CVE-2022-20776
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 · uneditedMultiple 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 · high confidenceMultiple vulnerabilities in Cisco TelePresence Collaboration Endpoint (CE) and RoomOS Software allow path traversal attacks, unauthorized access to sensitive data, and writing arbitrary files to the device's filesystem. These file handling vulnerabilities in the web interface or API components enable attackers to escape intended directory restrictions.

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.
-
Check installed software versionAccess the device admin interface or use the command 'xStatus' via the API to retrieve the current software version. Alternatively, log in to the device and run 'systemunit version' or check the about page in the web interface.Affected if The installed version is Cisco TelePresence CE or RoomOS below version 10.20.1
-
Verify web interface statusLog into the device command line (SSH or serial) and run the command 'xConfiguration Httpd Mode' to check if the built-in HTTP server is enabled.Affected if The HTTP/HTTPS web interface is enabled (mode is ON) on a version below 10.20.1
-
Check API accessibilityRun 'xConfiguration Httpd Api Mode' to verify whether the device API (HTTP/HTTPS) is accessible.Affected if The API is enabled and accessible on a version below 10.20.1
-
Review network exposureCheck the device network configuration using 'xConfiguration Network 1' or review the firewall rules to determine if management ports (80, 443, 22) are reachable from untrusted networks.Affected if Management interfaces are exposed to untrusted networks and the software version is below 10.20.1
A user is affected if the device runs Cisco TelePresence CE or RoomOS software version below 10.20.1 and has the web interface or API enabled and accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped10.20.1
Apply the vendor-supplied firmware/software updates referenced in the Cisco advisory to remediate these vulnerabilities. Restrict network access to management interfaces to trusted sources.
Cisco RoomOS/Telepresence CE version 10.20.1
- 1. Identify all affected Cisco TelePresence Collaboration Endpoint and RoomOS devices in your inventory
- 2. Review the current software version on each device using the web interface or CLI command: 'xStatus systemUnit'
- 3. Download Cisco RoomOS software version 10.20.1 or later from the Cisco Software Download Center (requires valid Cisco service contract)
- 4. Upload the new software image to each affected device via the web interface (Administration > Software Upgrade) or via CLI using 'file put' command
- 5. Initiate the upgrade and allow the device to reboot into the new version
- 6. After reboot, verify the new version is installed by running 'xStatus systemUnit' and confirming the software version is 10.20.1 or later
- 7. Verify that affected functionality continues to operate normally post-upgrade
