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.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
