Siemens Teamcenter V12.4 — Privilege Defined With Unsafe Actions

Siemens · Teamcenter V12.4

7.1HighCVSS 3.1
Recommended action
Patch only the product branches with a verified fix

High technical severity; prioritise exposed affected systems while verifying vendor guidance. Verified remediation exists for at least one product or source, but 4 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.58% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Siemens Teamcenter V12.4 and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 30 daysRemediation target: Within 180 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 4 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Summary
The "surrogate" functionality on the user profile of the application does not perform sufficient access control that could lead to an account takeover. Any profile on the application can perform this attack and access any other user assigned tasks via the "inbox/surrogate tasks".

01

What, why and how

A vulnerability has been identified in Teamcenter V12.4 (All versions < V12.4.0.8), Teamcenter V13.0 (All versions < V13.0.0.7), Teamcenter V13.1 (All versions < V13.1.0.5), Teamcenter V13.2 (All versions < 13.2.0.2). The "surrogate" functionality on the user profile of the application does not perform sufficient access control that could lead to an account takeover. Any profile on the application can perform this attack and access any other user assigned tasks via the "inbox/surrogate tasks".

What

A vulnerability has been identified in Teamcenter V12.4 (All versions < V12.4.0.8), Teamcenter V13.0 (All versions < V13.0.0.7), Teamcenter V13.1 (All versions < V13.1.0.5), Teamcenter V13.2 (All versions < 13.2.0.2). The "surrogate" functionality on the user profile of the application does not perform sufficient access control that could lead to an account takeover. Any profile on the application can perform this attack and access any other user assigned tasks via the "inbox/surrogate tasks".

Why

A particular privilege, role, capability, or right can be used to perform unsafe actions that were not intended, even when it is assigned to the correct entity.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may bypass an access boundary or take over an account.

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.

CWE-267 ↗

CWE-267: Privilege Defined With Unsafe Actions. A particular privilege, role, capability, or right can be used to perform unsafe actions that were not intended, even when it is assigned to the correct entity.

Patch and workaround

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Fix availability varies by product
Affected
Fixed
Update to V12.4.0.8 or later version
Action
Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
Workaround
No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
