Integer overflow in an unspecified ActiveX control in SVUIGrd.ocx in ARC Informatique PcVue 6.0 through 10.0, FrontVue, and PlantVue allows remote attackers to execute arbitrary code via a large value for an integer parameter, leading to a buffer overflow.

Analyst readout for executives and security teams

Plain-English summary

This CVE affects older ARC Informatique PcVue-family industrial control products. A vulnerable ActiveX control can mishandle an oversized integer value, causing memory corruption that may allow arbitrary code execution. For executives, the concern is legacy SCADA workstation compromise, not ordinary internet server exposure.

Executive priority

Treat this as a legacy industrial control risk with high potential impact. Prioritize asset discovery first, then vendor-supported remediation or isolation for any affected SCADA workstations.

Technical view

CVE-2011-4043 is an integer overflow in an unspecified ActiveX control in SVUIGrd.ocx affecting PcVue 6.0 through 10.0, FrontVue, and PlantVue. The described impact is remote arbitrary code execution through a large integer parameter that leads to a buffer overflow.

Likely exposure

Exposure is most likely in legacy industrial control environments running PcVue 6.0-10.0, FrontVue, or PlantVue with SVUIGrd.ocx present. Evidence provided does not define broader affected versions, CPEs, or supported configurations.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. The vulnerability is still serious because the published impact is remote code execution against an ActiveX component in SCADA-related software.

Researcher notes

The source bundle lacks CVSS, CWE mapping, precise control name, patch details, and exploit telemetry. Analysis should remain bounded to the published description and the listed US-CERT and vendor references.

Mitigation direction

  • Check ARC Informatique/PcVue guidance for the supported fix or upgrade path.
  • Prioritize replacement or isolation of PcVue 6.0-10.0, FrontVue, and PlantVue systems.
  • Restrict untrusted content on engineering and HMI workstations using ActiveX components.
  • Segment SCADA workstations from general user networks and internet browsing paths.
  • Do not disable SVUIGrd.ocx without confirming operational impact with the vendor.

Validation and detection

  • Inventory systems for PcVue 6.0-10.0, FrontVue, PlantVue, and SVUIGrd.ocx.
  • Confirm installed versions against vendor advisories and support guidance.
  • Review whether affected workstations can process untrusted web or document content.
  • Check compensating controls for SCADA workstation segmentation and browsing restrictions.
  • Track remediation status separately for unsupported or business-critical legacy systems.
