Stack-based Buffer Overflow in TRENDnet TEW-432BRP formSetPassword

IdentifiersCVE-2026-10162CWE-121· Stack-based Buffer Overflow

CVE-2026-10162 is a remotely exploitable stack-based buffer overflow in TRENDnet TEW-432BRP firmware 3.10B20. The flaw is in the formSetPassword function exposed through the /goform/formSetPassword endpoint. According to the provided record, manipulation of the webpage argument can trigger the overflow. Because the vulnerable condition is stack-based and reachable over the network, a crafted request to the password-setting handler can corrupt stack memory and destabilize the process, with possible code-execution implications depending on exploitability in the target environment. The issue affects an end-of-life product that TRENDnet states has been unsupported since 2009 and cannot be replicated or fixed by the vendor.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can cause memory corruption in the affected management endpoint, leading to denial of service and potentially arbitrary code execution on the device. The supplied scoring and advisory context indicate high impact to confidentiality, integrity, and availability. Because the flaw is reachable remotely, compromise of the device could enable full control of the affected router, including unauthorized configuration changes, interception or exposure of sensitive data handled by the device, and disruption of network services.

Mitigation

If you can’t patch tonight, do this now.

Where immediate replacement is not possible, minimize exposure by restricting access to the device management interface, especially the /goform/formSetPassword endpoint, to trusted administrative hosts only; place the device behind network segmentation and ACLs; disable remote administration if supported; prevent Internet exposure; and monitor for suspicious requests targeting password-management functionality. Because the product is unsupported, these are only risk-reduction measures and not a complete fix.

Remediation

Patch, then assume compromise.

No vendor patch is available. TRENDnet stated the affected TEW-432BRP product has been end-of-life for many years and cannot be fixed. The appropriate remediation is to decommission and replace affected TEW-432BRP devices running firmware 3.10B20 with supported hardware. If asset replacement is required, remove the vulnerable device from production use as soon as possible.
