The Management Center for Cisco Security Agents is affected by a directory traversal vulnerability and a SQL injection vulnerability. Successful exploitation of the directory traversal vulnerability may allow an authenticated attacker to view and download arbitrary files from the server hosting the Management Center. Successful exploitation of the SQL injection vulnerability may allow an authenticated attacker to execute SQL statements that can cause instability of the product or changes in the configuration.
Additionally, the Cisco Security Agent is affected by a denial of service (DoS) vulnerability. Successful exploitation of the Cisco Security Agent agent DoS vulnerability may cause the affected system to crash. Repeated exploitation could result in a sustained DoS condition.
These vulnerabilities are independent of each other.
Cisco has released software updates that address these vulnerabilities.
This advisory is posted at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100217-csa.

The Cisco Security Agent is a security software agent that provides threat protection for server and desktop computing systems. Cisco Security Agents can be standalone agents or can be managed by the Cisco Security Agent Management Center.
The Management Center for Cisco Security Agents is affected by a directory traversal vulnerability and a SQL injection vulnerability.
Management Center for Cisco Security Agents Directory Traversal Vulnerability
The Management Center for Cisco Security Agents is affected by a directory traversal vulnerability that may allow an authenticated attacker to view and download arbitrary files from the server that is hosting the Management Center for Cisco Security Agents.
This vulnerability is documented in Cisco Bug ID CSCtd73275 ( registered customers only) and has been assigned the Common Vulnerabilities and Exposures (CVE) identifier CVE-2010-0146.
Management Center for Cisco Security Agents SQL Injection Vulnerability
The Management Center for Cisco Security Agents is also affected by a SQL injection vulnerability that may allow an authenticated attacker to execute SQL statements that can cause the Management Center for Cisco Security Agents to become unstable or modify its configuration. These configuration changes may result in modifications to the security policies of the endpoints. Additionally, an attacker may create, delete, or modify management user accounts that are found in the Management Center for Cisco Security Agents.
This vulnerability is documented in Cisco Bug ID CSCtd73290 ( registered customers only) and has been assigned the Common Vulnerabilities and Exposures (CVE) identifier CVE-2010-0147.
Cisco Security Agent Denial of service vulnerability
Cisco Security Agent is affected by a DoS vulnerability that could allow an unauthenticated attacker to cause a system to crash by sending a series of TCP packets.
Note: Only Cisco Security Agent release 5.2 is affected by the DoS vulnerability. The Windows and Sun Solaris versions of the Cisco Security Agent are not affected by the DoS vulnerability.
This vulnerability is documented in Cisco Bug ID CSCtb89870 ( registered customers only) and has been assigned the Common Vulnerabilities and Exposures (CVE) identifier CVE-2010-0148.
