CVE-2021-47933

Estado: AplazadaCrítica (9.3)—

WordPress MStore API 2.0.6 contains an arbitrary file upload vulnerability that allows unauthenticated attackers to upload malicious files by sending POST requests to the REST API endpoint. Attackers can upload PHP files with arbitrary names to the config_file endpoint to achieve remote code execution on the server.

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.

API REST expuesta sin autenticación (PR:N, UI:N) permite subir archivos PHP arbitrarios para RCE. AV:N/AC:L → T1190. Impactos: ejecución de código (upload PHP) y acceso con credenciales del servidor web.

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.
