CVE-2017-14990

Estado: ModificadaMedia (6.5)—

La versión 4.8.2 de WordPress almacena valores wp_signups.activation_key en texto claro (pero almacena los valores análogos wp_users.user_activation_key como hashes), lo que podría facilitar que los atacantes remotos secuestren cuentas de usuario sin activar aprovechando el acceso de lectura a las bases de datos (como, por ejemplo, el acceso obtenido mediante una vulnerabilidad de inyección SQL sin especificar).

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).
