CVE-2021-1532
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 video endpoint API (xAPI) of Cisco TelePresence Collaboration Endpoint (CE) Software and Cisco RoomOS Software could allow an authenticated, remote attacker to read arbitrary files from the underlying operating system. This vulnerability is due to insufficient path validation of command arguments. An attacker could exploit this vulnerability by sending a crafted command request to the xAPI. A successful exploit could allow the attacker to read the contents of any file that is located on the device filesystem.

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.
-
Determine device software versionAccess the device admin interface or use the command-line interface (CLI) command 'xapi status' or check the system information page in the web interface to identify the installed Cisco CE or RoomOS version number.Affected if The installed version is less than 9.14.6, or greater than or equal to 9.15.0.11 but less than 9.15.3, or less than 10.3.1 for RoomOS variants.
-
Identify the product variantCheck whether the device is running Cisco TelePresence Collaboration Endpoint software or Cisco RoomOS software, as each has separate version ranges. This information is visible in the device web interface under 'System Information' or via CLI command.Affected if The device is a Cisco TelePresence Collaboration Endpoint or RoomOS product running any affected version.
-
Confirm xAPI accessibilityVerify that the xAPI interface (also known as the API or command-line interface) is enabled and reachable on the network. This can be confirmed by attempting to connect to the device on port 22 (SSH) or port 443 (HTTPS API), or by checking the security settings in the device admin panel.Affected if xAPI is enabled and accessible to the attacker, which is the default configuration on most devices.
-
Check for unauthorized access indicatorsReview device logs and audit records for any suspicious xAPI commands that may indicate exploitation of this path traversal vulnerability, such as requests containing '../' sequences or unexpected file read operations.Affected if Logs show anomalous xAPI file access attempts or unauthorized reads of system files.
The environment is affected if the device runs Cisco TelePresence Collaboration Endpoint CE versions < 9.14.6, >= 9.15.0.11 and < 9.15.3, or RoomOS versions < 10.3.1, with xAPI enabled and accessible.
