ABB Cylon Aspect 3.08.01 jsonProxy.php Username Enumeration

ABB Cylon Aspect version 3.08.01 is vulnerable to username enumeration in the jsonProxy.php endpoint. An unauthenticated attacker can interact with the UserManager servlet to enumerate valid usernames on the system. Since jsonProxy.php proxies requests to internal services without requiring authentication, attackers can gain unauthorized insights into valid usernames.
