CVE-2022-23342Public exploitNetwork attack vector

Account discovery via distinguishable login responses

Published Jun 21, 2022 · Updated Aug 3, 2024

Username enumeration in Hyland OnBase before 20.3.58.1000 and 21.1.1.1000 through 21.1.15.1000 allows remote attackers to identify valid users. The Connect endpoint returns distinguishable results for valid and invalid credentials when a crafted login POST is submitted. No authentication is required, and the disclosed information identifies Active Directory accounts without changing data or interrupting service.
