DescriptionCVE.org

A security vulnerability has been detected in TRENDnet TEW-432BRP 3.10B20. Affected by this issue is the function formSetEnableWizard of the file /goform/formSetEnableWizard. Such manipulation of the argument start_wizard leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed publicly 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

Stack-based buffer overflow in TRENDnet TEW-432BRP 3.10B20 wireless router allows authenticated remote attackers to corrupt memory via the start_wizard parameter in the /goform/formSetEnableWizard endpoint. Publicly available exploit code exists, and the vendor has confirmed they will not issue a fix because the device has been end-of-life since 2009. EPSS data was not provided, and the CVE is not listed in CISA KEV, but the combination of trivial exploitability and no forthcoming patch makes this a permanent risk for any still-deployed units.

Technical ContextAI

The TEW-432BRP is a legacy 802.11g SOHO wireless router whose web administration interface is implemented through a series of /goform/* CGI handlers - a common pattern in Realtek/Broadcom-based consumer router firmware of that era. CWE-121 (Stack-based Buffer Overflow) here arises because the formSetEnableWizard handler copies the user-supplied start_wizard HTTP parameter into a fixed-size stack buffer without bounds checking, allowing the saved return address or adjacent stack data to be overwritten. Because embedded MIPS/ARM firmware of this generation typically lacks ASLR, stack canaries, and non-executable stacks, classic return-address hijacking and shellcode injection remain straightforward on this CPE (cpe:2.3:a:trendnet:tew-432brp).

RemediationAI

No vendor-released patch identified at time of analysis, and the vendor has explicitly stated none will be produced because the device has been EOL since 2009; the only durable remediation is to decommission and replace affected TEW-432BRP units with a currently supported router. Until replacement is possible, restrict access to the web administration interface to a trusted management VLAN or single admin host via firewall ACLs, ensure WAN-side administration is disabled (this device historically defaulted to LAN-only admin, but verify), and change the admin password to a strong unique value to make the PR:L precondition harder to satisfy. Disabling or blocking the /goform/formSetEnableWizard path at an upstream reverse proxy is not practical on this device class, so network-layer isolation is the realistic compensating control; the trade-off is loss of remote manageability and continued exposure of any other unpatched flaws in the same firmware.
