CVE-2022-45150

Estado: ModificadaMedia (6.1)—

Se descubrió una vulnerabilidad de Cross-Site Scripting (XSS) Reflejada en Moodle. Esta falla existe debido a una sanitización insuficiente de los datos proporcionados por los usuarios en la herramienta de políticas. Un atacante puede engañar a la víctima para que abra un enlace especialmente manipulado que ejecute un código HTML y script arbitrario en el navegador del usuario en el contexto de un sitio web vulnerable. Esta vulnerabilidad puede permitir a un atacante realizar ataques de Cross-Site Scripting (XSS) para obtener acceso a información potencialmente confidencial y modificación de páginas web.

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).
