Untrusted initialization while creating SQL Connection

Hi Guys,

I have done the following...

private static IDbConnectionProvider CreateSqlConnectionProvider(DbConfig dbConfig)
{
	return
	new QcDbConnectionProvider(() =>
		{
			SqlConnectionStringBuilder csBuilder = new SqlConnectionStringBuilder();

			if (!string.IsNullOrEmpty(dbConfig.DataSource)) 
				csBuilder.DataSource = dbConfig.DataSource;
		   
			if (!string.IsNullOrEmpty(dbConfig.Database))
				csBuilder.InitialCatalog = dbConfig.Database;
		   
			csBuilder.IntegratedSecurity = dbConfig.IntegratedSecurity > 0;

			if (!string.IsNullOrEmpty(dbConfig.UserId)) 
				csBuilder.UserID = dbConfig.UserId;

			if (dbConfig.EncryptedPassword != null) 
				csBuilder.Password = Encryption.LocalEncryption.DecryptString(dbConfig.EncryptedPassword);
			
			csBuilder.Pooling = false;

			return new SqlConnection(csBuilder.ConnectionString);
		});
}

The client is using VERACODE tool for doing code analysis and the VERACODE has detected a flaw "Untrusted initialization" at

return new SqlConnection(csBuilder.ConnectionString);

Also, the dbConfig is being initialized as shown below...

DbConfig configDbConfig = new DbConfig
{
	Database = codeFile.ConfigurationDb,
	DataSource = codeFile.DataSource,
	IntegratedSecurity = sqlCredentials.UseWindowsAuthentication ? 1 : 0,
	UserId = sqlCredentials.UseWindowsAuthentication ? null : sqlCredentials.SqlUserName,
	ClearTextPassword = sqlCredentials.UseWindowsAuthentication ? null : sqlCredentials.SqlUserPassword
};

What I need to do in order to fix this flaw?
Thanks in advance.
