CVE-2026-10577 in EtherNet IP Communications Module
Summary
by MITRE • 07/14/2026
A security issue exists within the 1715-AENTR EtherNet/IP Adapter. The affected product exposes a network-accessible debug port that does not enforce proper privilege controls, allowing unauthenticated remote access to intrusive command-line interface (CLI) commands. If exploited, a threat actor could read or delete files, stop tasks, modify memory, and change I/O states, potentially impacting the confidentiality, integrity, and availability of the device.

The security vulnerability identified in the 1715-AENTR EtherNet/IP Adapter represents a critical exposure that undermines the fundamental security posture of industrial network infrastructure. This device, designed for industrial automation and control systems, contains an unintended debug port that remains accessible over the network without proper authentication mechanisms. The flaw stems from inadequate privilege controls within the device's firmware implementation, creating an attack surface that directly contradicts standard security practices for industrial equipment. The exposed debug interface operates as a command-line interface that provides direct system access, bypassing normal operational controls and validation checks that should be mandatory for any production industrial device.
The technical nature of this vulnerability aligns with CWE-284, which addresses improper access control mechanisms, and specifically manifests as an authentication bypass issue within network services. Threat actors exploiting this weakness can gain unauthorized command-line access to the device's operating system, enabling them to execute arbitrary commands that directly impact system functionality. The operational implications extend beyond simple unauthorized access, as the vulnerability allows for complete system manipulation through capabilities including file operations, process management, memory modification, and input/output state changes. This comprehensive access level represents a severe compromise that can disrupt industrial processes, potentially leading to production downtime, safety hazards, or data corruption.
The impact of exploitation demonstrates clear violations of the CIA triad fundamental to information security. Confidentiality is compromised through unauthorized file reading capabilities that could expose sensitive operational data, configuration files, or proprietary process information. Integrity suffers as threat actors can modify memory contents and change I/O states, potentially altering control signals sent to industrial equipment. Availability is threatened through the ability to stop system tasks, effectively creating denial-of-service conditions that could halt production processes. From an adversarial perspective, this vulnerability maps directly to ATT&CK technique T1059.007 for command and scripting interpreter, while also supporting lateral movement and persistence activities through the debug interface.
Organizations operating these devices must implement immediate mitigations including network segmentation to isolate affected equipment from general network access, disabling unused network ports, and applying firmware updates when available from the vendor. The vulnerability highlights the critical importance of secure-by-design principles in industrial control systems, where default configurations should never expose debugging interfaces to external networks. Regular security assessments of industrial network infrastructure should include verification of exposed services and ports, with particular attention to legacy or older equipment that may contain undocumented debug capabilities. Additionally, implementing network monitoring solutions capable of detecting unusual command-line access patterns can help identify potential exploitation attempts before they result in operational disruption.
