Changing MOTP (Mobile One Time Password) system’s specific function parameter has insufficient validation for user input. A attacker in local area network can perform SQL injection attack to read, modify or delete backend database without authentication.
Solution:
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.
