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
An information disclosure vulnerability exists when Internet Explorer improperly handles objects in memory.An attacker who successfully exploited this vulnerability could test for the presence of files on disk, aka 'Internet Explorer Information Disclosure Vulnerability'.

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

This is an information disclosure vulnerability in Internet Explorer where improper handling of memory objects allows an attacker to test for the existence of specific files on the local disk. The vulnerability does not allow reading file contents, only checking whether files are present, but could be used for reconnaissance to determine if targeted files (like configuration files, credentials, or other sensitive data) exist on a victim's system.

MitigationApply the relevant Microsoft security update for CVE-2019-0676. Since Internet Explorer is deprecated, organizations should migrate to modern browsers and consider disabling IE entirely where possible to reduce attack surface.

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. Confirm Internet Explorer installation
    Locate iexplore.exe in the file system, typically found in %ProgramFiles%\Internet Explorer\iexplore.exe or %ProgramFiles(x86)%\Internet Explorer\iexplore.exe on 64-bit systems
    Affected if The file exists on the system, indicating Internet Explorer is installed
  2. Retrieve Internet Explorer version
    Run 'reg query "HKLM\SOFTWARE\Microsoft\Internet Explorer" /v Version' or right-click iexplore.exe and select Properties > Details to view the Product Version
    Affected if The version returned is 10.x or 11.x (exactly version 10 or version 11)

The system is affected if Internet Explorer version 10 or version 11 is installed and the security update for CVE-2019-0676 has not been applied.
