CX Parameter_Tampering @ WebGoatCoins/Autocomplete.ashx.cs [master] #146

Open jbruinaud opened 4 years ago

jbruinaud commented 4 years ago

Parameter_Tampering issue exists @ WebGoatCoins/Autocomplete.ashx.cs in branch master

Method ProcessRequest at line 20 of WebGoatCoins\Autocomplete.ashx.cs gets user input from element Request. This input is later concatenated by the application directly into a string variable containing SQL commands, without being validated. This string is then used in method GetCustomerEmails to query the database da, at line 558 of App_Code\DB\MySqlDbProvider.cs, without any additional filtering by the database. This could allow the user to tamper with the filter parameter.  

Severity: Medium

CWE:472

Checkmarx

Lines: 25

Code (Line #25):

            string query = context.Request["query"];
