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
Panasonic Security System WV-S2231L 4.25 has an insecure hard-coded password of lkjhgfdsa (which is just the asdf keyboard row in reverse order).

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

The Panasonic Security System WV-S2231L version 4.25 contains a hard-coded default password 'lkjhgfdsa' (reverse of keyboard row asdf) embedded in the firmware. This creates a backdoor that allows unauthorized attackers with knowledge of this credential to gain administrative access to the security camera system.

MitigationChange the default hard-coded password to a strong, unique credential through the device administrative interface and restrict network access to the device using firewall rules or network segmentation to prevent unauthorized attackers from reaching it.

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 device model
    Access the device web interface or check the device label/management console to confirm the exact model number is WV-S2231L
    Affected if Model is Panasonic WV-S2231L
  2. Check firmware version
    Log into the device administrative interface and navigate to System > Version or System Information page to view the installed firmware version
    Affected if Firmware version is exactly 4.25
  3. Verify default password status
    Attempt to log into the device using the default administrator username with the hardcoded password 'lkjhgfdsa', or check if the default admin account password has been changed from this default value
    Affected if Login succeeds with credentials admin/lkjhgfdsa or the password remains at default

A user is affected if they have a Panasonic WV-S2231L camera running firmware 4.25 with the default hardcoded password 'lkjhgfdsa' still active on the admin account

Mitigation

Change the default hard-coded password to a strong, unique credential through the device administrative interface and restrict network access to the device using firewall rules or network segmentation to prevent unauthorized attackers from reaching it.
