Synopsis

An application installed on the remote Windows host is affected by a remote code execution vulnerability.

Description

The version of Rockwell Studio 5000 Logix Designer installed on the remote Windows host is affected by a remote code execution vulnerability.

An attacker could alter the configuration to point to a malicious executable, resulting in arbitrary code execution when any user interacts with the external tools functionality. (CVE-2026-9127)
