CVE-2024-31856 CyberPower CVE debrief

CVE-2024-31856 is a high-severity vulnerability in CyberPower PowerPanel Business versions 4.9.0 and earlier. The flaw allows an attacker with certain MQTT permissions to craft malicious messages that can be broadcast to all Power Panel devices in an environment. Successful exploitation enables SQL injection, arbitrary file writes, and remote code execution. The vulnerability was published on May 2, 2024, and the advisory was last modified on August 7, 2025. CyberPower has released PowerPanel Business version 4.10.1 to address these issues. Organizations should prioritize patching, especially in environments where PowerPanel Business manages critical power infrastructure.

Who should care

Organizations using CyberPower PowerPanel Business for UPS and power infrastructure management, particularly in data centers, industrial facilities, and critical infrastructure environments. Security teams responsible for OT/ICS asset protection and MQTT-based IoT deployments should prioritize this vulnerability.

Technical summary

The vulnerability exists in the MQTT message handling component of PowerPanel Business. An authenticated attacker with specific MQTT permissions can publish malicious messages that are processed by all connected Power Panel devices. The message parsing logic fails to properly sanitize input, allowing SQL syntax injection. This initial access vector can be chained to achieve arbitrary file writes on the underlying system and ultimately execute remote code. The attack requires network access to the MQTT broker and valid credentials with message publishing permissions.

Defensive priority

high

Recommended defensive actions

  • Update CyberPower PowerPanel Business to version 4.10.1 or later
  • Review and restrict MQTT broker permissions to limit message publishing capabilities
  • Segment PowerPanel Business management interfaces from untrusted networks
  • Monitor for anomalous MQTT traffic targeting PowerPanel devices
  • Apply defense-in-depth strategies per CISA ICS recommended practices
