CVE-2021-21427Network attack vector

Restricted-data access via misordered SQL quoting

Published Apr 21, 2021 · Updated Aug 3, 2024

Blind SQL injection in OpenMage LTS 19.4.12 and earlier and 20.0.8 and earlier allows remote authenticated users to access restricted resources. The MySQL adapter’s _prepareQuotedSqlCondition() quotes the condition template before replacing {{fieldName}}, leaving the substituted field expression outside the quoting operation. An administrator session with admin-console access is required, and the blind query oracle exposes data available to the application database account.
