Estado: AplazadaBaja (2.1)—

A vulnerability was detected in mathurvishal CloudClassroom-PHP-Project up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be. The impacted element is an unknown function. The manipulation results in cross-site request forgery. The attack can be launched remotely. The exploit is now public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The vendor was contacted early about this disclosure but did not respond in any way.

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.

CSRF en aplicación web con UI:P permite ejecutar acciones en contexto del usuario autenticado. Vector AV:N + requiere interacción del usuario sustenta T1203. Impactos: falsificación de solicitud (T1185) y potencial acceso a cuenta (T1078).

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.
