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
NREL BEopt 2.8.0.0 contains a DLL hijacking vulnerability that allows attackers to load arbitrary libraries by tricking users into opening application files from remote shares. Attackers can exploit insecure library loading of sdl2.dll and libegl.dll by placing malicious libraries on WebDAV or SMB shares to execute unauthorized code.

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 confidence

NREL BEopt 2.8.0.0 is vulnerable to DLL hijacking through insecure loading of sdl2.dll and libegl.dll. Attackers can place malicious DLLs on WebDAV or SMB shares and trick users into opening application files from those remote locations, causing arbitrary code execution.

MitigationImplement secure DLL loading by using absolute paths, disabling DLL search order loading from current directory, and/or digitally signing all required DLLs to prevent unauthorized library injection.

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 BEopt installation and version
    Locate NREL BEopt on the system and determine its exact version number from the application's About, Help, or version information dialog, or by checking the executable's file properties
    Affected if The installed version matches 2.8.0.0 exactly
  2. Check if application is launched from network locations
    Examine the installation path and determine whether BEopt is being run from a local drive or from a remote WebDAV/SMB share by observing the path in file explorer or command prompt
    Affected if BEopt is launched from or its files are accessed via UNC paths, mapped network drives, or WebDAV URLs
  3. Identify vulnerable DLL locations
    Check the BEopt application directory for the presence of sdl2.dll and libegl.dll files, and verify whether these DLLs exist in locations writable by untrusted users
    Affected if sdl2.dll or libegl.dll exist in the application directory and could be replaced by a malicious version
  4. Test DLL search order behavior
    Attempt to launch BEopt from a directory containing a specially crafted sdl2.dll or libegl.dll to observe if the application loads the DLL from the current directory instead of using an absolute path
    Affected if The application loads DLLs from the current working directory rather than from a secure, absolute path

A system is affected if NREL BEopt version 2.8.0.0 is installed and can be launched from or loads DLLs from remote/network locations where attackers could place malicious sdl2.dll or libegl.dll files
