Published severityHighOperational priority:Medium, lowered one band.downgradedsince 21 Apr 2025

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.24% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Siemens SIMATIC PCS 7 V8.2 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: As exposure requiresRemediation target: Within 365 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 8 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

What, why and how

A vulnerability has been identified in SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3 UC06), SIMATIC PCS 7 V9.1 (All versions < V9.1 SP1 UC01), SIMATIC WinCC Runtime Professional V16 and earlier (All versions), SIMATIC WinCC Runtime Professional V17 (All versions < V17 Upd4), SIMATIC WinCC V7.3 (All versions), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Update 21), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 8). A missing printer configuration on the host could allow an authenticated attacker to escape the WinCC Kiosk Mode.

A vulnerability has been identified in SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3 UC06), SIMATIC PCS 7 V9.1 (All versions < V9.1 SP1 UC01), SIMATIC WinCC Runtime Professional V16 and earlier (All versions), SIMATIC WinCC Runtime Professional V17 (All versions < V17 Upd4), SIMATIC WinCC V7.3 (All versions), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Update 21), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 8). A missing printer configuration on the host could allow an authenticated attacker to escape the WinCC Kiosk Mode.

Why

The product initializes or sets a resource with a default that is intended to be changed by the product's installer, administrator, or maintainer, but the default is not secure.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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.

Likely attack path

CWE-1188 ↗

CWE-1188: Initialization of a Resource with an Insecure Default. The product initializes or sets a resource with a default that is intended to be changed by the product's installer, administrator, or maintainer, but the default is not secure.

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
An authoritative update reference is available, but the fixed version is not recorded in the structured CVE fields. Check the linked vendor advisory for the applicable release.
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. Limit untrusted access and use least privilege until authoritative guidance is available.
