Sysmac Studio provided by OMRON Corporation contains an incorrect authorization vulnerability. If this vulnerability is exploited, an attacker may access the program which is protected by Data Protection function.

Project files may contain malicious contents which the software will use to create files on the filesystem. This allows directory traversal and overwriting files with the privileges of the logged-in user.

Authentication bypass by capture-replay vulnerability exists in Machine automation controller NJ series all models V 1.48 and earlier, Machine automation controller NX7 series all models V1.28 and earlier, Machine automation controller NX1 series all models V1.48 and earlier, Automation software 'Sysmac Studio' all models V1.49 and earlier, and Programmable Terminal (PT) NA series NA5-15W/NA5-12W/NA5-9W/NA5-7W models Runtime V1.15 and earlier, which may allow a remote attacker who can analyze the communication between the affected controller and automation software 'Sysmac Studio' and/or a Programmable Terminal (PT) to access the controller.
