This vulnerability can be exploited using the manager URL parameter. Tricking a victim into visiting a specially crafted URL allows attackers to run arbitrary client-side scripting code within the victim's browser. The attacker-supplied code can perform a wide variety of actions, such as stealing the victim's session token or login credentials, performing arbitrary actions on the victim's behalf, and logging their keystrokes.

The following proof of concept demonstrates that it is possible to inject arbitrary JavaScript into the application's response in order to hijack the victim's session cookies:
