CVE-2023-41183
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 · uneditedNETGEAR Orbi 760 SOAP API Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR Orbi 760 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the SOAP API. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-20524.
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 confidenceThe NETGEAR Orbi 760 router has an authentication bypass vulnerability in its SOAP API implementation. The SOAP API fails to perform authentication checks before allowing access to administrative functions, enabling network-adjacent attackers to bypass authentication entirely and gain unauthorized access to router management features.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the router modelAccess the router admin interface or check the device label/mac address to confirm the model is Netgear Rbr760 (Orbi 760)Affected if The device is not a Netgear Rbr760 unit - other models are not affected by this specific CVE
-
Check the installed firmware versionLog into the router admin interface (typically at 192.168.1.1) and navigate to Administration > Firmware Update or Advanced > Administration > Router Update to view the current firmware versionAffected if Firmware version is lower than 6.3.8.5 (e.g., 6.3.8.4, 6.3.6.5, etc.)
-
Determine if the SOAP API is network accessibleCheck if the router's SOAP service ports are exposed to the network. The SOAP API typically runs on HTTP (port 80) or HTTPS (port 443). Use a network scan (nmap -sV <router-ip> -p 80,443) or check router port forwarding/firewall settingsAffected if The SOAP API ports (80/443) are accessible from an untrusted network segment or the internet
-
Verify SOAP API authentication behaviorFrom a network-adjacent host, attempt to access a known SOAP API endpoint without credentials (e.g., curl http://<router-ip>/soap.cgi?service=DeviceInfo or check if the WSDL is accessible without login)Affected if The SOAP API responds with administrative configuration data or accepts commands without requiring authentication credentials
The environment is affected if you have a Netgear Rbr760 router running firmware version below 6.3.8.5 AND the router's SOAP API interface is accessible from your network without authentication barriers.

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.
dbcve · scoped6.3.8.5
Apply the latest NETGEAR firmware update for the Orbi 760 when available; until then, restrict network access to trusted devices only and consider network segmentation to limit exposure to adjacent attackers.
Rbr760 Firmware 6.3.8.5 or later
- Log in to the NETGEAR Orbi router web interface (typically at routerlogin.net or routerlogin.com)
- Navigate to the Administration or Settings section
- Look for Firmware Update or Manual Update option
- Download the latest firmware version 6.3.8.5 or higher from the official NETGEAR support website (kb.netgear.com)
- Upload the firmware file and wait for the update to complete
- Verify the firmware version after the update confirms successful installation
