CVE-2019-20769
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 · uneditedAn issue was discovered in LG PC Suite for LG G3 and earlier (aka LG PC Suite v5.3.27 and earlier). DLL Hijacking can occur via a Trojan horse DLL in the current working directory. The LG ID is LVE-MOT-190001 (November 2019).
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 confidenceLG PC Suite versions 5.3.27 and earlier are vulnerable to DLL hijacking. The application loads DLLs from the current working directory without proper path validation, allowing an attacker to place a malicious DLL in the same directory as the executable. When a user runs the application from a directory containing the trojan horse DLL, the attacker gains 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.
-
Locate LG PC Suite installationSearch for 'LG PC Suite' executable on the system. Common installation paths include C:\Program Files\LG PC Suite or C:\Program Files (x86)\LG PC Suite. Also check Start Menu shortcuts and the Windows uninstall registry (HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall).Affected if LG PC Suite is installed on the system.
-
Determine installed versionRight-click the LG PC Suite executable (e.g., LGPCSuite.exe) and select Properties, then view the Details tab for the File Version. Alternatively, open the Windows uninstall list and find LG PC Suite to see the installed version.Affected if The displayed version is 5.3.27 or earlier.
-
Check for newer patched versionIn the LG PC Suite application, go to Help > About or check the program menu for version information. Compare against the fixed version 5.3.28.Affected if No version is displayed or the version shown is <= 5.3.27, indicating the vulnerable version is installed.
-
Inspect application directory contentsNavigate to the directory where LG PC Suite is installed. Examine all DLL files present in that folder. Look for any DLLs that are not original LG PC Suite components or appear suspicious/unexpected.Affected if Unexpected or unsigned DLL files exist in the application directory, which could indicate exploitation or tampering.
If LG PC Suite version 5.3.27 or earlier is installed and running, the system is vulnerable to DLL hijacking attacks when the application is executed from directories containing attacker-controlled DLLs.

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 dataUsers should upgrade to LG PC Suite v5.3.28 or later. Until then, avoid running LG PC Suite from untrusted or shared directories, and ensure the application directory contains only trusted files.
