CVE-2026-10179: Stack-based Buffer Overflow in TRENDnet TEW-432BRP
CVE-2026-10179 is a high-severity stack-based buffer overflow vulnerability in the TRENDnet TEW-432BRP router firmware version 3. 10B20. The flaw exists in the formSetWlanEncrypt function, which processes a webpage argument, allowing remote attackers to trigger the overflow. The product has been end-of-life (EOL) since 2009, and the vendor has stated they will not provide a fix or replicate the issue. Although an exploit is published, no known exploits are reported in the wild. This vulnerability affects only unsupported devices.
AI Analysis
Technical Summary
This vulnerability involves a stack-based buffer overflow in the formSetWlanEncrypt function of the TRENDnet TEW-432BRP router firmware 3.10B20. Remote attackers can manipulate the webpage argument to cause the overflow, potentially leading to code execution or denial of service. The product is EOL for over 15 years, and the vendor does not provide patches or mitigations. The CVSS 4.0 score is 8.7 (high), reflecting network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to remote code execution or denial of service on affected devices. Since the device is no longer supported and unpatched, affected systems remain vulnerable indefinitely. This could compromise network security where these devices are deployed.
Mitigation Recommendations
No official fix or patch is available due to the product's end-of-life status. Users should discontinue use of the TRENDnet TEW-432BRP device or isolate it from untrusted networks to mitigate risk. Replacement with a supported and patched device is strongly recommended. Patch status is not confirmed; check vendor communications for any updates, though none are expected.
