publishedCWE-20CWE-269

IXP Manager is a full-stack web application for managing Internet Exchange Points. Prior to version 7.3.0, an authenticated, non-administrative user can elevate their privileges to administrator status. Restricting administrative functions reduces exposure but is not a complete fix. This issue is fixed in version 7.3.0.
