Microsoft discovered and responsibly disclosed two vulnerabilities in Rockwell Automation PanelView Plus that could be remotely exploited by unauthenticated attackers, allowing them to perform remote code execution (RCE) and denial-of-service (DoS).
The RCE vulnerability in PanelView Plus involves two custom classes that can be abused to upload and load a malicious DLL into the device. The DoS vulnerability takes advantage of the same custom class to send a crafted buffer that the device is unable to handle properly, thus leading to a DoS. PanelView Plus devices are graphic terminals, also known as human machine interface (HMI) and are used in the industrial space.
