CVE-2024-43427Network attack vector

Secret disclosure via incomplete preset export filtering

Published Nov 11, 2024 · Updated Nov 12, 2024

Information disclosure in Moodle LMS allows attackers to obtain secrets and keys from shared site administration preset exports. The administration preset exporter serializes sensitive configuration values instead of excluding them from the export package. Exposure requires an administrator to create and share an export with an untrusted third party; integrity and availability are unaffected.
