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 confidenceA privilege escalation vulnerability in Trend Micro HouseCall for Home Networks (versions below 5.3.0.1063) allows local attackers to place a malicious DLL file in the application directory. When the application runs with elevated privileges, it loads the attacker-controlled DLL, resulting in privilege escalation.

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 Trend Micro HouseCall for Home Networks is installedCheck the default installation path (C:\Program Files\Trend Micro\HouseCall for Home Networks) or search for the application in Windows Programs and FeaturesAffected if The application is found on the system
-
Determine the installed versionRight-click the HouseCall executable, select Properties, and view the Details tab for the Product Version, or query the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{GUID}Affected if The version is below 5.3.0.1063
-
Verify the application runs with elevated privilegesObserve the application behavior during startup or check if User Account Control (UAC) prompts appear when launching HouseCall, or review the application manifest for requestedExecutionLevelAffected if The application runs with administrator or elevated privileges
-
Inspect the application directory for unauthorized DLL filesList all .dll files in the HouseCall installation directory (C:\Program Files\Trend Micro\HouseCall for Home Networks\) and compare against known legitimate DLLs shipped with the productAffected if Unexpected or suspicious DLL files exist in the application directory that were not part of a legitimate installation
The system is affected if Trend Micro HouseCall for Home Networks version below 5.3.0.1063 is installed and runs with elevated privileges, allowing potential DLL hijacking.
