Official Description

J2eeFAST 2.2.1 allows remote attackers to perform SQL injection via the (1) compId parameter to fast/sys/user/list, (2) deptId parameter to fast/sys/role/list, or (3) roleId parameter to fast/sys/role/authUser/list, related to the use of ${} to join SQL statements.

Source: NIST NVD / MITRE CVE Database

Attack Vector Analysis — CITED Relevance

The vulnerability arises from the improper handling of user input in the compId, deptId, and roleId parameters in the fast/sys/user/list, fast/sys/role/list, and fast/sys/role/authUser/list endpoints, respectively. The use of ${} to join SQL statements without proper sanitization leads to SQL injection.
