The Cisco Secure Services Client (CSSC) is a software client that enables customers to deploy a single authentication framework using the 802.1X authentication standard across multiple device types to access both wired and wireless networks. A lightweight version of the CSSC client is also a component of the Cisco Trust Agent (CTA) within the Cisco Network Admission Control (NAC) Framework solution. These products are affected by multiple vulnerabilities including privilege escalations and information disclosure. Cisco Security Agent (CSA) bundle versions 5.0 and 5.1 included Cisco Trust Agent software within the bundle. Customers who have deployed CTA as part of their CSA client package may be vulnerable if the version of CTA included is a version which is affected. This vulnerability does not impact the the CSA client or server software. Cisco has made free software available to address these vulnerabilities for affected customers.
