CVE-2026-10181: Stack-based Buffer Overflow in TRENDnet TEW-432BRP
A vulnerability was found in TRENDnet TEW-432BRP 3.10B20. The affected element is the function formSysCmd of the file /goform/formSysCmd. Performing a manipulation of the argument submit-url results in stack-based buffer overflow. The attack can be initiated remotely. The exploit has been made public and could be used. The vendor explains: "This product has been EOL for 15 years (since 2009). As the item has been EOL for such a long time, we are not able to replicate or fix any vulnerabilities." This vulnerability only affects products that are no longer supported by the maintainer.
AI Analysis
Technical Summary
This vulnerability involves a stack-based buffer overflow in the formSysCmd function of the TRENDnet TEW-432BRP router firmware 3.10B20. By manipulating the submit-url argument remotely, an attacker can overflow the stack, potentially leading to code execution or denial of service. The product has been EOL for 15 years, and the vendor does not plan to issue a patch or mitigation. The CVSS 4.0 score is 8.7, reflecting high impact and exploitability with no user interaction required and low attack complexity.
Potential Impact
Successful exploitation can lead to remote code execution or denial of service on the affected device. Given the device is no longer supported and unpatched, affected systems remain vulnerable indefinitely. However, the lack of known active exploitation reduces immediate risk. The vulnerability compromises confidentiality, integrity, and availability with high impact.
Mitigation Recommendations
No official fix or patch is available due to the product's end-of-life status. Users should consider replacing the affected TRENDnet TEW-432BRP devices with supported hardware to mitigate risk. Network-level protections such as firewall rules restricting access to the device's management interface can reduce exposure. Patch status is not confirmed because the vendor explicitly states no fix will be provided.
