Siemens Industrial Edge Devices Weak Authentication (CVE-2024-54092)

critical Tenable OT Security Plugin ID 503757

Synopsis

The remote OT asset is affected by a vulnerability.

Description

Affected devices do not properly enforce user authentication on specific API endpoints when identity federation is used. This could facilitate an unauthenticated remote attacker to circumvent authentication and impersonate a legitimate user. Successful exploitation requires that identity federation is currently or has previously been used and the attacker has learned the identity of a legitimate user.

This plugin only works with Tenable.ot.

Siemens has identified the following specific workarounds and mitigations users can apply to reduce risk:

- SCALANCE LPE9413 (6GK5998-3GS01-2AC2), SIMATIC IPC427E Industrial Edge Device: Currently no fix is available
- Industrial Edge Virtual Device: Update to V1.21.1-1-a or later version
- Industrial Edge Own Device (IEOD): Update to V1.21.1-1-a or later version
- SIMATIC IPC BX-39A Industrial Edge Device, SIMATIC IPC BX-59A Industrial Edge Device, SIMATIC IPC127E Industrial Edge Device, SIMATIC IPC227E Industrial Edge Device, SIMATIC IPC847E Industrial Edge Device: Update to V3.0 or later version
- Ensure network access to affected products is limited to trusted parties only

As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens' operational guidelines for industrial security and following recommendations in the product manuals.
