CVE-2016-1362
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 · uneditedCisco AireOS 4.1 through 7.4.120.0, 7.5.x, and 7.6.100.0 on Wireless LAN Controller (WLC) devices allows remote attackers to cause a denial of service (device reload) via a crafted HTTP request, aka Bug ID CSCun86747.
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 · high confidenceA denial of service vulnerability exists in Cisco AireOS Wireless LAN Controller firmware versions 4.1 through 7.4.120.0, 7.5.x, and 7.6.100.0. Remote unauthenticated attackers can send a crafted HTTP request to the device management interface, causing the WLC to reload unexpectedly. This results in disruption of wireless network services for all connected clients.

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.
-
Retrieve the installed Cisco AireOS firmware versionLog into the WLC CLI and run the command 'show version' or access the web interface and check the Dashboard/Controller Summary page for the software versionAffected if The displayed version falls within 4.1 through 7.4.120.0, any 7.5.x version, or 7.6.100.0
-
Verify the management interface is enabled and accessibleCheck WLC configuration via 'show management' CLI command or review the web interface under Controller > Management > HTTP/HTTPS to confirm the management web server is enabledAffected if HTTP or HTTPS management access is enabled, exposing the interface to network traffic
-
Confirm network exposure of the management interfaceReview access control lists and interface bindings using 'show run-config' or check which interfaces have management IP addresses assigned, particularly looking at the AP-manager and management VLANsAffected if The management interface IP is reachable from untrusted networks or the management VLAN is not properly segmented
-
Identify any existing ACLs filtering management trafficRun 'show acl summary' or review the management access list configuration to determine if HTTP/HTTPS traffic to the WLC is restrictedAffected if No ACLs are applied to block or restrict management interface access, leaving it open to unauthenticated requests
You are affected if your Cisco AireOS version is 4.1 through 7.4.120.0, 7.5.x, or 7.6.100.0 AND the management interface is network-accessible without restriction.
Generated from the published advisory. Verify against your own configuration.
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 security patch for this vulnerability (refer to Cisco bug ID CSCun86747). Until patched, restrict management interface access to trusted networks using ACLs or VPNs, and monitor for unusual HTTP traffic patterns.
