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 · unedited
A vulnerability of Information Exposure has been found on Technicolor CGA2121 affecting the version 1.01, this vulnerability allows a local attacker to obtain sensitive information stored on the device such as wifi network's SSID and their respective passwords.

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 confidence

Information exposure vulnerability in Technicolor CGA2121 router firmware version 1.01 allows a local attacker to retrieve stored sensitive credentials including WiFi SSIDs and their corresponding passwords from the device configuration.

MitigationApply available firmware updates from vendor; if no patch exists, implement compensating controls including network segmentation, restricting physical access to the device, and monitoring for unauthorized local access.

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 the device model
    Access the router web interface or check the device label to confirm the model is Technicolor CGA2121
    Affected if The device is a Technicolor CGA2121 router
  2. Determine the installed firmware version
    Log into the router administration panel and navigate to the firmware or status page to view the current firmware version
    Affected if The firmware version is 1.01
  3. Verify local access controls
    Check router settings to confirm who has local access to the device and whether authentication is required for accessing configuration data
    Affected if Local unauthenticated or low-privilege users can access configuration data without proper authentication
  4. Test for credential exposure
    If you have local access, attempt to retrieve configuration files or settings that contain WiFi SSIDs and passwords to verify if they are accessible without elevated privileges
    Affected if Stored WiFi SSIDs and passwords are viewable by local users without administrative credentials

The user is affected if the device is a Technicolor CGA2121 running firmware version 1.01 and local users can access stored WiFi credentials without proper authentication.
