CVE-2022-31625

Estado: ModificadaAlta (8.1)—

En PHP versiones 7.4.x anteriores a 7.4.30, 8.0.x anteriores a 8.0.20 y 8.1.x anteriores a 8.1.7, cuando es usada la extensión de la base de datos Postgres, el suministro de parámetros no válidos a la consulta parametrizada puede conllevar que PHP intente liberar memoria usando datos no inicializados como punteros. Esto podría conllevar a una vulnerabilidad RCE o una denegación de servicio

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).
