CVE-2025-34068

Estado: AplazadaCrítica (9.3)—

An unauthenticated remote command execution vulnerability exists in Samsung WLAN AP WEA453e firmware prior to version 5.2.4.T1 via improper input validation in the “Tech Support” diagnostic functionality. The command1 and command2 POST or GET parameters accept arbitrary shell commands that are executed with root privileges on the underlying operating system. An attacker can exploit this by crafting a request that injects shell commands to create output files in writable directories and then access their contents via the download endpoint. This flaw allows complete compromise of the device without authentication. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-04 UTC.

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.

RCE remota sin autenticación en parámetros POST/GET (AV:N/PR:N/UI:N) ejecutada con privilegios root; CWE-306 (missing authentication) y acceso local remoto con control total del dispositivo.

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.
