Vulnerability Title
Stack-based Buffer Overflow in Pyramid Solutions NetStaX EtherNet/IP Stack
来源: CVE Program / CVE List V5
Vulnerability Description
An issue in the NetStaX EtherNet/IP Stack prior to v5.6.1 could allow a large Class 3 explicit-message request to exceed the application-side receive buffer without generating an error or warning. The result could be memory corruption, a device crash, or a potential remote attack vector without the originating device receiving a CIP error indicating that the request could not be processed.
