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. Confirm Apache Traffic Server is installed
    Run 'traffic_server -V' or check for the traffic_server binary in standard paths like /usr/bin/traffic_server or /usr/local/bin/traffic_server
    Affected if If the command fails or the binary is not found, Apache Traffic Server is not present and this CVE does not apply
  2. Extract the installed version number
    Execute 'traffic_server -V' and note the version output (format typically shows major.minor.patch, e.g., 9.2.5 or 10.0.1)
    Affected if The version number is required to determine if it falls within the affected ranges
  3. Compare version against affected range 9.x
    Check if the installed version is >= 9.0.0 and < 9.2.9 (vulnerable versions are 9.0.0 through 9.2.8)
    Affected if If version matches this range, the installation is affected by this improper input validation vulnerability
  4. Compare version against affected range 10.x
    Check if the installed version is >= 10.0.0 and < 10.0.4 (vulnerable versions are 10.0.0 through 10.0.3)
    Affected if If version matches this range, the installation is affected by this improper input validation vulnerability

A system is affected if Apache Traffic Server is installed and its version is either 9.0.0-9.2.8 or 10.0.0-10.0.3
