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
The BWOCXRUN.BwocxrunCtrl.1 control contains a method named OpenUrlToBufferTimeout. This method takes a URL as a parameter and returns its contents to the caller in JavaScript. The URLs are accessed in the security context of the current browser session. The control does not perform any URL validation and allows file:// URLs that access the local disk. The method can be used to open a URL (including file URLs) and read the URLs through JavaScript. This method could also be used to reach any arbitrary URL to which the browser has access.

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

The BWOCXRUN.BwocxrunCtrl.1 ActiveX control exposes an OpenUrlToBufferTimeout method lacking URL validation, allowing JavaScript in web pages to read arbitrary URLs including file:// URLs from the local filesystem through the browser's security context.

MitigationDisable the vulnerable ActiveX control via browser security settings or Group Policy, or remove the control from systems if unused.

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. Verify Advantech WebAccess installation
    Check for the presence of Advantech WebAccess in Windows Programs and Features (appwiz.cpl) or look for the installation directory, typically under C:\Advantech\WebAccess or similar paths.
    Affected if Advantech WebAccess is installed and the version matches 5.0, 6.0, 7.0, or 7.1 or earlier.
  2. Confirm ActiveX control is registered
    Search the Windows Registry under HKEY_CLASSES_ROOT\CLSID for the CLSID {6E3D12F1-7C98-11D4-9D7C-005004E89C82} (the CLSID for BWOCXRUN.BwocxrunCtrl.1), or use regsvr32 to check if the control DLL is registered.
    Affected if The BWOCXRUN.BwocxrunCtrl.1 ActiveX control is registered on the system.
  3. Identify the installed WebAccess version
    Locate the WebAccess version information in the Windows Registry under HKEY_LOCAL_MACHINE\SOFTWARE\Advantech\WebAccess\Version or within the installation folder's version metadata.
    Affected if The installed version is 5.0, 6.0, 7.0, 7.1, or any version <= 7.1.
  4. Check if ActiveX control is enabled in browser
    In Internet Explorer, navigate to Tools > Internet Options > Security > Custom Level, and verify if the setting for 'Run ActiveX controls and plugins' is enabled or if the specific BWOCXRUN control is listed in the 'Manage Add-ons' dialog.
    Affected if The ActiveX control is allowed to run in the browser security zone used to access untrusted web content.

A user is affected if Advantech WebAccess version 5.0, 6.0, 7.0, or 7.1 (or earlier than 7.1) is installed with the BWOCXRUN.BwocxrunCtrl.1 ActiveX control registered and permitted to run in the browser.
