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 ThinOS version
    Access the ThinOS admin interface or device system information. The version is typically displayed in the system settings or on the login screen as a build number.
    Affected if The installed version is 9.3.2102 or lower (versions prior to 2208).
  2. Locate log files on the device
    Using physical access to the device, navigate to the log directory. On ThinOS devices, logs are typically stored in system or diagnostic partitions accessible via recovery mode or FTP if enabled.
    Affected if Log files are present and accessible through standard or recovery boot modes.
  3. Examine log file contents for sensitive data
    Open and review the log files (such as wnos.log, system logs, or connection logs) using a text editor or command-line tool. Look for patterns indicating exposed credentials, session tokens, configuration details, or user-specific information.
    Affected if Log files contain plaintext passwords, API keys, session identifiers, or other credentials that should not be visible to unauthorized users.

A user is affected if their ThinOS version is 9.3.2102 or lower AND log files are readable, as the vulnerability allows physically accessible attackers to view sensitive information in logs.
