CVE-2024-42405
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 · uneditedUncontrolled search path for some Intel(R) Quartus(R) Prime Software before version 23.1.1 Patch 1.01std may allow an authenticated user to potentially enable escalation of privilege via local 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 confidenceThis is an uncontrolled search path (DLL/library hijacking) vulnerability in Intel Quartus Prime Software. An authenticated local attacker can place a malicious library in a directory that the application searches when loading dependencies, potentially causing the application to execute arbitrary code with elevated privileges. This requires local access and valid user credentials.

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.
-
Verify Intel Quartus Prime installationLook for Quartus Prime in common installation directories such as C:\intelFPGA\ or C:\Program Files\Intel\, or check for the quartus.exe executable in the system.Affected if Intel Quartus Prime Software is found on the system.
-
Determine installed Quartus Prime versionLocate the quartus.exe file, right-click and view Properties, or run 'quartus.exe --version' from the installation directory to obtain the exact version number.Affected if The installed version is earlier than 23.1.1 Patch 1.01std.
-
Identify the application directory and permissionsCheck the permissions on the Quartus Prime installation directory (e.g., the intelFPGA folder). Use Windows Explorer Properties > Security or icacls from command prompt to see if standard users have Write or Modify permissions.Affected if Non-admin users have Write or Modify permissions to the Quartus Prime installation directory or its subdirectories.
-
Examine system PATH for user-writable directoriesOpen System Properties > Environment Variables and review the PATH variable. Check each directory listed before the Quartus path for write access by standard users using icacls or file permissions.Affected if User-writable directories (such as temp folders, user profiles, or writable network shares) appear in the system or user PATH before the Quartus installation directory.
-
Review DLL search order for the applicationUse Process Monitor or similar tooling to trace DLL loading when launching Quartus.exe. Alternatively, check if the application directory contains any relative path dependencies that could be satisfied by libraries in writable PATH directories.Affected if The application loads DLLs from directories that non-privileged users can modify.
The system is affected if Intel Quartus Prime version earlier than 23.1.1 Patch 1.01std is installed and either the application directory or any PATH directory searched before it is writable by standard users.

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.
dbcve · scopedUpgrade to Intel Quartus Prime Software version 23.1.1 Patch 1.01std or later. As a compensating control, ensure the application runs from secure, non-writable directories and that user-writable directories are not included in the system PATH before the legitimate application directories.
Intel Quartus Prime 23.1.1 Patch 1.01std or later
- Download Intel Quartus Prime version 23.1.1 Patch 1.01std or later from the official Intel website
- Uninstall the current version of Intel Quartus Prime software or verify the existing installation can accept the patch
- Install the downloaded fixed version (23.1.1 Patch 1.01std or later) following Intel's installation instructions
- Verify the installation completed successfully and the software runs without errors
- Confirm the DLL hijacking vulnerability is resolved by ensuring the software loads DLLs from trusted, controlled paths only
