CVE-2010-2983
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe workgroup bridge (aka WGB) functionality in Cisco Unified Wireless Network (UWN) Solution 7.x before 7.0.98.0 allows remote attackers to cause a denial of service (dropped connection) via a series of spoofed EAPoL-Logoff frames, related to an "EAPoL logoff attack," aka Bug ID CSCte43374.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis vulnerability in Cisco Unified Wireless Network Solution 7.x allows remote attackers to cause denial of service by sending spoofed EAPoL-Logoff frames to the Workgroup Bridge (WGB) functionality, causing legitimate wireless connections to drop.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Cisco UWN Solution versionUse the Cisco wireless controller CLI command 'show version' or access the wireless LAN controller web interface to view the software version. Alternatively, check the system information page in the controller GUI.Affected if The installed version is 7.0 or 7.0.98.0 exactly as listed in the affected versions.
-
Confirm Workgroup Bridge (WGB) feature is enabledOn the wireless controller, use the command 'show run-config' or access the wireless settings to check if any WGB configurations exist. Look for WGB-specific interface or WLAN group settings.Affected if WGB functionality is configured or enabled on the wireless controller.
-
Check for active WGB client associationsUse the command 'show wgb summary' or 'show client summary' to view connected Workgroup Bridge clients. Check the controller GUI under Wireless > Clients.Affected if There are active WGB clients associated with the wireless network.
-
Inspect EAPoL configuration settingsReview the wireless LAN (WLAN) or radio configuration for Extensible Authentication Protocol over LAN (EAPoL) settings. Use 'show wlan' or check the WLAN security tab in the controller GUI.Affected if EAPoL authentication is enabled on WLANs that WGB clients connect to.
You are affected if your Cisco Unified Wireless Network Solution software version is exactly 7.0 or 7.0.98.0 AND the Workgroup Bridge (WGB) feature is enabled and actively handling wireless connections.
