Priority P2 78 critical 10 CVSS 3.1

AV N AC L PR N UI N S C C H I H A H

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

Detection & IOCs extracted from sources · hover to see the quote

• → The vulnerability targets specific API endpoints that do not properly enforce user authentication — monitor for unauthenticated requests to API endpoints on Siemens Industrial Edge devices, especially those that succeed without valid credentials ↗
• → Exploitation is classified as Authorization Bypass Through User-Controlled Key (CWE-639) — look for API requests where a user identity/key is supplied in the request without a corresponding valid authentication token or session ↗
• → Successful exploitation requires the attacker to know a legitimate username — monitor for reconnaissance activity (e.g., user enumeration attempts) against Industrial Edge device management interfaces prior to API abuse ↗
• → The attack vector is network-based with no privileges required and no user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) — alert on unauthenticated remote connections to management APIs of affected Siemens Industrial Edge devices from untrusted network segments ↗

• · The specific API endpoint paths that are improperly authenticated are not disclosed in the available advisories — detection rules cannot target specific URL paths without further vendor technical detail ↗
