CX Reflected_XSS_All_Clients @ ProxySetup.aspx.cs [master] #210

Open jbruinaud opened 4 years ago

jbruinaud commented 4 years ago

Reflected_XSS_All_Clients issue exists @ ProxySetup.aspx.cs in branch master

Method btnReverse_Click at line 12 of ProxySetup.aspx.cs gets user input for the Text element. This element’s value then flows through the code without being properly sanitized or validated and is eventually displayed to the user in method btnReverse_Click at line 12 of ProxySetup.aspx.cs. This may enable a Cross-Site-Scripting attack.

Severity: High

CWE:79

Lines: 15

Code (Line #15):

            var name = txtName.Text;
