In Apache Fineract 0.4.0-incubating, 0.5.0-incubating, and 0.6.0-incubating, an authenticated user with client/loan/center/staff/group read permissions is able to inject malicious SQL into SELECT queries. The 'sqlSearch' parameter on a number of endpoints is not sanitized and appended directly to the query.
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.
