Allocation of resources without limits or throttling in .NET allows an unauthorized attacker to deny service over a network.

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.

CVSS AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). CWE-770 y descripción explícita de DoS por asignación ilimitada de recursos confirma T1499.004 (application exhaustion).

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.
