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.
