CVE-2021-47871

Estado: AplazadaAlta (8.6)—

Hestia Control Panel 1.3.2 contains an arbitrary file write vulnerability that allows authenticated attackers to write files to arbitrary locations using the API index.php endpoint. Attackers can exploit the v-make-tmp-file command to write SSH keys or other content to specific file paths 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.

Acceso remoto con privilegios (PR:H) a API expuesta permite escribir archivos arbitrarios (CWE-73); impacto: web shell, gestión de cuentas SSH, datos persistentes en el servidor.

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.
