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 · unedited
Cisco TelePresence Video Communication Server with software before X7.0.1 allows remote attackers to cause a denial of service (device crash) via a malformed SIP message, aka Bug ID CSCtr20426.

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 confidence

Cisco TelePresence Video Communication Server versions before X7.0.1 contain a denial of service vulnerability where malformed SIP (Session Initiation Protocol) messages sent by remote attackers can cause the device to crash.

MitigationUpgrade Cisco TelePresence VCS software to version X7.0.1 or later to patch the vulnerability.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed product
    Log into the Cisco TelePresence device and run 'version' or check the admin web interface for the product name and model
    Affected if Product is Cisco TelePresence Video Communication Server or Cisco Telepresence System Software (versions x5.2, x6.0, x6.1, or x7.0 and below)
  2. Determine the software version
    Execute 'version' command in CLI or check System > Software version in the web admin interface
    Affected if Version is below X7.0.1 (including all x5.2, x6.0, x6.1, and x7.0 versions)
  3. Verify SIP is enabled
    Check Configuration > Protocols > SIP in the web admin interface, or run 'show sip' in CLI
    Affected if SIP protocol is enabled and reachable from network (the malformed SIP messages must be able to reach the device)
  4. Check device accessibility
    Ping the VCS IP address and verify SIP port 5060 is listening using 'show port 5060' or a network scanner
    Affected if Device is network-accessible and SIP port is open to untrusted networks

Affected if the device is running Cisco TelePresence VCS or Telepresence System Software version X7.0.1 or earlier and has SIP protocol enabled and network-accessible.
