Summary

Bosch Rexroth IndraDrive FWA-INDRV-MP firmware versions prior to 20V36 contain a vulnerability (CWE-400) that allows an attacker to send arbitrary UDP messages to cause a denial-of-service condition, rendering the device unresponsive. This affects motor drive controllers used across industrial applications.

What this means
What could happen
An attacker on the network can send UDP packets to cause the IndraDrive controller to become unresponsive, interrupting motor drive operations and any dependent industrial processes.
Who's at risk
Organizations operating Bosch Rexroth IndraDrive motor controllers in manufacturing, water/wastewater treatment, power generation, and pulp-and-paper facilities should assess this vulnerability. Affected firmware versions prior to 20V36 are at risk.
How it could be exploited
An attacker with network access to the IndraDrive device sends specially crafted UDP messages to trigger a denial-of-service condition. No authentication or special configuration is required.
Prerequisites
  • Network access to the IndraDrive device over UDP
  • No credentials or authentication required
