CVE-2013-1235: Cisco Wireless LAN Controller (WLC) devices do not properly address the resource consumption of terminated...

Security readout for executives and security teams

This issue can make Telnet management on Cisco Wireless LAN Controllers unavailable. The source describes a remote denial-of-service condition caused by many Telnet sessions ending improperly. It affects management access rather than wireless traffic directly, but loss of management access can delay incident response or operations. Organizations are most exposed where Cisco WLC Telnet management is enabled and reachable beyond a tightly controlled management network. Specific models and versions are not listed in the bundle. Treat this as a management-plane availability risk. It is not described as data theft or code execution, but exposed Telnet management could disrupt wireless operations support and incident response. Mitigation focus: Review Cisco Security Notice CVE-2013-1235 for affected releases and vendor remediation.; Identify Cisco WLCs with Telnet management enabled.; Restrict Telnet access to trusted management networks pending vendor guidance..
