CVE-2007-2583

Estado: ModificadaMedia (4)—💥 Exploit
La función in_decimal::set en el archivo item_cmpfunc.cc en mySQL versiones anteriores a 5.0.40, y versiones 5.1 anteriores a 5.1.18-beta, permite a atacantes dependiendo del contexto causar una denegación de servicio (bloqueo) por medio de una cláusula IF especialmente diseñada que resulta en un error de división por cero y una desreferencia del puntero NULL.
CVSS

Versión: 2.0
Vector: AV:N/AC:L/Au:S/C:N/I:N/A:P
Puntuación base: 4
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 11%
Percentil entre todas las CVEs puntuadas: 96
Fecha de la puntuación: 10/10/2026
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.
