Unauthorized Active Directory data modification
Published Oct 13, 2021 · Updated Aug 4, 2024
Security feature bypass in Active Directory on affected Windows Server releases allows remote authenticated users to alter directory data. Microsoft has not disclosed the affected code locus or the incorrect operation performed on attacker-controlled input. Exploitation requires high-privilege network access, and the disclosed consequence is unauthorized modification rather than data exposure or service interruption.
