This section provides details on affected products.
Vulnerable Products
All Cisco products and applications that are using Microsoft IIS are considered vulnerable.
To determine if a product is vulnerable, review the list below. If the software versions or configuration information are provided, then only those combinations are vulnerable.
-
Cisco CallManager 3.0, 3.1, 3.2
-

-
Cisco Collaboration Server (CCS)
-
Cisco Dynamic Content Adapter (DCA)
-

Various Cisco Network Management products may be installed on Microsoft platforms that may be running a vulnerable version of IIS. Much older versions of CiscoWorks 2000 RWAN/CWSI Campus v2.x and Cisco Voice Manager v1.x are directly vulnerable because IIS was required as a part of the installation. Such systems might be offering HTTP services on default ports. These specific software packages are no longer supported, but are included in this notice to alert customers who might still be using them.
Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected by these vulnerabilities.
-
