CVE-2007-1420

Estado: ModificadaBaja (2.1)—💥 Exploit

MySQL versión 5.x anterior a 5.0.36, permite a los usuarios locales causar una denegación de servicio (bloqueo de base de datos) al realizar subselecciones de la tabla information_schema y utilizar ORDER BY para ordenar un resultado de una sola fila, lo que impide que determinados elementos de la estructura se inicialicen y desencadene una desreferencia de NULL en la función filesort.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
