CVE-2026-10162: Stack-based Buffer Overflow in TRENDnet TEW-432BRP
CVE-2026-10162 is a high-severity stack-based buffer overflow vulnerability in the TRENDnet TEW-432BRP router firmware version 3. 10B20. The flaw exists in the formSetPassword function accessed via /goform/formSetPassword, where manipulation of the 'webpage' argument can trigger the overflow. The vulnerability can be exploited remotely without user interaction and requires low privileges. Although an exploit has been published, the product has been end-of-life (EOL) since 2009, and the vendor does not provide patches or fixes due to the age of the device. This vulnerability affects only unsupported devices.
AI Analysis
Technical Summary
The TRENDnet TEW-432BRP router firmware 3.10B20 contains a stack-based buffer overflow vulnerability in the formSetPassword function, reachable through the /goform/formSetPassword endpoint. An attacker with low privileges can remotely manipulate the 'webpage' argument to cause a buffer overflow, potentially leading to code execution or denial of service. The vulnerability is rated high severity with a CVSS 4.0 score of 8.7. The device has been EOL since 2009, and the vendor has explicitly stated they will not replicate or fix this issue. No official patch or remediation is available.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker with low privileges to execute arbitrary code or cause a denial of service on the affected device. Given the device is no longer supported and unpatched, affected systems remain vulnerable. However, the impact is limited to devices running the specific outdated firmware version 3.10B20 of the TEW-432BRP model.
Mitigation Recommendations
No official fix or patch is available due to the product being EOL since 2009. The vendor has stated they cannot replicate or fix the vulnerability. Mitigation options include discontinuing use of the affected device and replacing it with a supported model. Network-level protections such as restricting remote access to the device management interface can reduce exposure. Patch status is not confirmed as no vendor fix exists.
