Cross-site request forgery (CSRF) vulnerability in SecuritySetting/UserSecurity/UserManagement.aspx in B.A.S C2Box before 4.0.0 (r19171) allows remote attackers to hijack the authentication of administrators for requests that add administrator accounts via certain vectors.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
