CVE-2022-45149

Estado: ModificadaMedia (5.4)—

Se encontró una vulnerabilidad en Moodle que existe debido a una validación insuficiente del origen de la solicitud HTTP en la URL de redireccionamiento del curso. El token CSRF de un usuario se incluyó innecesariamente en la URL cuando se le redirigió a un curso que acababa de restaurar. Un atacante remoto puede engañar a la víctima para que visite una página web especialmente manipulada y realizar acciones arbitrarias en nombre de la víctima en el sitio web vulnerable. Esta falla permite a un atacante realizar ataques de Cross-Site Request Forgery (CSRF).

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).
