CVE-2026-101354

Estado: AplazadaAlta (8.6)—

A security flaw has been discovered in FAST FAC1203R 20200116_2.0.4. The affected element is the function _tWlanTask of the component MmtAtePrase Parser. Performing a manipulation results in stack-based buffer overflow. The attacker must have access to the local network to execute the attack. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Stack-based buffer overflow en servicio de red local (WLAN) permite ejecución de código remoto. CWE-119/121 + AV:A sin PR confirma T1210. Impacto primario: ejecución de comandos via corrupción de memoria.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
