"The remote OT asset is affected by a vulnerability.");
  script_set_attribute(attribute:"description", value:
"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.

"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.

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.
