CVE-2018-3667
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 · uneditedInstallation tool IPDT (Intel Processor Diagnostic Tool) 4.1.0.24 sets permissions of installed files incorrectly, allowing for execution of arbitrary code and potential privilege escalation.
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 confidenceThe Intel Processor Diagnostic Tool (IPDT) version 4.1.0.24 installer sets overly permissive file permissions on installed executables, allowing unprivileged local users to modify or replace these files. This insecure permission configuration enables arbitrary code execution with elevated privileges when the modified files are subsequently executed.

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.
-
Determine if IPDT is installedSearch for the Intel Processor Diagnostic Tool in system programs or check for its executable in typical installation locations such as Program Files directoriesAffected if The tool is found on the system
-
Identify the installed versionRight-click the IPDT executable, select Properties, and view the File Version or Details tab; alternatively, run the executable with a version flag if supportedAffected if The version is exactly 4.1.0.24
-
Locate the installation directoryRight-click the IPDT shortcut or executable, select Open file location, and note the full path to the folder containing the main executableAffected if The executables reside in a user-accessible directory
-
Inspect file permissions on executablesRight-click each executable file in the IPDT installation folder, select Properties, then the Security tab; examine the permissions for Users or authenticated users groupAffected if Users or authenticated users have Write or Modify permissions to the executable files
-
Verify write access for unprivileged usersIf possible, attempt to create or modify a test file in the installation directory using a standard non-admin user account, or review the Effective Permissions for a standard user account via the Security tabAffected if A standard unprivileged user can write to or modify files in the IPDT installation directory
A system is affected if Intel Processor Diagnostic Tool version 4.1.0.24 is installed AND executable files in its installation directory grant Write or Modify permissions to unprivileged users, allowing potential code replacement.

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 dataAudit and correct file permissions on IPDT installation directories to restrict write access; if a patched version is available, upgrade to the fixed release; remove the tool if not needed.
