CVE-2026-10577 is a critical access control vulnerability in the Rockwell Automation 1715-AENTR EtherNet/IP Adapter, also described as the 1715 EtherNet/IP Communications Module. The issue arises because a network-accessible debug port does not enforce proper authentication or privilege controls, exposing intrusive command-line interface functionality to unauthenticated remote users. An attacker able to reach the debug interface can invoke privileged CLI commands to interact directly with the device runtime and storage. Reported capabilities include reading or deleting files, stopping tasks, modifying memory, and changing I/O states. The vulnerability affects firmware version 3.003 and earlier and is fixed in firmware 3.011.
