CVE-2013-1141: The mDNS snooping functionality on Cisco Wireless LAN Controller (WLC) devices with software 7.4.1.54 and e...

Security readout for executives and security teams

This vulnerability can let an authenticated remote user crash affected Cisco Wireless LAN Controller devices, causing a device reload. The business impact is wireless service disruption, not documented data theft or code execution. The source bundle does not provide CVSS scoring or fixed-version details. Exposure is likely limited to Cisco WLC deployments running software 7.4.1.54 or earlier where authenticated users can send traffic reaching the mDNS snooping functionality. Public source details do not identify broader product families, unauthenticated exposure, or cloud exposure. Prioritize remediation for environments where wireless availability is business-critical or many users depend on affected controllers. The issue is an authenticated denial-of-service risk, so urgency is lower than unauthenticated remote compromise but still material for operations. Mitigation focus: Identify Cisco WLC devices running software 7.4.1.54 or earlier.; Review Cisco’s advisory for fixed releases or supported workarounds.; Limit authentication access to wireless infrastructure where feasible..
