CVE-2016-15043

Estado: AnalizadaCrítica (9.8)—

The WP Mobile Detector plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in resize.php file in versions up to, and including, 3.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.

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/PR:N/UI:N indica explotación remota sin autenticación (T1190). Carga de archivos arbitrarios sin validación en resize.php permite web shell (T1505.003) y potencial ejecución de 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.
