Lifecycle Timeline
3DescriptionCVE.org
A vulnerability has been found in TRENDnet TEW-432BRP 3.10B20. This impacts the function formSetRoute of the file /goform/formSetRoute. The manipulation of the argument ip/mask/gateway leads to command injection. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. The vendor explains: "This product has been EOL for 15 years (since 2009). As the item has been EOL for such a long time, we are not able to replicate or fix any vulnerabilities." This vulnerability only affects products that are no longer supported by the maintainer.
AnalysisAI
Command injection in TRENDnet TEW-432BRP firmware 3.10B20 allows network-reachable authenticated attackers to execute arbitrary OS commands by injecting shell metacharacters into the ip, mask, or gateway parameters of the formSetRoute CGI handler at /goform/formSetRoute. A public proof-of-concept exploit has been disclosed on GitHub. No patch will ever be released - TRENDnet has explicitly confirmed the device reached end-of-life in 2009 and is unable to replicate or remediate the vulnerability, making permanent residual risk the defining characteristic of this CVE.
Technical ContextAI
The TRENDnet TEW-432BRP is a consumer wireless router with firmware 3.10B20, identified by CPE cpe:2.3:a:trendnet:tew-432brp:*:*:*:*:*:*:*:*. The vulnerable code path is the formSetRoute CGI handler at /goform/formSetRoute, a form-processing routine common to embedded router firmware that handles IPv4 routing table configuration. CWE-77 (Improper Neutralization of Special Elements used in a Command) identifies the root cause: user-supplied values for ip, mask, and gateway parameters are passed unsanitized into a downstream shell invocation - likely a system() or popen() call - without stripping or escaping shell metacharacters. This pattern is endemic to legacy embedded firmware built without modern input validation libraries, and is particularly dangerous in routing configuration handlers that inherently interact with OS-level networking commands.
RemediationAI
No vendor-released patch exists and none will ever be provided - TRENDnet has explicitly confirmed this product has been end-of-life since 2009 and cannot issue a fix. The primary and only durable remediation is device replacement with a currently supported router model. As immediate compensating controls pending replacement: restrict access to the router's web management interface (typically TCP 80/443) using upstream firewall rules to limit reachability to trusted management hosts only, which reduces exposure but does not eliminate risk for internally-positioned attackers who already hold low-privilege credentials. Disabling any remote management or WAN-side web interface features reduces the network-accessible attack surface. Rotating or hardening router credentials limits the PR:L exploitation prerequisite. All compensating controls are inherently temporary mitigations and do not substitute for retiring this hardware.
