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
Belkin 54G (F5D7130) wireless router allows remote attackers to access restricted resources by sniffing URIs from UPNP datagrams, then accessing those URIs, which do not require authentication.

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 Belkin 54G (F5D7130) wireless router's UPnP implementation exposes administrative URIs in broadcasted datagrams without requiring authentication. An attacker on the local network can sniff these URIs and directly access restricted router resources, bypassing authentication entirely.

MitigationReplace the deprecated Belkin 54G router with a current model that receives security updates, as this legacy device cannot be patched for this vulnerability.

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
    Log into the router's web administration interface (typically at 192.168.2.1) and check the device status or system info page to confirm the model number is F5D7130 (Belkin 54G)
    Affected if The router model is Belkin 54G (F5d7130)
  2. Verify UPnP is enabled
    In the router's web admin interface, navigate to the UPnP settings page (usually under Advanced or LAN settings) and check whether the UPnP checkbox is enabled or the feature is turned on
    Affected if UPnP is enabled on the router - this is the vulnerable feature that broadcasts administrative URIs
  3. Confirm network accessibility
    Determine if untrusted devices can connect to the local network (wired or wireless) - an attacker would need to be on the same network segment to sniff the UPnP broadcast packets
    Affected if Untrusted or unknown devices can access the local network where the router is deployed
  4. Inspect UPnP broadcast traffic
    Use a network packet capture tool (such as Wireshark) on a computer connected to the router's network and filter for UPnP multicast traffic (typically to 239.255.255.250 on port 1900) to observe if administrative URIs are being broadcast without authentication
    Affected if UPnP datagrams contain administrative URIs (such as /router.config, /WLAN.config, or similar) that do not require credentials to access

You are affected if you are using a Belkin 54G (F5D7130) router with UPnP enabled, as administrative URIs are broadcast without authentication and can be accessed by anyone on the local network.
