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 SOAP Request SQL Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of specific SOAP requests. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the service account. Was ZDI-CAN-19754.

dbcve analysis · high confidence

SQL injection vulnerability in NETGEAR RAX30 router SOAP request handling. The router fails to validate user-supplied strings before using them in SQL queries, allowing unauthenticated attackers to inject malicious SQL. This can be chained with other vulnerabilities to achieve remote code execution.

MitigationApply NETGEAR firmware update when available; until then, restrict network access to the router's management interface and disable SOAP services if not required.

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 router model
    Access the router's web administration interface (typically at 192.168.1.1) and navigate to the Administration or Advanced settings to view the device model, or physically inspect the device label.
    Affected if The model is RAX30, RAXE300, RAX40, RAX35, or RAX38.
  2. Check installed firmware version
    In the router's web interface, go to Administration > Firmware Update or Advanced > Administration > Router Status to view the current firmware version number.
    Affected if The firmware version is lower than 1.0.10.94 (for example, 1.0.10.93 or earlier).
  3. Verify SOAP service availability
    Attempt to access the router's SOAP endpoint by sending an HTTP POST request to the SOAP service URL (commonly /soap/server.php or /soap.cgi on the router's LAN IP). A response indicates the service is running.
    Affected if The SOAP service responds to requests, meaning it is enabled and reachable.
  4. Confirm SOAP service exposure to network
    From an external host on a different network segment, attempt to reach the router's SOAP endpoint via its WAN IP. If the request succeeds, the service is externally accessible.
    Affected if The SOAP service is reachable from outside the local network.

The router is affected if it is one of the listed models (RAX30, RAXE300, RAX40, RAX35, RAX38) running firmware below version 1.0.10.94, and the SOAP service is enabled and accessible on the network.

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

Apply NETGEAR firmware update when available; until then, restrict network access to the router's management interface and disable SOAP services if not required.

Recommended fix High confidence

Firmware version 1.0.10.94 or later for RAX30, Raxe300, Rax40, Rax35, and Rax38

  1. 1. Identify your router model number (RAX30, Raxe300, Rax40, Rax35, or Rax38)
  2. 2. Visit the official NETGEAR support page at kb.netgear.com
  3. 3. Navigate to the Downloads/Support page for your specific router model
  4. 4. Download the firmware version 1.0.10.94 or later
  5. 5. Access your router's web management interface via a browser at routerlogin.net or 192.168.1.1
  6. 6. Navigate to the Administration > Firmware Update section
  7. 7. Select the downloaded firmware file and initiate the update
  8. 8. Wait for the router to reboot and confirm the update was successful
Caveat Standard router firmware update - ensure stable power during upgrade; default settings may be retained or reset per NETGEAR update process
