CVE-2014-3380
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 Unified Communications Domain Manager Platform Software 4.4(.3) and earlier allows remote attackers to cause a denial of service (CPU consumption) by sending crafted TCP packets quickly, aka Bug ID CSCuo42063.
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 Unified Communications Domain Manager Platform Software versions 4.4(.3) and earlier contains a denial of service vulnerability where remote attackers can cause excessive CPU consumption by sending specially crafted TCP packets rapidly to the affected system, rendering services unavailable.

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 Unified Communications Domain Manager Platform versionAccess the system administrative interface or use the command line interface (CLI) to query the software version. Typically via 'show version' or through the web-based administration portal under System > Version information.Affected if The installed version is 4.4.3 or any earlier version (4.4, 4.3, etc.)
-
Confirm the exact version string matches affected releaseVerify the precise version number displayed matches the pattern 4.4(.3) meaning version 4.4.3 or any 4.4.x version up to and including 4.4.3, or version 4.4 without a minor release number.Affected if Version is 4.4.3, 4.4.2, 4.4.1, 4.4.0, or 4.4 (any 4.4.x release)
-
Determine if the management interface is network accessibleCheck if the Cisco Unified Communications Domain Manager Platform management TCP ports (typically 443, 8443, or other admin ports) are exposed to untrusted networks. Use network scanning or review firewall rules.Affected if The management interface is reachable from untrusted or external networks without filtering
-
Check for symptoms of TCP-based CPU exhaustionMonitor system CPU usage via 'show processes cpu history' or similar CLI command. Look for sustained high CPU consumption coinciding with inbound TCP traffic patterns.Affected if CPU utilization is abnormally high from inbound TCP traffic and services are slow or unresponsive
You are affected if the installed Cisco Unified Communications Domain Manager Platform version is 4.4.3 or any earlier 4.4.x release and the system is network-accessible to untrusted hosts.

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 Cisco security patch for bug ID CSCuo42063 to address this vulnerability. If patches are unavailable, implement network-level rate limiting or firewall controls to restrict unauthenticated TCP traffic to the affected platform.
