CVE-2024-33578
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 · uneditedA DLL hijack vulnerability was reported in Lenovo Leyun that could allow a local attacker to execute code with elevated privileges.
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 confidenceA DLL hijacking vulnerability exists in Lenovo Leyun where the application insecurely loads Dynamic Link Libraries, potentially allowing a local attacker to place a malicious DLL in a search path location that the application will load, resulting in code execution with elevated privileges.

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.
-
Identify if Lenovo Leyun is installedSearch for Lenovo Leyun installation in standard program directories: check C:\Program Files\Lenovo\Leyun and C:\Program Files (x86)\Lenovo\Leyun, or use command: Get-ChildItem -Path 'C:\Program Files','C:\Program Files (x86)' -Recurse -Directory -ErrorAction SilentlyContinue | Where-Object {$_.Name -eq 'Leyun'}Affected if Lenovo Leyun directory exists on the system
-
Locate the main executableFind Leyun.exe within the installation directory using: dir /s "C:\Program Files\Lenovo\Leyun\Leyun.exe" or PowerShell: Get-ChildItem -Path 'C:\Program Files\Lenovo\Leyun' -Recurse -Filter 'Leyun.exe'Affected if Leyun.exe is found in the installation path
-
Determine installed versionRight-click Leyun.exe, select Properties, and view the Details tab for version information, or run: (Get-Item 'C:\Program Files\Lenovo\Leyun\Leyun.exe').VersionInfoAffected if Version information cannot be obtained or shows an affected version of Lenovo Leyun prior to the CVE patch
-
Check for insecure DLL loading behaviorMonitor Lenovo Leyun execution using Process Monitor (ProcMon) from Sysinternals - filter by Process Name = Leyun.exe and Operation = Load Image, then observe if DLLs are loaded from current directory, application directory, or PATH locations without full path specificationAffected if The application loads DLLs from directories writable by lower-privilege users or does not use absolute explicit paths for DLL loading
System is affected if Lenovo Leyun is installed and exhibits DLL hijacking behavior by loading DLLs from insecure search paths rather than using absolute explicit paths with Safe DLL Search Mode enabled.

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 dataRemediate by implementing secure DLL loading practices: use absolute explicit paths for DLLs, enable Safe DLL Search Mode, remove insecure search paths, and verify all loaded DLLs are digitally signed.
