Description
An issue was discovered in Amcrest Web Server 2.520.AC00.18.R 2017-06-29 WEB 3.2.1.453504. The login page responds with JavaScript when one tries to authenticate. An attacker who changes the result parameter (to true) in this JavaScript code can bypass authentication and achieve limited privileges (ability to see every option but not modify them).
