CWE-842: Placement of User into Incorrect Group
The product or the administrator places a user into an incorrect group.
How it's found
Placement of User into Incorrect Group is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
If the incorrect group has more access or privileges than the intended group, the user might be able to bypass intended security policy to access unexpected resources or perform unexpected actions. The access-control system might not be able to detect malicious usage of this group membership.
Consequences
