CVE-2020-5428Network attack vector

Authenticated SQL injection via unchecked execution sorting

Published Jan 27, 2021 · Updated Sep 16, 2024

SQL injection in Spring Cloud Task 2.2.4 and earlier allows remote authenticated users to alter TaskExplorer lookup queries. TaskExplorer incorporates an externally influenced execution-sorting value into generated SQL without constraining it to valid sort fields. The flaw is reachable only when a consuming application exposes the affected lookup operation to a highly privileged user, enabling database reads or changes within the query's permissions.
