Who should care

Organizations operating Siemens SIMATIC RFID systems in manufacturing, logistics, and industrial automation environments should prioritize this update. Security teams managing OT/ICS networks, asset owners with RFID-enabled supply chain operations, and compliance officers responsible for industrial cybersecurity frameworks should assess exposure and apply mitigations.

Technical summary

The affected Siemens SIMATIC RFID reader firmware contains a hidden configuration parameter that enables debug functionality. When activated, this functionality exposes internal deployment configuration details to authenticated users. The vulnerability requires network access and low privileges to exploit, with a CVSS 3.1 base score of 4.3 (MEDIUM). The attack complexity is low, and no user interaction is required. Impact is limited to low integrity impact with no direct confidentiality or availability effects, though information gained could facilitate further attacks.

Defensive priority

Recommended defensive actions

  • Review inventory for affected Siemens SIMATIC RFID reader models and apply vendor-supplied firmware updates: RF610R/RF615R/RF650R/RF680R/RF685R readers to V4.2 or later; RF1140R/RF1170R to V1.1 or later; RF166C/RF185C/RF
  • 186C/RF186CI/RF188C/RF188CI to V2.2 or later; RF360R to V2.2 or later
  • Restrict network access to affected RFID readers to authorized personnel only
  • Monitor for unauthorized configuration changes or unexpected diagnostic output
  • Apply defense-in-depth strategies per CISA ICS recommended practices for industrial control systems

Evidence notes

The vulnerability description and affected product list are derived from CISA CSAF advisory ICSA-24-256-07, which references Siemens security advisory SSA-765405. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) indicates network-accessible attack vector with low attack complexity, requiring low privileges and resulting in low integrity impact with no confidentiality or availability impact.
