CVE-2026-10181: Stack-based Buffer Overflow in TRENDnet TEW-432BRP
CVE-2026-10181 is a stack-based buffer overflow vulnerability in the TRENDnet TEW-432BRP router firmware version 3. 10B20. The flaw exists in the formSysCmd function handling the submit-url argument, allowing remote attackers to trigger the overflow. The product has been end-of-life (EOL) since 2009, and the vendor does not provide patches or fixes. Although the exploit code is publicly available, the vulnerability affects only unsupported devices.
AI Analysis
Technical Summary
This vulnerability involves a stack-based buffer overflow in the formSysCmd function of the /goform/formSysCmd endpoint in TRENDnet TEW-432BRP firmware 3.10B20. Remote attackers can manipulate the submit-url parameter to cause the overflow. The product has been EOL for over 15 years, and the vendor has stated they cannot replicate or fix the issue. No official patch or remediation is available. The CVSS 4.0 score is 8.7, indicating high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to a stack-based buffer overflow, potentially allowing remote code execution or denial of service on affected devices. Since the device is no longer supported and unpatched, affected systems remain vulnerable if still in use. The high CVSS score reflects significant potential impact on device security.
Mitigation Recommendations
No official fix or patch is available due to the product's end-of-life status. The vendor explicitly states they cannot replicate or remediate the vulnerability. Mitigation requires discontinuing use of the affected TRENDnet TEW-432BRP devices or isolating them from untrusted networks to prevent remote exploitation.
