CVE-2017-8137
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 · uneditedHedEx Earlier than V200R006C00 versions has a dynamic link library (DLL) hijacking vulnerability due to calling the DDL file by accessing a relative path. An attacker could exploit this vulnerability to tamper with the DLL file, leading to DLL hijacking.
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 confidenceHedEx versions prior to V200R006C00 are vulnerable to DLL hijacking because the application loads dynamic link libraries using relative paths instead of absolute paths or secure search order. An attacker with write access to a directory in the DLL search path can place a malicious DLL that will be loaded by HedEx, resulting in arbitrary code execution with the privileges of the running user.

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 HedEx Lite installationSearch for HedEx Lite executables (hedex.exe, hedexlite.exe, or similar) on the system, typically found in Program Files or a custom installation directory. Check the file properties to confirm the product name.Affected if HedEx Lite executable is found on the system
-
Determine installed HedEx versionRight-click the HedEx executable, select Properties, and check the File Version or Product Version field. Alternatively, access Help > About in the HedEx application menu to view the version number.Affected if Version is below V200R006C00 (for example, any v200r005xx or earlier release)
-
Identify DLL search path directoriesUse Process Monitor or similar tool to monitor HedEx process startup and identify which directories the application searches for DLL files. Look for paths including the application directory, current working directory, and system directories.Affected if The application loads DLLs from relative paths rather than absolute paths
-
Check write permissions on DLL search pathReview file system permissions on directories in the DLL search path (particularly the application directory and current working directory). Use icacls or file explorer to verify which users or groups have write access to these locations.Affected if Untrusted users have write access to any directory in the DLL search path that gets loaded before system directories
User is affected if HedEx Lite version is below V200R006C00 AND untrusted users can write to directories in the application's DLL search path.

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 dataUpgrade HedEx to version V200R006C00 or later, which implements secure DLL loading. Alternatively, ensure the application runs from a directory where untrusted users cannot write files, or remove the current directory from the Windows DLL search order via manifest or registry settings.
