Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Multiple stack-based buffer overflows in (1) COM and (2) ActiveX controls in ABB WebWare Server, WebWare SDK, Interlink Module, S4 OPC Server, QuickTeach, RobotStudio S4, and RobotStudio Lite allow remote attackers to execute arbitrary code via crafted input data.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Multiple stack-based buffer overflow vulnerabilities exist in ABB's COM and ActiveX controls across WebWare Server, WebWare SDK, Interlink Module, S4 OPC Server, QuickTeach, RobotStudio S4, and RobotStudio Lite. Remote attackers can execute arbitrary code by sending crafted input data to these vulnerable controls.

MitigationApply all available vendor patches for the affected ABB products. Until patches are available, restrict network exposure of vulnerable controls and disable ActiveX controls in untrusted contexts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed ABB products
    Check for presence of ABB software by looking in Program Files for folders named ABB, or search for executable files associated with the affected products: Interlink Module, QuickTeach, RobotStudio, S4 OPC Server, WebWare SDK, WebWare Server. Use 'Get-ItemProperty' or 'dir' to search installation directories.
    Affected if Any of the seven affected ABB products (Interlink Module, QuickTeach, RobotStudio Lite, RobotStudio S4, S4 OPC Server, WebWare SDK, WebWare Server) are installed on the system
  2. Locate COM and ActiveX controls
    Check Windows Registry for registered COM components from ABB. Look in HKLM\SOFTWARE\Classes for CLSIDs with vendor 'ABB' or product-related identifiers. Use 'reg query' commands to search for ABB entries in the registry.
    Affected if COM or ActiveX controls from the affected ABB products are registered on the system (the vulnerability exists in these controls regardless of version)
  3. Check for vulnerable DLL files
    Search for DLL files associated with the affected products in installation directories. Common ABB control DLLs may be named with product identifiers like 'ABB', 'WebWare', 'Interlink', 'RobotStudio', or 'QuickTeach'. Use 'Get-ChildItem' or 'dir' to search.
    Affected if DLL files implementing the vulnerable COM/ActiveX controls are present on the system
  4. Verify network exposure
    Check if the system is accessible over network on ports used by the affected products (WebWare Server typically uses HTTP ports, S4 OPC Server uses OPC ports). Use 'netstat -an' to list listening ports and correlate with running ABB services.
    Affected if The system with ABB products is network-accessible and the vulnerable controls can receive crafted input from remote attackers

A user is affected if any of the seven ABB products (Interlink Module, QuickTeach, RobotStudio Lite, RobotStudio S4, S4 OPC Server, WebWare SDK, WebWare Server) are installed, as all versions contain the vulnerable COM/ActiveX controls.
