What is CVE-2021-43974?
CVE-2021-43974 is a medium-severity missing authorization vulnerability in n/a, published on 11 Jan 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
An issue was discovered in SysAid ITIL 20.4.74 b10. The /enduserreg endpoint is used to register end users anonymously, but does not respect the server-side setting that determines if anonymous users are allowed to register new accounts. Configuring the server-side setting to disable anonymous user registration only hides the client-side registration form. An attacker can still post registration data to create new accounts without prior authentication.
Weakness: CWE-306
