CVE-2026-10121: Stack-based Buffer Overflow in TRENDnet TEW-432BRP
A flaw has been found in TRENDnet TEW-432BRP 3.10B20. The impacted element is the function formSetUrlFilter of the file /goform/formSetUrlFilter. This manipulation of the argument keyword_list/keyword causes stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been published 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
This vulnerability involves a stack-based buffer overflow in the formSetUrlFilter function of the TRENDnet TEW-432BRP router firmware version 3.10B20. An attacker can remotely trigger the overflow by manipulating the keyword_list parameter in the /goform/formSetUrlFilter endpoint. The overflow could lead to potential code execution or denial of service. The product has been EOL for over 15 years, and the vendor has explicitly stated they will not address this vulnerability. No patch or official remediation exists.
Potential Impact
Successful exploitation of this vulnerability allows a remote attacker to cause a stack-based buffer overflow, potentially leading to arbitrary code execution or denial of service on the affected device. Since the device is no longer supported and unpatched, affected routers remain vulnerable if exposed to untrusted networks.
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 currently supported hardware. Network-level protections such as firewall rules restricting access to the device's management interface from untrusted networks may reduce exposure.
