What is CVE-2020-10276?
CVE-2020-10276 is a critical vulnerability in Mobile Industrial Robots A/S MiR100, published on 24 Jun 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The password for the safety PLC is the default and thus easy to find (in manuals, etc.). This allows a manipulated program to be uploaded to the safety PLC, effectively disabling the emergency stop in case an object is too close to the robot. Navigation and any other components dependent on the laser scanner are not affected (thus it is hard to detect before something happens) though the laser scanner configuration can also be affected altering further the safety of the device.
