Description Preview

An unauthenticated network-accessible API in Copeland LP E3 Supervisory Control (MGW) firmware versions less than 2.31F01 fails to validate input properly (CWE-20), enabling an attacker to send crafted requests that continuously crash the application services and cause a loss of availability (CAPEC-469 HTTP DoS). The issue has a CVSS v4.0 base score of 8.7 (AV:N/AC:L/PR:N/UI:N/VA:H) and was reported by Armis Labs. Affected devices running firmware below the fixed release are susceptible to remote DoS until patched or mitigated.

Overview

The vulnerability is an input-validation flaw in an MGW API that permits remote, unauthenticated actors to trigger repeated application-service crashes, producing a sustained availability impact. Affected product is Copeland LP E3 Supervisory Control firmware versions less than 2.31F01. Attack complexity is low, no privileges or user interaction are required, and the primary impact is high availability loss.

Remediation

Upgrade affected E3 Supervisory Control devices to the vendor-recommended fixed firmware release (per vendor guidance, upgrade to a version > 2.30F1). If immediate patching is not possible, restrict access to the device management/network interface (ETH 0) via segmentation (restricted VLAN or subnet) and network firewall rules, ensuring the management interface is never reachable from untrusted networks. Additionally, monitor device logs and network traffic for anomalous API calls and contact the vendor or Armis Labs for further mitigation advice.
