controllers/member/Api.php in dayrui FineCms 5.2.0 has SQL Injection: a request with s=member,c=api,m=checktitle, and the parameter 'module' with a SQL statement, lacks effective filtering.
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.
