Detailed vulnerability description

The vulnerability allows a local authenticated user to manipulate data.

lib/xymond_ipc.c in Xymon 4.1.x, 4.2.x, and 4.3.x before 4.3.25 use weak permissions (666) for an unspecified IPC message queue, which allows local users to inject arbitrary messages by writing to that queue.
