CVE-2006-6488
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 · uneditedStack-based buffer overflow in the DoModal function in the Dialog Wrapper Module ActiveX control (DlgWrapper.dll) before 8.4.166.0, as used by ICONICS OPC Enabled Gauge, Switch, and Vessel ActiveX, allows remote attackers to execute arbitrary code via a long (1) FileName or (2) Filter argument.
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 confidenceStack-based buffer overflow in the DoModal function of DlgWrapper.dll (versions before 8.4.166.0) allows remote code execution via overly long FileName or Filter arguments. The vulnerable ActiveX control is used in ICONICS OPC Enabled Gauge, Switch, and Vessel industrial automation components.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate DlgWrapper.dll and identify its versionSearch for DlgWrapper.dll on the system using file search tools, then right-click the file, select Properties, and examine the Version tab to obtain the File Version numberAffected if The file version is 8.4.165.0 or lower, or the version cannot be determined (older unversioned builds)
-
Confirm the ActiveX control is registeredOpen Windows Registry Editor and search for entries containing 'DlgWrapper' or the ActiveX component GUID under HKEY_CLASSES_ROOT\CLSID, or use the command 'regsvr32 /s DlgWrapper.dll' to check if registration succeedsAffected if The DlgWrapper ActiveX control is registered and present on the system
-
Check for ICONICS OPC industrial automation componentsSearch for ICONICS OPC Enabled Gauge, Switch, or Vessel components on the system, typically installed as part of the Iconics suite in program files or industrial automation directoriesAffected if Any of these affected components (Gauge, Switch, Vessel) are installed and reference the vulnerable DlgWrapper.dll
-
Verify the DoModal function is accessibleConfirm the ActiveX control can be invoked via web browsers or vulnerable application interfaces that pass FileName or Filter arguments to the DoModal functionAffected if The DoModal function of DlgWrapper.dll can be called with user-controlled string arguments
The system is affected if DlgWrapper.dll version is 8.4.165.0 or lower AND the ICONICS ActiveX control is registered and accessible on the system.

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 dataUpgrade DlgWrapper.dll to version 8.4.166.0 or later. If upgrading is not feasible, disable or remove the affected ActiveX control and implement network-level controls to block external exploitation vectors.
