CVE-2026-10577Network attack vector

Unauthenticated device control via exposed debug CLI

Published Jul 14, 2026 · Updated Jul 14, 2026

Missing authentication in Rockwell Automation 1715-AENTR firmware 3.003 and earlier allows remote attackers to access its debug CLI. The network-accessible debug port grants unauthenticated callers intrusive CLI commands that read or delete files, stop tasks, modify memory, and change I/O states. The only gate is network reachability to the port; no credentials or user interaction are required to alter device operation or interrupt control tasks.
