public release has been coordinated in cooperation with Cisco. This vulnerability is known as CVE-2007-2832 since 05/23/2007. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction.

A public exploit has been developed by Marc Ruef/Stefan Friedli in URL/Javascript and been published immediately after the advisory. It is possible to download the exploit at scip.ch. It is declared as highly functional. We expect the 0-day to have been worth approximately $5k-$25k. By approaching the search of inurl:CCMAdmin/serverlist.asp it is possible to find vulnerable targets with Google Hacking.
