CX SQL_Injection @ WebGoatCoins/CustomerLogin.aspx.cs [master]

[jbruinaud]

SQL_Injection issue exists @ WebGoatCoins/CustomerLogin.aspx.cs in branch master

The application's IsValidCustomerLogin method executes an SQL query with da, at line 112 of App_Code\DB\MySqlDbProvider.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. The attacker would be able to inject arbitrary data into the SQL query, by simply altering the user input Text, which is read by the ButtonLogOn_Click method at line 31 of WebGoatCoins\CustomerLogin.aspx.cs. This input then flows through the code to the database server, without sanitization. This may enable an SQL Injection attack.
