CVE-2022-20931
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 · uneditedA vulnerability in the version control of Cisco TelePresence CE Software for Cisco Touch 10 Devices could allow an unauthenticated, adjacent attacker to install an older version of the software on an affected device. This vulnerability is due to insufficient version control. An attacker could exploit this vulnerability by installing an older version of Cisco TelePresence CE Software on an affected device. A successful exploit could allow the attacker to take advantage of vulnerabilities in older versions of the software.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
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 confidenceThis vulnerability in Cisco TelePresence CE Software for Touch 10 devices allows an unauthenticated attacker on the adjacent network to install an older software version on affected devices. The issue stems from insufficient version control mechanisms that fail to prevent software downgrades. An attacker could exploit this to revert to a vulnerable software version containing known CVEs.

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 the installed Cisco TelePresence CE Software versionAccess the device admin interface or use the command 'xstatus systemunit' via the API/CLI to retrieve the current software versionAffected if The installed version is below 10.15.2.2 (the device is already running a vulnerable version that could be further downgraded)
-
Verify if downgrade protection is enforcedCheck the device configuration for any software version validation settings using 'xConfiguration SystemUnit Software Upgrade' or review admin security settingsAffected if No version control or downgrade protection is configured, allowing any software version to be installed regardless of age
-
Determine network accessibility of the Touch 10 deviceAssess whether the device management interface is reachable from the adjacent network (check IP accessibility and firewall rules on ports used for device management/API)Affected if The device management interface is accessible from an unauthenticated adjacent network attacker
-
Review software installation history if availableCheck device logs or audit trails for any recent software version changes using 'xHistory' command or system logsAffected if Evidence exists of unexpected software version changes indicating potential downgrade activity
The user is affected if the device allows software downgrades (either because it runs version < 10.15.2.2 or lacks version control mechanisms to prevent installing older software images) and is accessible from an adjacent network.

dbcve · scoped10.15.2.2
Apply the Cisco software updates released to address this vulnerability. There are no available workarounds; the only remediation path is patching to a secure version.
Cisco TelePresence CE Software version 10.15.2.2 or later
- 1. Identify the current Cisco TelePresence CE Software version running on the Touch 10 device by accessing the device admin interface or using the appropriate CLI command.
- 2. Navigate to the Cisco Software Download page (software.cisco.com) and locate Cisco TelePresence CE Software version 10.15.2.2 or later for your specific device model.
- 3. Download the appropriate software image for your TelePresence device.
- 4. Review Cisco's upgrade instructions for TelePresence CE Software to ensure proper installation procedure is followed.
- 5. Upload the new software image to the device through the admin interface or CLI.
- 6. Initiate the software upgrade following Cisco's documented upgrade process.
- 7. After upgrade completes, verify the device is running version 10.15.2.2 or later by checking the software version in the admin interface or CLI.
