CVE-2026-10183: Stack-based Buffer Overflow in TRENDnet TEW-432BRP
CVE-2026-10183 is a high-severity stack-based buffer overflow vulnerability in the TRENDnet TEW-432BRP router firmware version 3.10B20. The flaw exists in the formWlanSetup function, where manipulation of the enrollee argument can lead to a buffer overflow. The vulnerability can be exploited remotely without user interaction. However, the product has been end-of-life since 2009, and the vendor has stated they cannot replicate or fix this issue. No official patch or remediation is available.
AI Analysis
Technical Summary
This vulnerability affects the TRENDnet TEW-432BRP router running firmware version 3.10B20. Specifically, the formWlanSetup function in the /goform/formWlanSetup file improperly handles the enrollee argument, resulting in a stack-based buffer overflow. The vulnerability is remotely exploitable and does not require user interaction. The vendor has declared the product end-of-life for over 15 years and is unable to provide a fix. No patch or official remediation exists, and the exploit code is publicly available.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the affected device with elevated privileges, potentially compromising the router's functionality and network security. Given the high CVSS score (8.7) and the nature of the buffer overflow, the impact is significant. However, since the product is no longer supported and likely out of widespread use, the practical impact is limited to environments still operating this legacy hardware.
Mitigation Recommendations
No official fix or patch is available due to the product's end-of-life status. Users are advised to replace the affected TRENDnet TEW-432BRP devices with supported hardware to mitigate this vulnerability. Since the vendor cannot provide remediation, discontinuing use of the vulnerable device is the only effective mitigation.
