CVE-2013-6684
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 web framework on Cisco Wireless LAN Controller (WLC) devices does not properly validate configuration parameters, which allows remote authenticated users to cause a denial of service via a crafted HTTP request, aka Bug ID CSCuh81011.
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 confidenceThe Cisco Wireless LAN Controller web framework fails to properly validate configuration parameters, allowing any remote authenticated user to send specially crafted HTTP requests that trigger a denial of service condition.

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.
-
Confirm Cisco WLC is in useIdentify the device model via CLI (show sysinfo) or web interface. Look for 'Wireless LAN Controller' in the device identification.Affected if Device is a Cisco Wireless LAN Controller and web management is enabled
-
Verify web management interface statusCheck via CLI: show run config | include http or show web-management status. Alternatively, check the WLC web interface is accessible on ports 80/443.Affected if HTTP/HTTPS web management is enabled and exposed
-
Confirm management access scopeReview ACLs or management interface bindings: show acl summary or show interface management. Determine if web management is reachable from untrusted networks.Affected if WLC web interface is accessible from untrusted or external networks rather than only trusted management VLANs
-
Inspect for service degradationCheck WLC operational status: show process cpu history, show client summary, show ap summary. Look for unexpected drops in client count or CPU spikes.Affected if WLC shows abnormal client disconnections, high CPU, or unresponsive web interface without known cause
-
Review HTTP request logsExamine WLC logs or syslog for unusual HTTP patterns: debug ip http all (if enabled), or external syslog collection. Look for malformed or repetitive HTTP requests.Affected if Logs show abnormal HTTP request patterns from authenticated sessions that correlate with service issues
A Cisco WLC is affected if it has web management enabled and is accessible to remote authenticated users, especially from untrusted networks, and exhibits DoS symptoms or abnormal HTTP traffic.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the relevant Cisco patch for bug CSCuh81011. Until patched, limit WLC management access to only trusted, authenticated users and monitor for abnormal HTTP request patterns.
