NVD description

A security issue exists within ControlFLASH™, where the installer grants write permissions to the "Everyone" group on a product installation directory. This could allow arbitrary code execution, resulting in an attacker being given the ability to run any commands or code of the attacker's choice on a target machine at the logged-in user's permission level.

    Active Exploitation

    TRC analysis shows attackers exploiting CVE-2026-12663 in Rockwell ControlFLASH can escalate privileges through excessive 'Everyone' permissions, then pivot laterally through connected industrial systems. Runtime segmentation helps contain post-compromise activity in OT environments. #CloudSecurity 🔗 Full breakdown: https://aviatrix.ai/threat-research-center/rockwell-automation-controlflash-cve-2026-12663-vulnerability

    Post summary

    CVE-2026-12663 is being actively exploited for privilege escalation via 'Everyone' permissions and lateral movement in Rockwell ControlFLASH, with runtime segmentation offered as a mitigative measure.
