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
Circontrol CirCarLife all versions prior to 4.3.1, the PAP credentials of the device are stored in clear text in a log file that is accessible without authentication.

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

Circontrol CirCarLife devices before version 4.3.1 store PAP (Password Authentication Protocol) credentials in clear text within a log file. This log file is accessible without any authentication, allowing remote unauthenticated attackers to obtain valid device credentials.

MitigationUpgrade CirCarLife firmware to version 4.3.1 or later to remediate the clear text credential storage. Immediately rotate all credentials that may have been exposed, as the log file was accessible without authentication.

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 CirCarLife device
    Confirm the target device is a Circontrol CirCarLife electric vehicle charging station by checking the device model, web interface, or system information
    Affected if The device is a Circontrol CirCarLife model
  2. Check firmware version
    Access the device's web interface, administrative console, or system settings to retrieve the installed firmware version. Compare this version number against the vulnerable range of < 4.3.1
    Affected if Firmware version is below 4.3.1
  3. Locate the credential log file
    Access the device's file system or log directory to find the log file referenced in the vulnerability. The vulnerability indicates a log file stores PAP credentials and is accessible without authentication
    Affected if The log file exists and is accessible without authentication
  4. Inspect for clear text credentials
    Open or retrieve the log file content and search for PAP credentials (username/password pairs) stored in plain text format rather than hashed or encrypted
    Affected if PAP credentials are present in clear text within the log file

A user is affected if they have a CirCarLife device running firmware version below 4.3.1 with accessible log files containing clear text PAP credentials

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 4.3.1 or later
Fixed in 4.3.1
Interim mitigation

Upgrade CirCarLife firmware to version 4.3.1 or later to remediate the clear text credential storage. Immediately rotate all credentials that may have been exposed, as the log file was accessible without authentication.

Recommended fix High confidence

Circontrol CirCarLife Firmware 4.3.1

  1. Identify the current firmware version of the Circontrol CirCarLife charging station
  2. Download CirCarLife firmware version 4.3.1 or later from the official Circontrol vendor
  3. Follow the vendor's standard firmware upgrade procedure, typically via the device's web interface or USB update method
  4. After upgrading, verify that the credentials are no longer stored in clear text in log files
  5. Confirm that log files are now properly protected and require authentication for access
