CVE-2025-4102
The Beaver Builder Plugin (Starter Version) plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'save_enabled_icons' function in all versions up to, and including, 2.9.1. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The vulnerability was partially patched in version 2.9.1.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1210Exploitation of Remote Serviceslateral movement75 % - Impacto principal
T1505.003Web Shellpersistence85 % - Impacto secundario
T1059Command and Scripting Interpreterexecution70 %
AV:N, PR:H y acceso remoto sin privilegios de red adyacente sugieren T1210. La falta de validación de tipo de archivo (CWE-434) permite cargar web shell (T1505.003) y ejecutar código (T1059) en el servidor WordPress.
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.
