CVE-2018-15811

Estado: AnalizadaAlta (7.5)⚠ Explotación activa

DNN (aka DotNetNuke) 9.2 through 9.2.1 uses a weak encryption algorithm to protect input parameters.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

AV:N/AC:L/PR:N indica vulnerabilidad remota sin privilegios en aplicación web expuesta (T1190). Cifrado débil (CWE-326) permite lectura de parámetros de entrada (T1005), confirmado por CVSS C:H.

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.
