SIPLUS variants) (All versions), SIMATIC IPC DiagBase (All versions), SIMATIC IPC DiagMonitor (All versions), SIMATIC WinCC Runtime Advanced (All versions), SIPLUS TIM 1531 IRC (6AG1543-1MX00-7XE0) (All versions \u003c V2.4.8), TIM 1531 IRC (6GK7543-1MX00-0XE0) (All versions \u003c V2.4.8). The web server of the affected devices do not properly handle the shutdown or reboot request, which could lead to the clean up of certain resources. \r\n\r\nThis could allow a remote attacker with elevated privileges to cause a denial of service condition in the system. SIMATIC CP 1242 and CP 1243 related processors connect SIMATIC S7-1200 controllers to wide area networks (WANs). They offer integrated security features such as firewalls, virtual private networks (VPNs) and support for other data encryption protocols. SIMATIC HMI Panels are used for operator control and monitoring of machines and plants. SIMATIC IPC DiagBase diagnostics software allows early identification of any potential faults on SIMATIC industrial computers and helps to avoid or reduce system downtime. SIMATIC IPC DiagMonitor monitors, reports, visualizes and logs the system status of SIMATIC IPCs. It communicates with other systems and reacts when events occur. Communication processor (CP) modules SIMATIC TIM 3V-IE and TIM 4R-IE are designed to enable Ethernet or telecontrol communication for SIMATIC S7-300/S7-400 CPUs. SIMATIC WinCC Runtime Advanced is a visualization runtime platform for operator control and monitoring of machines and plants. SIPLUS extreme products are designed for reliable operation under extreme conditions and are based on SIMATIC, LOGO!, SITOP, SINAMICS, SIMOTION, SCALANCE or other devices. SIPLUS devices use the same firmware as the products they are based on. \n\nSiemens Industrial products have a null pointer dereference vulnerability",
