ASP.NET ViewStateUserKey Is Not Set
Invicti detected that ASP.NET
ViewStateUserKey is not set inside of the ASP.NET application
When the ASP.NET
ViewStateUserKey is not set, that makes it easier for an attacker to perform CSRF attacks.
ViewStateUserKey prevents the attack by allowing you to assign an identifier to the view-state variable for individual users so that attackers cannot use the variable to generate an attack.
