CVE-2017-20251

Estado: AplazadaCrítica (9.3)—

WordPress Insert PHP plugin versions before 3.3.1 contain a PHP code injection vulnerability that allows unauthenticated attackers to execute arbitrary PHP code by injecting malicious shortcodes through the WordPress REST API. Attackers can send POST requests to the wp-json/wp/v2/posts endpoint with crafted content containing insert_php shortcodes to include and execute remote PHP files 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.

Plugin WordPress expuesto en REST API sin autenticación (AV:N/PR:N/UI:N) permite inyección de código PHP arbitrario mediante shortcodes maliciosos (CWE-94), resultando en ejecución remota de comandos.

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.
