Unauthenticated management access via missing identity checks

Published Jul 19, 2021 · Updated Sep 16, 2024

Improper authorization in Learning Digital Orca HCM 10.0 and earlier allows remote attackers to use management functions without logging in. The management page invokes member-data and course-administration functions without verifying the requester's identity. No account or user interaction is required; attackers can view member information and modify or delete courses, interrupting access to learning content.
