CVE-2014-2159
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 H.225 subsystem in Cisco TelePresence System MXP Series Software before F9.3.1 allows remote attackers to cause a denial of service (device reload) via crafted packets, aka Bug ID CSCtq78722.
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 confidenceDenial of service vulnerability in the H.225 signaling protocol subsystem of Cisco TelePresence System MXP Series devices. Remote attackers can send crafted H.225 packets to trigger an uncontrolled reload of the device, causing service disruption.

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 modelRun 'show system' or 'show version' command on the Cisco TelePresence device to confirm it is an MXP Series device (2000 Mxp, 550 Mxp, 770 Mxp, 880 Mxp, 990 Mxp, 1000 Mxp, or 1700 Mxp)Affected if The device is any Cisco Tandberg MXP or Cisco Telepresence System MXP model
-
Check the installed software versionExecute 'show version' or 'show software' command to retrieve the current firmware version installed on the deviceAffected if The software version is <= f9.3, or exactly f9.0.1, f9.0.2, f9.1.0, f9.1.1, f9.1.2, fnc9.1.0, fnc9.1.1, fnc9.1.2, or fnc9.3
-
Verify H.225 protocol subsystem is activeCheck the device signaling configuration via 'show call control' or 'show h225' command to determine if H.225 (part of H.323 protocol stack) is enabled and used for VoIP/telepresence callsAffected if H.225 signaling protocol is enabled and the device accepts H.323-based calls
-
Confirm H.323 gateway configurationInspect 'show gateway' or 'show h323' configuration to see if the device is configured as an H.323 gateway or endpoint accepting H.225 signalingAffected if The device is configured as an H.323 gateway or endpoint accepting incoming H.225 signaling connections
The device is affected if it is a Cisco TelePresence MXP Series device running software version f9.3 or earlier (or any of the specific listed versions) with H.225 signaling protocol enabled.
