Attack Chain

1. An unauthenticated attacker identifies a Rockwell Automation 1715-AENTR EtherNet/IP Adapter device running an affected firmware version (<=3.003) via network scanning.
2. The attacker establishes a network connection to the device's exposed debug port, which lacks proper authentication mechanisms.
3. Leveraging the missing authentication, the attacker gains unauthenticated remote access to the device's intrusive command-line interface (CLI).
4. The attacker executes CLI commands to read or delete files on the device's file system.
5. The attacker issues commands to stop tasks, potentially disrupting critical industrial processes.
6. The attacker exploits the CLI access to modify the device's memory, potentially altering operational parameters or firmware.
7. The attacker manipulates I/O states, gaining control over physical processes connected to the adapter.
8. The final objective is complete compromise of the device, leading to impacts on confidentiality, integrity, and availability of the connected industrial control system.

Impact

Successful exploitation of CVE-2026-10577 allows an unauthenticated attacker to gain full control over the Rockwell Automation 1715-AENTR EtherNet/IP Adapter, leading to severe operational disruptions. Attackers can read or delete device files, stop critical tasks, modify memory, and alter I/O states, directly affecting the operational integrity and safety of industrial processes. This vulnerability places critical infrastructure sectors, including Energy, Water and Wastewater, and Critical Manufacturing, at high risk. Compromise of these devices could result in unauthorized process changes, data corruption, denial of service, or even physical damage to machinery and infrastructure, with potential for widespread outages and safety hazards. Given the global deployment of these devices, the potential for broad impact across multiple regions is significant.

Recommendation

• Update Rockwell Automation 1715-AENTR EtherNet/IP Adapter devices to version 3.011 or later to remediate CVE-2026-10577.
• Minimize network exposure for all control system devices and systems, ensuring the Rockwell Automation 1715-AENTR EtherNet/IP Adapter is not accessible from the internet.
• Implement network segmentation by locating control system networks and remote devices behind firewalls and isolating them from business networks.
• When remote access to the Rockwell Automation 1715-AENTR EtherNet/IP Adapter is necessary, utilize secure methods such as Virtual Private Networks (VPNs) and ensure VPNs are updated to the most current version.
