Who should care

Organizations using IDEC WindLDR or WindO/I-NV4 for PLC and HMI programming in industrial automation environments. This includes manufacturing facilities, utilities, and other industrial sectors relying on IDEC control systems. Security teams responsible for OT/ICS asset management and engineering workstation protection should prioritize patching.

Technical summary

The vulnerability involves cleartext storage of sensitive user authentication information in IDEC Corporation's WindLDR PLC programming software and WindO/I-NV4 HMI programming software. An attacker with network access could potentially obtain authentication credentials due to this insecure storage practice. The attack requires high complexity but can be executed without privileges or user interaction. The confidentiality impact is rated high, though integrity and availability are not affected. This vulnerability is particularly relevant in operational technology environments where engineering workstations may have privileged access to industrial control systems.

Defensive priority

Recommended defensive actions

  • Apply vendor software updates: upgrade WindLDR to Ver.9.2.0 and WindO/I-NV4 to Ver.3.1.0
  • Review IDEC Corporation security advisory for additional mitigation guidance
  • Implement network segmentation for industrial control systems per CISA ICS recommended practices
  • Apply defense-in-depth strategies for ICS environments
  • Monitor for unauthorized access attempts to engineering workstations running affected software

Evidence notes

CISA CSAF advisory ICSA-24-263-03 published 2024-09-19 identifies cleartext storage of sensitive authentication information in IDEC WindLDR ≤9.1.0 and WindO/I-NV4 ≤3.0.1. CVSS 3.1 vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N yields score 5.9 (MEDIUM). Vendor fixes released: WindLDR Ver.9.2.0 and WindO/I-NV4 Ver.3.1.0.
