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.
Remediation
Install update from vendor's website.
