4 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • SIMATIC PDM Maintenance Station V5.0 < V5.0.2
  • SIMATIC WinCC OA V3.18 < V3.18.032
  • SIMATIC WinCC OA V3.19 < V3.19.020
  • SIMATIC WinCC OA V3.20 < V3.20.008
Summary
Wibu CodeMeter before 8.30a sometimes allows privilege escalation immediately after installation (before a logoff or reboot). For exploitation, there must have been an unprivileged installation with UAC, and the CodeMeter Control Center component must be installed, and the CodeMeter Control Center component must not have been restarted. In this scenario, the local user can navigate from Import License to a privileged instance of Windows Explorer.
Remediation
Update to V3.18 P032 or later version

What, why and how

Wibu CodeMeter before 8.30a sometimes allows privilege escalation immediately after installation (before a logoff or reboot). For exploitation, there must have been an unprivileged installation with UAC, and the CodeMeter Control Center component must be installed, and the CodeMeter Control Center component must not have been restarted. In this scenario, the local user can navigate from Import License to a privileged instance of Windows Explorer.

What

Wibu CodeMeter before 8.30a sometimes allows privilege escalation immediately after installation (before a logoff or reboot). For exploitation, there must have been an unprivileged installation with UAC, and the CodeMeter Control Center component must be installed, and the CodeMeter Control Center component must not have been restarted. In this scenario, the local user can navigate from Import License to a privileged instance of Windows Explorer.

Why

The elevated privilege level required to perform operations such as chroot() should be dropped immediately after the operation is performed.

How

An attacker operating through local access may attempt exploitation with elevated privileges. If successful, the issue may gain additional privileges.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Weakness

CWE-272 ↗

CWE-272: Least Privilege Violation. The elevated privilege level required to perform operations such as chroot() should be dropped immediately after the operation is performed.

Official advisory
NCSC-NL · Dutch · NCSC-2026-0346Kwetsbaarheden verholpen in Siemens producten

Wibu CodeMeter versions prior to 8.30a contain a privilege escalation vulnerability occurring immediately after installation when installed without elevated privileges, enabling local users to access a privileged Windows Explorer instance via the CodeMeter Control Center before restart.

Official advisory
NCSC-NL · Dutch · NCSC-2025-0246Kwetsbaarheden verholpen in Siemens producten

De kwetsbaarheden stellen een kwaadwillende mogelijk in staat aanvallen uit te voeren die kunnen leiden tot de volgende categorieën schade: * Denial-of-Service (DoS) * Cross-Site Scripting * Manipulatie van gegevens * Omzeilen van een beveiligingsmaatregel * (Remote) code execution (SYSTEM rechten) * (Remote) code execution (Gebruikersrechten) * Toegang tot gevoelige gegevens * Verhogen van rechten De kwaadwillende heeft hiervoor toegang nodig tot de productieomgeving. Het is goed gebruik een dergelijke omgeving niet publiek toegankelijk te hebben.
