Description Preview

An RCI service API in Copeland LP's E3 Supervisory Control firmware versions prior to 2.31F01 returns usernames and password hashes for application services (CWE-522). An attacker with network access and low privileges can retrieve these credential hashes (CAPEC-122: Privilege Abuse), which may be cracked offline or reused to gain higher privileges, compromise integrity and availability of systems, and move laterally. CVSSv4.0 base score 7.7 (AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/S:U).

Overview

The vulnerability arises from insufficient protection of stored credentials exposed by an RCI API call in E3 Supervisory Control firmware (< 2.31F01). A remote actor with network access to the device interface (ETH0) and low privileges can retrieve all usernames and password hashes for application services. Exploitation can lead to account compromise, privilege escalation to administrative functions, unauthorized configuration changes, and service disruption. Discovered and credited to Armis Labs; publicly documented 2025-07-29.

Remediation

Upgrade affected E3 Supervisory Controls to a patched firmware version (apply vendor update; vendor guidance indicates upgrading to a version greater than 2.30F1 / 2.31F01 or later). As an immediate mitigation, restrict access to the device management network interface (ETH0) using a dedicated VLAN or subnet and network firewall rules so it is never reachable from untrusted networks. Where exposure is suspected, rotate all application service credentials and hashes, enforce strong passwords, disable or tightly restrict RCI access if possible, monitor for unusual authentication and configuration activity, and apply the firmware update as soon as it is available via vendor channels.
