CVE-2007-2037: Cisco Wireless LAN Controller (WLC) before 3.2.116.21, and 4.0.x before 4.0.155.0, allows remote attackers...

Security readout for executives and security teams

This vulnerability can let an attacker already on the local network crash affected Cisco Wireless LAN Controllers. A crash can disrupt wireless service, making this primarily an availability risk for organizations still running very old WLC software. Exposure is most likely in legacy environments with Cisco WLC software from the affected 3.2 or 4.0 branches still deployed and reachable from local network segments. Treat this as a legacy infrastructure availability issue. It is not documented here as actively exploited, but an unpatched controller could be crashed by a local-network attacker and disrupt wireless operations. Mitigation focus: Upgrade affected Cisco WLC software to 3.2.116.21, 4.0.155.0, or later applicable vendor guidance.; Review the Cisco advisory for model-specific fixes and operational caveats.; Reduce untrusted local-network reachability to wireless controller infrastructure where possible..
