CVE-2024-51138
Estado: ModificadaCrítica (9.8)—

This flaw occurs due to insufficient bounds checking on the amount of URL parameters, allowing an attacker to exploit the overflow by sending a maliciously crafted request. Consequently, a remote attacker can execute arbitrary code with elevated privileges.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 9.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.05%
- Percentil entre todas las CVEs puntuadas: 63
- Fecha de la puntuación: 5/10/2026
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).
