CVE-2018-6218
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 Hijacking vulnerability in Trend Micro's User-Mode Hooking Module (UMH) could allow an attacker to run arbitrary code on a vulnerable system.
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 in Trend Micro's User-Mode Hooking Module (UMH) allows attackers to load a malicious DLL instead of the legitimate one, leading to arbitrary code execution with the privileges of the affected Trend Micro component.

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 installed Trend Micro productCheck installed programs on the system for any Trend Micro security product such as Deep Security, Endpoint Sensor, OfficeScan, Worry Free Business Security, or Trend Micro SecurityAffected if Any of these Trend Micro products are installed on the system
-
Check product version against affected listDetermine the exact version number of the installed Trend Micro product using the product's about or version information dialog, or by checking the program files directoryAffected if The installed version matches Deep Security 10.0 or 10.1, Endpoint Sensor 1.6, OfficeScan 11.0 or 12.0, Trend Micro Security 12.0, or Worry Free Business Security 9.5
-
Locate the User-Mode Hooking ModuleSearch for files named umpcm.dll, umph.dll, or similar UMH-related DLL files in the Trend Micro installation directory, typically found under C:\Program Files\Trend Micro or C:\Program Files (x86)\Trend MicroAffected if The UMH module DLL files are present in the Trend Micro installation directory
-
Check DLL search path vulnerabilityExamine the directory permissions and DLL load behavior of the Trend Micro security service that uses the User-Mode Hooking Module. Look for directories where a low-privilege user can write files that could be loaded by the Trend Micro serviceAffected if The Trend Micro service loads DLLs from a directory that allows write access to non-privileged users, enabling DLL hijacking
A system is affected if it has any of the listed Trend Micro products installed with exactly the specified versions and the User-Mode Hooking Module component is present, creating a condition where malicious DLLs could be loaded in place of legitimate ones.
