CERTFR-2024-AVI-0388

Vulnerability from certfr_avis - Published: 2024-05-13 - Updated: 2024-05-13

De multiples vulnérabilités ont été découvertes dans Moodle. Elles permettent à un attaquant de provoquer une injection de code indirecte à distance (XSS), une injection de requêtes illégitimes par rebond (CSRF), un contournement de la politique de sécurité.

Solution

Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

Moodle versions 4.1.x antérieures à 4.1.10
Moodle versions 4.2.x antérieures à 4.2.7
Moodle versions 4.3.x antérieures à 4.3.4

L'éditeur précise que les versions antérieures à 4.1.x sont vulnérables et ne bénéficieront pas de mises à jour de sécurité.
