CVE-2026-10122: Stack-based Buffer Overflow in TRENDnet TEW-432BRP
A vulnerability has been found in TRENDnet TEW-432BRP 3.10B20. This affects the function formSetProtocolFilter of the file /goform/formSetProtocolFilter. Such manipulation of the argument protocol_name leads to stack-based buffer overflow. The attack may be performed from remote. The exploit has been disclosed to the public and may 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
The vulnerability CVE-2026-10122 affects TRENDnet TEW-432BRP version 3.10B20. It is a stack-based buffer overflow triggered by improper handling of the protocol_name argument in the /goform/formSetProtocolFilter endpoint. The flaw allows remote attackers to potentially execute arbitrary code or cause a denial of service. The product has been EOL for over 15 years, and no official patch or remediation is available from the vendor. The CVSS 4.0 score is 8.7, indicating high severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to cause a stack-based buffer overflow, potentially leading to arbitrary code execution or denial of service on the affected device. Given the device is a router, compromise could impact network availability or security. However, the product is no longer supported, so no official fixes or mitigations are provided by the vendor.
Mitigation Recommendations
No official patch or fix is available due to the product being end-of-life since 2009. Users are advised to replace the affected TRENDnet TEW-432BRP device with a supported model to mitigate this vulnerability. Continued use of the vulnerable device carries risk as the vulnerability is publicly disclosed and potentially exploitable remotely.
