CVE-2026-10577 is rated critical with a CVSS v4.0 base score of 10.0. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.
Vulnerability description
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.
