DUportal Pro is prone to multiple SQL injection vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input before using it in SQL queries.

Successful exploitation could result in a compromise of the application, disclosure or modification of data, or may permit an attacker to exploit vulnerabilities in the underlying database implementation.

Some of these issues may have previously been discussed in BID 13285 and BID 13288.
