CVE-2020-15604
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 incomplete SSL server certification validation vulnerability in the Trend Micro Security 2019 (v15) consumer family of products could allow an attacker to combine this vulnerability with another attack to trick an affected client into downloading a malicious update instead of the expected one. CWE-494: Update files are not properly verified.
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 confidenceTrend Micro Security 2019 (v15) consumer products have incomplete SSL server certificate validation during the update process, allowing man-in-the-middle attackers to intercept update connections and deliver malicious updates instead of legitimate ones. This is a CWE-494 (download of code without integrity check) vulnerability requiring chaining with another attack vector.

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 productOpen Programs and Features or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' to list installed software and look for Trend Micro Security 2019 productsAffected if Any of these are present: Trendmicro Antivirus+ 2019, Trendmicro Internet Security 2019, Trendmicro Maximum Security 2019, Trendmicro Officescan Cloud, or Trendmicro Premium Security 2019
-
Check installed version numberLocate the Trend Micro product in Programs and Features and note the version column, or check the product's About/Support information within the software interfaceAffected if Version is 15.0 or lower (or version 15 for Officescan Cloud)
-
Confirm update functionality is enabledOpen the Trend Micro main console, go to Settings or Preferences, and verify that Automatic Updates or Live Update is turned on (this is the default state)Affected if Updates are enabled - the vulnerability only applies when the product attempts to download updates from Trend Micro servers
-
Verify product is active and not migratedConfirm the installed product has not been upgraded to a newer version or replaced with a supported Trend Micro security product (such as Trend Micro Security 2020 or later)Affected if The product remains at the v15 (2019) release and is actively installed
You are affected if a Trend Micro Security 2019 consumer product (Antivirus+, Internet Security, Maximum Security, or Premium Security) or Officescan Cloud version 15 is installed at version 15.0 or lower, with update functionality enabled.

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 dataUpdate to the latest version of Trend Micro Security 2019 or migrate to a supported product version that includes proper SSL certificate validation and update file integrity verification.
