The application's Reg_update_Click method executes an SQL query with ExecuteNonQuery, at line 365 of /Registration.cs. 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 Value; this input is then read by the Reg_update_Click method at line 327 of /Registration.cs. This input then flows through the code, into a query and to the database server - without sanitization.

This may enable an SQL Injection attack.
