In short
Programmable Logic Controllers (PLCs) from major manufacturers can be crashed by flooding them with network packets, causing them to stop working. This affects critical industrial systems and infrastructure that rely on these controllers to operate.
Technical detail
A remote, unauthenticated attacker can trigger a denial-of-service condition by sending a high volume of crafted network packets to vulnerable PLCs (ABB, Phoenix Contact, Schneider Electric, Siemens, WAGO). The attack exploits insufficient input validation or resource exhaustion mechanisms, resulting in service unavailability of industrial control systems.
Summary generated and translated by AI from the official description.
ABB, Phoenix Contact, Schneider Electric, Siemens, WAGO - Programmable Logic Controllers, multiple versions. Researchers have found some controllers are susceptible to a denial-of-service attack due to a flood of network packets.
