CVE-2016-1479
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 IP Phone 8800 devices with software 11.0(1) allow remote attackers to cause a denial of service (memory corruption) via a crafted HTTP request, aka Bug ID CSCuz03038.
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 confidenceCisco IP Phone 8800 devices running software version 11.0(1) contain a memory corruption vulnerability in HTTP request handling. Remote attackers can send crafted HTTP requests to cause denial of service via memory corruption, likely due to improper bounds checking in the HTTP parsing routine.

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 the device modelAccess the phone's web interface or check the device label to confirm it is a Cisco IP Phone 8800 Series deviceAffected if Device is not a Cisco IP Phone 8800 Series - not affected
-
Check the firmware versionNavigate to the phone's web interface (Settings > Device Settings > Firmware Versions) or use the Cisco Unified Communications Manager admin page to view the current firmware versionAffected if Firmware version is not 11.0(1) - not affected
-
Verify HTTP management is enabledCheck the phone's web interface under Administration > Web Server or Settings > HTTP Server to confirm the embedded web server for HTTP management is enabledAffected if HTTP management is disabled - vulnerability cannot be triggered
-
Check network accessibility of HTTP interfaceDetermine if the phone's HTTP management port (typically 80 or 443) is exposed to untrusted networks by reviewing firewall rules, VLAN configuration, or network accessibility scansAffected if HTTP management is only accessible from trusted management networks - reduced risk but still affected if version matches
Device is affected if it is a Cisco IP Phone 8800 Series running firmware version 11.0(1) with HTTP management interface enabled and accessible.

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 firmware update for the IP Phone 8800 series that addresses CSCuz03038. As an interim measure, restrict or disable HTTP management access on vulnerable devices and place them behind firewalls.
