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
Exposure of private personal information to an unauthorized actor, Insufficiently Protected Credentials vulnerability in Digital Operations Services Inc. WifiBurada allows Authentication Bypass. This issue affects WifiBurada: through 21052026. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

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 · moderate confidence

WifiBurada by Digital Operations Services Inc. contains an authentication bypass vulnerability that allows unauthorized actors to access the system. Due to insufficiently protected credentials, attackers can circumvent authentication controls and obtain private personal information. The vulnerability affects all versions up to the May 2021 release (21052026).

MitigationSince the vendor has not responded to disclosure attempts, organizations using WifiBurada should immediately restrict network exposure, implement additional authentication layers (such as VPN access or IP whitelisting), and audit logs for signs of unauthorized access. Consider replacing the product if no vendor patch becomes available.

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 WifiBurada installation
    Search for WifiBurada software or service in your environment using system inventory tools, running processes, or installed applications list
    Affected if WifiBurada is found running or installed in the environment
  2. Determine installed version
    Check the software version through the application interface, installed packages list, or system documentation - look for a version number or build date (the affected version format appears to be DDMMYYYY as 21052026)
    Affected if The version cannot be verified or shows 21052026 or earlier
  3. Compare version to affected range
    Compare your installed version against the affected range: versions through 21052026 are vulnerable. If your version is 21052026 or earlier, you are within the affected range
    Affected if Installed version is 21052026 or earlier (DDMMYYYY date format)
  4. Check network exposure of authentication interface
    Determine if the WifiBurada web interface or API is accessible from the network. Review firewall rules, exposed ports, and network ACLs for the system running WifiBurada
    Affected if The authentication interface is reachable from untrusted networks or the internet

Your environment is affected if WifiBurada is installed with version 21052026 or earlier and its authentication interface is network-accessible, allowing potential unauthorized access to private personal information.
