CVE-2021-22850Network attack vector

Unauthenticated data access via unprotected privileged pages

Published Jan 19, 2021 · Updated Sep 17, 2024

Missing access control in HGiga OAKlouds Document 2.0 and 3.0 allows remote attackers to read sensitive data via privileged pages. Certain portal pages expose database content and privileged functions without enforcing authentication, but neither public advisory identifies the pages or faulty authorization check. Network access alone is sufficient, while the CNA assessment confirms only limited confidentiality impact and no demonstrated data alteration or interruption.
