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
NETGEAR RAX30 GetInfo Missing Authentication Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of NETGEAR RAX30 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of SOAP requests. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to disclose sensitive information, leading to further compromise. Was ZDI-CAN-19608.

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 NETGEAR RAX30 router has an unauthenticated SOAP endpoint that exposes sensitive information. Attackers on the adjacent network can send SOAP requests to this endpoint without any credentials and retrieve sensitive configuration data, device credentials, or other confidential details that can facilitate further attacks.

MitigationApply the vendor-supplied firmware update from NETGEAR when available. Until then, restrict network access to the router's management interfaces and disable WAN-side management if possible.

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 the router model
    Check the device label or login to the router admin interface to confirm the model is NETGEAR RAX30
    Affected if The device is a NETGEAR RAX30 router and the firmware version is below 1.0.10.94
  2. Check the installed firmware version
    Log into the router admin panel and navigate to the firmware version information page, typically under Administration > Firmware Update or a similar section
    Affected if The displayed firmware version is lower than 1.0.10.94
  3. Determine if the SOAP service is accessible
    From a device on the same network as the router, attempt to access the SOAP endpoint by sending an HTTP request to the router's IP address on common HTTP ports (80/443) and observe if a SOAP or UPnP service responds
    Affected if The router responds to HTTP requests on the management interface without requiring authentication and exposes a SOAP or UPnP service
  4. Verify network exposure of management interface
    Check the router's firewall or access control settings to determine if the management interface (HTTP/HTTPS ports) is accessible from the WAN side or from adjacent networks beyond your trusted local network
    Affected if The router's management interface (HTTP/HTTPS) is reachable from network segments outside the trusted local network, enabling adjacent network attackers to reach the SOAP endpoint

If the device is a NETGEAR RAX30 running firmware version lower than 1.0.10.94 and the SOAP management interface is accessible from adjacent networks, the environment is affected by this vulnerability.

Upgrade available Upgrade to 1.0.10.94 or later
Fixed in 1.0.10.94
Interim mitigation

Apply the vendor-supplied firmware update from NETGEAR when available. Until then, restrict network access to the router's management interfaces and disable WAN-side management if possible.

Recommended fix High confidence

Rax30 Firmware version 1.0.10.94 or later

  1. Access the router's web interface by navigating to routerlogin.net or 192.168.1.1 in a web browser
  2. Log in with the router's administrator credentials
  3. Navigate to the Administration or Settings section
  4. Look for a Firmware Update or Router Update option
  5. Check for available updates and download version 1.0.10.94 or later
  6. Follow the on-screen prompts to install the firmware update
  7. Wait for the router to reboot and verify the update was successful
Caveat Firmware updates may reset some custom configurations; reconfigure any custom settings after upgrade
