IndraDrive FWA-INDRV*-MP*: Uncontrolled Resource Consumption

Published Updated By the CyberSecBulletin desk

CVE-2024-48989 is a high-severity uncontrolled resource consumption vulnerability in IndraDrive FWA-INDRV*-MP* from Bosch Rexroth, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 20V36 as the first without the flaw, so updating IndraDrive FWA-INDRV*-MP* to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.49% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update IndraDrive FWA-INDRV*-MP* to 20V36 or a later version.
  2. Update indradrive_fwa_indrv_mp to 20v36 or a later version.
  3. Read the advisory on psirt.bosch.com for workarounds and exact fixed builds.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Uncontrolled Resource Consumption

The product does not properly control the allocation and maintenance of a limited resource.

How developers prevent this class of flaw

  • Ensure that protocols have specific limits of scale placed on them.
  • Ensure that all failures in resource allocation place the system into a safe posture.
