CVE-2013-7293
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 · uneditedThe ASUS WL-330NUL router has a configuration process that relies on accessing the 192.168.1.1 IP address, but the documentation advises users to instead access a DNS hostname that does not always resolve to 192.168.1.1, which makes it easier for remote attackers to hijack the configuration traffic by controlling the server associated with that hostname.
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 · moderate confidenceThe ASUS WL-330NUL router configuration process relies on users accessing a DNS hostname provided in documentation rather than the hardcoded IP address 192.168.1.1. Since this hostname does not reliably resolve to the intended router IP, an attacker who controls the DNS resolution path can redirect users to a malicious server and intercept configuration traffic.

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 modelCheck the device label or administrative interface to confirm the model is ASUS WL-330NULAffected if The device is an ASUS WL-330NUL router (all versions are affected)
-
Determine how you access the router admin interfaceReview your bookmarks, scripts, or documentation to see if you use a DNS hostname (such as router.asus.com or similar documented hostname) to reach the configuration interface at 192.168.1.1Affected if You access the router via a DNS hostname rather than directly via the IP address 192.168.1.1
-
Verify DNS resolution for the router hostnameFrom a client device on the network, perform a DNS lookup (nslookup or dig) on the hostname provided in the ASUS documentation for this router and compare the resolved IP to 192.168.1.1Affected if The DNS hostname resolves to an IP address other than 192.168.1.1, or resolution is inconsistent or controlled by an untrusted party
-
Check for DNS hijacking exposureInspect your network configuration to determine if DNS queries for the router hostname could be intercepted or modified by an upstream ISP DNS server or intermediate network deviceAffected if You rely on DNS servers outside your direct control and do not have DNSSEC or local DNS validation enabled
You are affected if you use the ASUS WL-330NUL and access its configuration interface via a DNS hostname instead of directly using 192.168.1.1, leaving you vulnerable to DNS hijacking attacks.

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 dataUsers should access the router configuration interface directly via the IP address 192.168.1.1 instead of the documented DNS hostname. Network operators should also implement DNSSEC or local DNS controls to prevent DNS hijacking.
