The application's registerNewUser method executes an SQL query with executeQuery, at line 69 of /src/main/java/org/owasp/webgoat/lessons/sqlinjection/advanced/SqlInjectionChallenge.java. The application constructs this SQL query by embedding an untrusted string into the query without proper sanitization. The concatenated string is submitted to the database, where it is parsed and executed accordingly.

An attacker would be able to inject arbitrary syntax and data into the SQL query, by crafting a malicious payload and providing it via the input username_reg; this input is then read by the registerNewUser method at line 57 of /src/main/java/org/owasp/webgoat/lessons/sqlinjection/advanced/SqlInjectionChallenge.java. This input then flows through the code, into a query and to the database server - without sanitization.

This may enable an SQL Injection attack.
