CVE-2020-8601
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 · uneditedTrend Micro Vulnerability Protection 2.0 is affected by a vulnerability that could allow an attack to use the product installer to load other DLL files located in the same directory.
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 a DLL hijacking vulnerability in the Trend Micro Vulnerability Protection 2.0 installer. The installer loads DLL files from its own directory without proper path validation, allowing an attacker to place a malicious DLL in the same directory as the installer to achieve arbitrary code execution with the privileges of the installer process.

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 the Trend Micro Vulnerability Protection 2.0 installer is presentSearch for the installer executable (typically named something like 'TMVPSetup.exe' or 'TrendMicroVulnerabilityProtectionSetup.exe') on the system using file search utilities or checking common download directoriesAffected if The installer executable version 2.0 is found on the system
-
Locate the installer directory and list all DLL files presentNavigate to the directory containing the installer and enumerate all .dll files in that locationAffected if DLL files exist in the same directory as the installer, as the installer may load these without path validation
-
Verify the installed product versionCheck the installed version of Trend Micro Vulnerability Protection through the Windows registry (HKLM\SOFTWARE\TrendMicro\VulnerabilityProtection) or the program's About/Help sectionAffected if The installed version is exactly 2.0 (build numbers may vary)
-
Check for DLLs that could be hijacked in the installer directoryReview the DLL files in the installer directory for any that are unsigned, unexpectedly named, or match commonly hijacked DLL names (such as version.dll, profapi.dll, or crypt32.dll)Affected if Unsigned or suspicious DLL files are present alongside the installer executable
A user is affected if they have the version 2.0 installer present on their system with DLL files in the same directory that could be replaced by an attacker for arbitrary code execution.

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 dataReplace relative DLL loading with absolute paths or use Windows secure DLL loading APIs (SetDllDirectory with empty string, or SafeDllSearchMode) to prevent the installer from loading DLLs from its current directory. Rebuild and sign the installer with the corrected code.
