CVE-2025-6679

Estado: AplazadaCrítica (9.8)—

The Bit Form builder plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 2.20.4. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. For this to be exploitable, the PRO version needs to be installed and activated as well. Additionally a form with an advanced file upload element needs to be published.

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.

AV:N/AC:L/PR:N sin UI:R indica aplicación web expuesta (T1190). CWE-434 + carga de archivos arbitrarios + mención explícita de RCE justifican T1505.003 (web shell) e T1059 (ejecución de código remota resultante).

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.
