Reason and prerequisites
Archivelink executes certain functions through referencing specific URLs. When an attacker tricks an authenticated user’s browser into making a request containing a certain URL and specific parameters, the function is executed with the rights of the user. If present, the attacker may use a Cross Site Scripting attack to trigger the exploit, or use an approach in which a link to click is presented to the victim.
