CVE-2026-10121

Status: DeferredHigh (7.4)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Buffer overflow remoto en parámetro web (formSetUrlFilter) requiere PR:L (privilegios), indicando acceso a servicio remoto adyacente. Stack overflow permite ejecución de código arbitrario (T1059).
