CVE-2018-15363
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 Out-of-Bounds Read Privilege Escalation vulnerability in Trend Micro Security 2018 (Consumer) products could allow a local attacker to escalate privileges on vulnerable installations. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit the vulnerability.
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 confidenceAn out-of-bounds read vulnerability in Trend Micro Security 2018 (Consumer) allows a local attacker with low-privileged code execution to read sensitive memory contents and escalate to elevated (administrator/system) privileges. The flaw exists in a component of the security product that processes certain operations without proper bounds checking.

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 Security productOpen Control Panel > Programs and Features, or check Program Files for Trend Micro folders (usually in C:\Program Files\Trend Micro or C:\Program Files (x86)\Trend Micro). Look for product name like 'Trend Micro Security', 'Trendmicro Antivirus + Security', 'Trendmicro Internet Security', 'Trendmicro Maximum Security', or 'Trendmicro Premium Security'.Affected if Any of these Trend Micro consumer security products are found installed on the system.
-
Check installed product versionRight-click the installed Trend Micro program in Programs and Features and select 'Properties', or look for version information in the program's main UI under 'About' or 'Help > About'. Compare the version number to the affected range (12.0 or lower).Affected if The installed version is 12.0 or any version lower than 12.0.
-
Confirm specific product variantIdentify whether the installed product is one of: Antivirus + Security, Internet Security, Maximum Security, or Premium Security (all version 12.0 and below). Check the product name displayed in the UI or program folder name.Affected if The product is any of these four consumer products at version 12.0 or below.
-
Verify vulnerability is exploitableThis vulnerability requires the security product to be actively running and processing operations. Check if the Trend Micro real-time protection service (usually 'Trend Micro Security Agent' or 'TMCCSF' service) is running. The flaw is in a component that processes certain operations without proper bounds checking.Affected if The Trend Micro security product is running with real-time protection enabled, and the version is within the affected range.
A user is affected if they have any of these Trend Micro consumer products installed (Antivirus + Security, Internet Security, Maximum Security, or Premium Security) at version 12.0 or lower with the security software actively running.
