CX Blind_SQL_Injections @ WebGoatCoins/ChangePassword.aspx.cs [master]

[jbruinaud]

Blind_SQL_Injections issue exists @ WebGoatCoins/ChangePassword.aspx.cs in branch master

The application's UpdateCustomerPassword method executes an SQL query with command, at line 295 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. If an exception is thrown by the database code, it is caught and handled. An attacker could still use inferential or boolean exploitation techniques to retrieve the data, by altering the user input Text. This is read in the ButtonChangePassword_Click method, at line 21 of WebGoatCoins\ChangePassword.aspx.cs, and used without sanitization in the SQL query that is sent to the database server.  This may enable a Blind SQL Injection attack.
