Multiple denial-of-service vulnerabilities exist in the UMAS protocol functionality of the Schneider Electric Modicon M580 Programmable Automation Controller, firmware version SV2.70. Specially crafted UMAS commands can cause the device to enter a non-recoverable fault state, resulting in a complete stoppage of remote communications with the device. An attacker can send unauthenticated commands to trigger these vulnerabilities.
