The QNX RTOS monitor utility is prone to an issue which may allow local attackers to modify arbitrary system files (such as /etc/passwd). monitor is installed setuid root by default.

The monitor -f command line option may be used by a local attacker to cause an arbitrary system file to be overwritten. Once overwritten, the attacker will gain ownership of the file.
