CVE-2023-2987

Estado: ModificadaCrítica (9.8)—

El plugin Wordapp para WordPress es vulnerable a una omisión de autorización debido al uso de una firma criptográfica insuficientemente única en la función "wa_pdx_op_config_set" en versiones hasta la 1.5.0 inclusive. Esto hace posible que atacantes no autenticados al plugin cambien el "validation_token" en la configuración del plugin, proporcionando acceso a las funcionalidades de control remoto del plugin, como la creación de una URL de acceso de administrador, que puede ser utilizada para la esclada de privilegios.

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).
