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
KuWFi 5G01-X55 FL2020_V0.0.12 devices expose an unauthenticated API endpoint (ajax_get.cgi), allowing remote attackers to retrieve sensitive configuration data, including admin credentials.

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

KuWFi 5G01-X55 FL2020_V0.0.12 devices expose an unauthenticated API endpoint at ajax_get.cgi that allows remote attackers to retrieve sensitive configuration data, including plaintext admin credentials, without any authentication required.

MitigationRestrict network access to the device's management interface and apply any available firmware update from the vendor to patch the unauthenticated endpoint vulnerability.

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 to confirm it is a KuWFi 5G01-X55 model
    Affected if Device is a KuWFi 5G01-X55 unit
  2. Check firmware version
    Log into the device admin panel and navigate to the status or system information page to view the firmware version, or use the command 'cat /proc/version' or 'cat /etc/version' via telnet/SSH if available
    Affected if Firmware version is FL2020_V0.0.12 or falls within the affected range
  3. Verify ajax_get.cgi is accessible without authentication
    Send an HTTP GET request to http://<device_ip>/cgi-bin/ajax_get.cgi without providing any authentication headers or credentials
    Affected if The endpoint responds with HTTP 200 and returns data without requiring login
  4. Confirm sensitive data exposure
    Examine the response from the unauthenticated ajax_get.cgi request and look for plaintext admin usernames and passwords within the returned configuration data
    Affected if The response contains plaintext admin credentials or other sensitive configuration information without authentication

The device is affected if it is a KuWFi 5G01-X55 running firmware FL2020_V0.0.12 and the ajax_get.cgi endpoint returns sensitive data including plaintext admin credentials without any authentication.

Mitigation

Restrict network access to the device's management interface and apply any available firmware update from the vendor to patch the unauthenticated endpoint vulnerability.
