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) and RoomOS software allow path traversal attacks, enabling attackers to view sensitive data and write arbitrary files on affected devices. The combination of information disclosure and arbitrary file write capabilities makes this particularly dangerous as it could lead to complete device compromise.

MitigationApply Cisco's patches for affected software versions; restrict network access to collaboration endpoints and monitor for unauthorized file access or modification attempts.

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 device model and software version
    Access the device web interface and navigate to the About page, or connect via SSH and run the 'xStatus SystemUnit Software' command
    Affected if The installed version falls within >= 9.0.0.0 and < 9.15.13.0, OR >= 10.0.0.0 and < 10.15.2.2 for Cisco TelePresence Collaboration Endpoint, OR < 10.15.1 for Cisco RoomOS
  2. Verify web interface is accessible
    Attempt to reach the device HTTP/HTTPS web interface from a network location
    Affected if The web interface responds and is reachable - this is the primary attack vector for the path traversal vulnerability
  3. Confirm API or file transfer services are enabled
    Check if the device has HTTP file upload, API endpoints, or FTP/SFTP services enabled via 'xConfiguration' commands or the web interface
    Affected if These services are enabled and exposed, allowing the arbitrary file write portion of the attack to succeed
  4. Review recent file access logs
    Examine system logs via the web interface or 'xFeedback' events for unusual file access patterns, especially attempts to access system directories outside the web root
    Affected if Logs show access to paths like '../' or attempts to traverse outside expected directories

The device is affected if it runs an unpatched Cisco TelePresence CE or RoomOS version within the affected ranges AND has its web interface or API services exposed on the network.

Upgrade available Upgrade to 9.15.13.0 / 10.15.1 / 10.15.2.2 or later
Fixed in 9.15.13.010.15.110.15.2.2
Interim mitigation

Apply Cisco's patches for affected software versions; restrict network access to collaboration endpoints and monitor for unauthorized file access or modification attempts.

Recommended fix High confidence

Telepresence CE: upgrade to 9.15.13.0 or later, or 10.15.2.2 or later; RoomOS: upgrade to 10.15.1 or later

  1. 1. Determine the current software version by accessing the web interface of the Telepresence device and navigating to Settings > Version, or by using the CLI command 'xversion'
  2. 2. Identify the product model: for Telepresence Collaboration Endpoint (CE) devices, note whether the current version starts with 9.x or 10.x; for RoomOS devices, note the version number
  3. 3. If running Telepresence CE version 9.x (9.0.0.0 through 9.15.12.x), download Cisco Telepresence CE version 9.15.13.0 or later from the Cisco Software Download center
  4. 4. If running Telepresence CE version 10.x (10.0.0.0 through 10.15.2.1), download Cisco Telepresence CE version 10.15.2.2 or later from the Cisco Software Download center
  5. 5. If running RoomOS (any version below 10.15.1), download Cisco RoomOS version 10.15.1 or later from the Cisco Software Download center
  6. 6. Upload the firmware file through the device web interface under Maintenance > Software Upgrade, or via CLI using the command 'software upgrade <filename>'
  7. 7. After upgrade completes, verify the new version by checking Settings > Version or using 'xversion' command
