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
Multiple vulnerabilities in the video service of Cisco TelePresence Collaboration Endpoint (CE) and Cisco RoomOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by sending crafted traffic to the video service of an affected endpoint. A successful exploit could allow the attacker to cause the video service to crash, resulting in a DoS condition on an affected device.

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

Multiple input validation vulnerabilities in the video service of Cisco TelePresence Collaboration Endpoint (CE) and RoomOS Software allow unauthenticated remote attackers to crash the video service by sending specially crafted traffic, resulting in denial of service.

MitigationApply Cisco's security updates for the affected CE and RoomOS software versions. Restrict network access to the video service to trusted sources as a compensating control until patches can be applied.

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 and software version
    Access the admin interface or use the command 'xstatus systemunit' or check the version through the web UI under 'Home > System Information'
    Affected if The device is running Cisco RoomOS (all versions) or Cisco TelePresence Collaboration Endpoint version below 9.8.0
  2. Verify the video service is enabled
    Check through the admin interface under 'Configuration > Video > Input/Output' or use command 'xCommand Video Input List' to confirm video services are configured
    Affected if Video service is active and the device is in the affected version range
  3. Check network exposure of the video service
    Review firewall rules or access lists that allow external traffic to reach the video service ports (typically 5060/5061 for SIP, or RTSP ports)
    Affected if The video service is accessible from untrusted networks and the device version is affected
  4. Look for service crash indicators
    Monitor logs via 'xCommand SystemLogs Diagnostic' or check the web UI status page for unexpected video service restarts or downtime
    Affected if Video service crashes occur without corresponding updates or known issues, and version is within affected range

The environment is affected if the device runs Cisco RoomOS (any version) or Cisco TelePresence Collaboration Endpoint software version below 9.8.0 and has its video service exposed to network traffic.
