The device allows an unauthenticated attacker to bypass authentication and modify the cookie to reveal hidden pages that allows more critical operations to the transmitter.

A vulnerability, which was classified as critical, was found in MONyog Ultimate 6.63. This affects an unknown part of the component Cookie Handler. The manipulation of the argument HasServerEdit/IsAdmin leads to privilege escalation. It is possible to initiate the attack remotely.

The FlowMaster BPM Plus system from NewType has a privilege escalation vulnerability. Remote attackers with regular privileges can elevate their privileges to administrator by tampering with a specific cookie.

On Cellinx Camera with guest enabled, attacker with web access can elevate privileges to administrative: "1" to "0" privileges by changing the following cookie values from "is_admin", "showConfig". Administrative Privileges which allows changing various configuration in the camera.

rails_multisite provides multi-db support for Rails applications. In affected versions this vulnerability impacts any Rails applications using `rails_multisite` alongside Rails' signed/encrypted cookies. Depending on how the application makes use of these cookies, it may be possible for an attacker to re-use cookies on different 'sites' within a multi-site Rails application. The issue has been patched in v4 of the `rails_multisite` gem. Note that this upgrade will invalidate all previous signed/encrypted cookies. The impact of this invalidation will vary based on the application architecture.
