IE-SW-VL05M-5TX: Insufficient Resource Pool

Published Updated By the CyberSecBulletin desk

CVE-2025-41653 is a high-severity insufficient resource pool vulnerability in IE-SW-VL05M-5TX from Weidmueller, 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 3.6.32 as the first without the flaw, so updating IE-SW-VL05M-5TX to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.62% chance of exploitation within 30 days, higher than 50% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

Official description

An unauthenticated remote attacker can exploit a denial-of-service vulnerability in the device's web server functionality by sending a specially crafted HTTP request with a malicious header, potentially causing the server to crash or become unresponsive.

The underlying weakness: Insufficient Resource Pool

The product's resource pool is not large enough to handle peak demand.

How developers prevent this class of flaw

  • Do not perform resource-intensive transactions for unauthenticated users and/or invalid requests.
  • Consider implementing a velocity check mechanism which would detect abusive behavior.
  • Consider load balancing as an option to handle heavy loads.
