Siemens Desigo DXR and PXC Controllers
Siemens has patched a denial-of-service vulnerability (CVE-2026-59693) affecting Desigo DXR and PXC controllers across multiple versions. An attacker sending malformed BACnet packets can cause the devices to stop responding, requiring a reset or reboot to restore function. Siemens recommends updating to the latest versions and securing network access to these building automation controllers.
Why it matters: Organizations operating Desigo DXR2, PXC3, PXC4, PXC5, or PXC7 controllers in commercial facilities, manufacturing, energy, healthcare, and transportation environments should prioritize updates to prevent attackers from disrupting critical building automation and process control systems.
