CVE-2021-26686Network attack vector

Authenticated SQL injection through management API

Published Feb 23, 2021 · Updated Aug 3, 2024

SQL injection in Aruba ClearPass Policy Manager before 6.9.5, 6.8.8-HF1, or 6.7.14-HF1 lets remote authenticated users read and modify database data. HPE identifies the locus only as the web-based management interface API and has not disclosed the affected endpoint or how API input reaches an SQL statement. A valid management-interface account is required, and successful exploitation is limited to reading and changing sensitive information in the underlying database.
