CVE-2014-3368
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 TelePresence Video Communication Server (VCS) and Expressway Software before X8.2 allow remote attackers to cause a denial of service (device reload) via a high rate of crafted packets, aka Bug ID CSCui06507.
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 confidenceCisco TelePresence Video Communication Server (VCS) and Expressway Software versions prior to X8.2 contain a denial-of-service vulnerability where remote attackers can cause device reload by sending a high rate of crafted packets. The vulnerability stems from insufficient handling of malformed network traffic.

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 Cisco VCS or Expressway installationLocate Cisco TelePresence Video Communication Server or Expressway appliances or virtual machines in your environment inventory or network topologyAffected if The device is a Cisco VCS or Expressway product
-
Determine installed software versionAccess the device admin interface or CLI and check the software version (typically found in System > Version or via 'xstatus version' command)Affected if The displayed version is X8.1 or earlier (e.g., X8.0, X7.2, etc.)
-
Compare version to affected rangeVerify that the installed version is less than or equal to X8.1Affected if Version is X8.1 or any version prior to X8.1
-
Assess network exposureDetermine if the device management interface or SIP/H.323 ports are accessible from untrusted networksAffected if The device is directly accessible from the internet or untrusted networks without filtering
Your environment is affected if you have a Cisco VCS or Expressway device running software version X8.1 or earlier that is network 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 dataUpgrade Cisco VCS and Expressway software to version X8.2 or later. If immediate patching is not feasible, implement network-level filtering or rate limiting to mitigate suspicious traffic before it reaches the affected devices.
