Technical description

The public consent endpoint of JTL-Shop accepts arbitrary consent names from unauthenticated visitors without validating them against the configured consent items. These names are stored in the consent statistics and rendered without output encoding in the administration backend. An unauthenticated remote attacker can thereby inject script code that is executed in the browser session of an administrator viewing the consent statistics page, allowing actions to be performed with the administrator's privileges.
