Researchers have unearthed 13 vulnerabilities affecting the Nucleus NET TCP/IP stack and have demonstrated how attackers could exploit them to cause serious real-world damage. The good news is that Siemens – the current owner of the stack –… Continue reading Vulnerabilities in Nucleus NET TCP/IP stack could lead to real-world damage
Researchers have discovered 14 new vulnerabilities affecting the proprietary NicheStack (aka InterNiche) TCP/IP stack, used in OT devices such as the extremely popular Siemens S7 PLCs. “Other major OT device vendors, such as Emerson, Honeywell, M… Continue reading Vulnerable TCP/IP stack is used by almost 200 device vendors
Forescout researchers have discovered nine vulnerabilities affecting nine different TCP/IP stacks widely used in IoT and OT devices. The vulnerabilities are due to weak Initial Sequence Number (ISN) generation, and could be exploited to mount limited D… Continue reading Vulnerabilities in widely used TCP/IP stacks open IoT, OT devices to attack
