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 Cisco TelePresence Collaboration Endpoint (CE) Software and Cisco RoomOS Software could allow an attacker to conduct path traversal attacks, view sensitive data, or write arbitrary files on an affected device. For more information about these vulnerabilities, see the Details section of this advisory.

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 confidence

Multiple vulnerabilities in Cisco TelePresence Collaboration Endpoint (CE) Software and Cisco RoomOS Software allow path traversal attacks, unauthenticated viewing of sensitive data, and writing arbitrary files to the filesystem on affected devices. These file system vulnerabilities could enable an attacker to escape intended directory restrictions, access confidential information, and place malicious files on the device, potentially leading to broader compromise.

MitigationApply the vendor-supplied patches for affected Cisco TelePresence CE and RoomOS software versions; if patching is not immediately possible, restrict network access to management interfaces and implement network segmentation to reduce exposure.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 your device product type
    Access the device CLI and run 'show version' or use the web interface to determine if the device is running Cisco TelePresence Collaboration Endpoint (CE) Software or Cisco RoomOS Software
    Affected if The device is either Cisco TelePresence CE or Cisco RoomOS
  2. Check the installed software version
    Run 'show version' in the device CLI or check the web interface System Information page. Note the exact version number (for CE) or any version string (for RoomOS)
    Affected if For TelePresence CE: version is below 10.19.1. For RoomOS: any version is affected (all versions)
  3. Verify management interface exposure
    Check the device network configuration by running 'xconfiguration Network' or reviewing the web interface Network Settings. Determine if HTTP/HTTPS management ports are accessible from untrusted networks
    Affected if The device management interface (typically ports 80/443) is exposed to the internet or untrusted VLANs, providing an attack vector for the path traversal and file access vulnerabilities
  4. Review access logs for suspicious patterns
    Examine the device logs via 'xstatus' or the web interface Logs section. Look for unusual HTTP requests, particularly those containing '../' path traversal sequences or unusual file access patterns
    Affected if Logs show anomalous requests with path traversal characters or unauthorized access to sensitive directories

Your device is affected if it is running Cisco TelePresence CE version below 10.19.1, or any version of Cisco RoomOS, and the management interface is network-accessible to potential attackers.

Interim mitigation

Apply the vendor-supplied patches for affected Cisco TelePresence CE and RoomOS software versions; if patching is not immediately possible, restrict network access to management interfaces and implement network segmentation to reduce exposure.

Recommended fix High confidence

Cisco TelePresence Collaboration Endpoint CE software version 10.19.1 or later

  1. 1. Backup the current device configuration before initiating any upgrade
  2. 2. Download Cisco TelePresence Collaboration Endpoint software version 10.19.1 or later from the Cisco Software Download Center
  3. 3. Access the device administration interface (web UI or CLI)
  4. 4. Navigate to the software upgrade section
  5. 5. Upload and install the version 10.19.1 or later firmware
  6. 6. Verify the upgrade completed successfully and the device is functioning normally
  7. 7. Confirm the new version is running: System > Product Info in web UI or 'show version' in CLI
