CVE-2021-29396Network attack vector

Privileged-function access via missing authentication

Published Feb 4, 2022 · Updated Aug 3, 2024

Authentication bypass in Northstar Technologies Inc NorthStar Club Management 6.3 allows remote attackers to access privileged functions. The web application serves multiple file-management, user-file, download, and command-output resources without first enforcing authentication. No credentials are required; reachable resources expose stored files or privileged actions, while the exact consequence depends on the requested resource.
