vulnerabilities
Pyramid Solutions NetStaX EtherNet/IP Stack
A stack-based buffer overflow in Pyramid Solutions NetStaX EtherNet/IP Stack versions prior to 5.6.1 allows large Class 3 explicit-message requests to bypass receive buffer validation. Exploitation could cause memory corruption, device crashes, or remote attacks without triggering error notifications. The vulnerability (CVE-2026-78012, CVSS 9.3) affects eight variants of the EtherNet/IP adapter and scanner toolkits used across manufacturing, energy, water, and chemical sectors worldwide.
Why it matters: Organizations deploying NetStaX EtherNet/IP Stack in operational technology environments must upgrade to version 5.6.1 immediately, as this network-accessible vulnerability requires no authentication and can silently compromise critical infrastructure devices across multiple sectors.
