Synopsis

An application running on the remote host is affected by a denial of service vulnerability.

Description

The remote host has a version of RSLinx Classic installed that is prior or equal to 2.57.00.14. It is, therefore, potentially affected by a denial of service vulnerability in the Ethernet/IP server implementation. A remote, unauthenticated attacker could cause the device to crash by sending a specially crafted sequence of packets.
