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
Stack-based buffer overflow in the HMIWeb Browser HSCDSPRenderDLL ActiveX control in Honeywell Process Solutions (HPS) Experion R2xx, R30x, R31x, and R400.x; Honeywell Building Solutions (HBS) Enterprise Building Manager R400 and R410.1; and Honeywell Environmental Combustion and Controls (ECC) SymmetrE R410.1 allows remote attackers to execute arbitrary code via unspecified vectors.

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 · high confidence

Stack-based buffer overflow vulnerability in the HMIWeb Browser HSCDSPRenderDLL ActiveX control used in Honeywell industrial process control and building management systems. The overflow allows remote attackers to execute arbitrary code by sending specially crafted input to the ActiveX control.

MitigationApply vendor-supplied patches for affected Experion, Enterprise Building Manager, and SymmetrE versions; consider disabling the ActiveX control if patches are unavailable; implement network segmentation to limit exposure of affected systems.

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 Honeywell industrial or building management software
    Review installed programs on the system for Honeywell Experion, Enterprise Building Manager, or SymmetrE. Use Windows Programs and Features or the vendor's software inventory method to list installed Honeywell products.
    Affected if Honeywell Experion, Enterprise Building Manager, or SymmetrE software is installed on the system.
  2. Determine the exact version of the installed Honeywell software
    Access the software's about or version information, typically found in the application menu, control panel entry, or installation directory. Note the full version string including release designations such as r200, r300, r310, r400, r400.0, or r410.1.
    Affected if The installed version matches r200, r300, r310, r400, r400.0, or r410.1 for the respective product.
  3. Locate the HSCDSPRenderDLL ActiveX control
    Search the system for the file HSCDSPRenderDLL.dll. Typical locations may include the Honeywell software installation directory, Windows system folders, or HMIWeb-related directories. Use file search or review the software installation folder structure.
    Affected if The HSCDSPRenderDLL.dll file exists on the system, indicating the vulnerable ActiveX control is present.
  4. Check if the ActiveX control is registered or loadable
    Review browser settings or Windows registry for registered ActiveX controls. Check Internet Explorer or other browser ActiveX settings for HSCDSPRenderDLL, or examine the Windows registry under HKLM\SOFTWARE\Microsoft\Code Store Database\DistributedCOM or similar COM/ActiveX registration locations.
    Affected if The ActiveX control is registered and enabled in the browser or system, making it potentially reachable by web-based attack vectors.

The system is affected if any Honeywell Experion, Enterprise Building Manager, or SymmetrE version r200, r300, r310, r400, r400.0, or r410.1 is installed and the HSCDSPRenderDLL ActiveX control is present and enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor-supplied patches for affected Experion, Enterprise Building Manager, and SymmetrE versions; consider disabling the ActiveX control if patches are unavailable; implement network segmentation to limit exposure of affected systems.
