SQL Injection
Invicti identified a Probable SQL Injection, which occurs when data input by a user is interpreted as an SQL command rather than as normal data by the backend database.
This is an extremely common vulnerability and its successful exploitation can have critical implications.
Even though Invicti believes there is a SQL injection in here, it could not confirm it. There can be numerous reasons for Invicti not being able to confirm this. We strongly recommend investigating the issue manually to ensure it is an SQL injection and that it needs to be addressed. You can also consider sending the details of this issue to us so we can address this issue for the next time and give you a more precise result.
- Reading, updating and deleting arbitrary data/tables from the database.
- Executing commands on the underlying operating system.
- See the remedy for solution.
- If you are not using a database access layer (DAL) within the architecture consider its benefits and implement if appropriate. As a minimum the use of s DAL will help centralize the issue and its resolution. You can also use ORM (object relational mapping). Most ORM systems use parameterized queries and this can solve many if not all SQL injection based problems.
- Locate all of the dynamically generated SQL queries and convert them to parameterized queries. (If you decide to use a DAL/ORM, change all legacy code to use these new libraries.)
- Monitor and review weblogs and application logs to uncover active or previous exploitation attempts.
