CVE-2020-36950

Estado: AplazadaAlta (8.7)—

Laravel Nova 3.7.0 contains a denial of service vulnerability that allows authenticated users to crash the application by manipulating the 'range' parameter. Attackers can send simultaneous requests with an extremely high range value to overwhelm and crash the server.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:N permite explotación remota sin privilegios (T1190); CWE-770 (asignación excesiva de recursos) y descripción de crash por parámetro 'range' indican DoS de aplicación (T1499.004).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
