CVE-2010-2841: Unspecified vulnerability in Cisco Wireless LAN Controller (WLC) software 4.2 before 4.2.209.0; 4.2M before...

Security readout for executives and security teams

This issue affects older Cisco Wireless LAN Controller software. An authenticated remote user could send malformed HTTP traffic to the controller management component and cause the device to reload, disrupting wireless service. The source bundle does not provide a CVSS score or evidence of active exploitation. Exposure is most likely where affected Cisco WLC versions remain in service and HTTP management is reachable by authenticated users. Internet or broad internal access to the management plane would increase business impact. Treat as a maintenance and resilience priority, especially for sites dependent on wireless connectivity. Urgency increases if old WLC management interfaces are broadly reachable or shared among many administrators. Mitigation focus: Upgrade Cisco WLC software to the fixed release for the deployed branch.; Consult Cisco advisory guidance before changing controller management settings.; Restrict WLC management HTTP access to trusted administrative networks..
