Details

CiscoWorks Common Services is a set of management services that are shared by network management applications in a CiscoWorks solution set.

CiscoWorks Common Services provides the foundation for CiscoWorks applications to share a common model for data storage, login, user role definitions, access privileges, security protocols, and navigation. It creates a standard user experience for all management functions. It also provides the common framework for all basic system level operations such as installation, data management (including backup-restoration and importing-exporting), event and message handling, job and process management, and software updates.

CiscoWorks Common Services for Microsoft Windows contains a vulnerability that could allow an authenticated, remote attacker to execute arbitrary commands on the affected system with the privileges of a system administrator.

The vulnerability is due to improper input validation in the CiscoWorks Home Page component. An attacker could exploit this vulnerability by sending a specially crafted URL to the affected system. An exploit could allow the attacker to execute arbitrary commands on the affected system with the privileges of a system administrator.

This vulnerability affects CiscoWorks Common Services running only on Microsoft Windows.

This vulnerability could be exploited over the default management ports, TCP port 1741 or 443.

Note: The default management ports can be reconfigured on the server.

This vulnerability is documented in Cisco bug IDs CSCtq48990, for Common Services and CiscoWorks LAN Management Solution, CSCtq63992, for Cisco Security Manager, CSCtq64011, for Cisco Unified Service Monitor, CSCtq64019, for Cisco Unified Operations Manager, CSCtr23090, for CiscoWorksQoS Policy Manager, and CSCtt25535, for CiscoWorks Voice Manager.

This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-3310.
