Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability affects TRENDnet TEW-432BRP 3.10B20 devices due to a buffer overflow in the formSetUrlFilter function. The issue can be exploited remotely by manipulating specific arguments. While an exploit has been published, the vendor has stated the product has been end-of-life for 15 years and is unsupported, meaning the vendor cannot provide a fix. This vulnerability therefore only impacts organizations still using this unsupported hardware.
- Identify exposed TRENDnet TEW-432BRP 3.10B20 devices.
- Isolate or decommission affected devices.
- Monitor for related security incidents.
