CVE-2017-5671

Honeywell Intermec PM23, PM42, PM43, PC23, PC43, PD43, and PC42 industrial printers before 10.11.013310 and 10.12.x before 10.12.013309 have /usr/bin/lua installed setuid to the itadmin account, which allows local users to conduct a BusyBox jailbreak attack and obtain root privileges by overwriting the /etc/shadow file.

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
