Descriptions

In Keepalived through 2.2.4, the D-Bus policy does not sufficiently restrict the message destination, allowing any user to inspect and manipulate any property. This leads to access-control bypass in some situations in which an unrelated D-Bus system service has a settable (writable) property

En Keepalived versiones hasta 2.2.4, la política D-Bus no restringe suficientemente el destino de los mensajes, permitiendo a cualquier usuario inspeccionar y manipular cualquier propiedad. Esto conlleva a una omisión del control de acceso en algunas situaciones en las que un servicio del sistema D-Bus no relacionado presenta una propiedad configurable (escribible)

A flaw was found in keepalived, where an improper authentication vulnerability allows an unprivileged user to change properties that could lead to an access-control bypass.
