CVE-2021-37422Network attack vector

Data exposure via unsanitized account-linking usernames

Published Sep 10, 2021 · Updated Aug 4, 2024

SQL injection in ManageEngine ADSelfService Plus 6101 and earlier allows remote attackers to read application data through crafted usernames. During Active Directory-to-Oracle Database account linking, the application inserts supplied usernames into SQL queries without sanitization and sends them to Oracle. Successful Boolean-based injection reads ADSelfService Plus data, and reachability requires Oracle Database password synchronization to be enabled.
