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
In WODESYS WD-R608U router (also known as WDR122B V2.0 and WDR28) due to lack of authentication in the configuration change module in the adm.cgi endpoint, the unauthenticated attacker can execute commands including backup creation, device restart and resetting the device to factory settings. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version WDR28081123OV1.01 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

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 WODESYS WD-R608U router (models WDR122B V2.0 and WDR28) contains an authentication bypass vulnerability in the adm.cgi endpoint's configuration change module. An unauthenticated attacker can execute arbitrary commands including creating device backups, restarting the router, and resetting to factory settings due to the complete absence of authentication checks.

MitigationSince no vendor patch is available, implement compensating controls such as restricting network access to the device's management interface via firewall rules or network segmentation. If the device is no longer supported, consider replacement with a currently maintained product.

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
    Check the router's web interface status page, device label, or boot logs for the model number. Look for WODESYS WD-R608U, WDR122B V2.0, or WDR28.
    Affected if The device is a WODESYS WD-R608U router (models WDR122B V2.0 or WDR28)
  2. Verify adm.cgi endpoint exists
    Access the router's web interface and navigate to adm.cgi, or attempt a GET request to http://[router-ip]/cgi-bin/adm.cgi
    Affected if The adm.cgi endpoint is present and responds to requests
  3. Test authentication requirement on configuration functions
    Attempt to access configuration change functions via adm.cgi without providing any login credentials. This includes triggering actions like backup creation, router restart, or factory reset through direct HTTP requests to the endpoint.
    Affected if Configuration and management functions in adm.cgi execute without requiring any authentication credentials
  4. Check network exposure of management interface
    Determine if the router's web management interface (port 80/443) is directly accessible from untrusted networks such as the internet, rather than only from a trusted internal network.
    Affected if The router's management interface is exposed to untrusted networks without firewall protection

You are affected if you operate a WODESYS WD-R608U router (WDR122B V2.0 or WDR28) where the adm.cgi endpoint allows unauthenticated access to configuration change functions.

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.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Since no vendor patch is available, implement compensating controls such as restricting network access to the device's management interface via firewall rules or network segmentation. If the device is no longer supported, consider replacement with a currently maintained product.
