CVE-2019-18188
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 Apex One could be exploited by an attacker utilizing a command injection vulnerability to extract files from an arbitrary zip file to a specific folder on the Apex One server, which could potentially lead to remote code execution (RCE). The remote process execution is bound to the IUSR account, which has restricted permission and is unable to make major system changes. An attempted attack requires user authentication.
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 confidenceTrend Micro Apex One contains a command injection vulnerability allowing an authenticated attacker to extract files from an arbitrary zip file to specific folders on the server. This could potentially lead to remote code execution, though the IUSR account context limits the impact.

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 Apex One installation and versionCheck the installed version of Trend Micro Apex One. On the server, locate the installation directory (typically C:\Program Files\Trend Micro\Apex One\) and locate a version file, or use the management console to view the product version information.Affected if The installed version is exactly 2019 (any patch level).
-
Confirm web management console is accessibleVerify the Apex One web management console is reachable. Attempt to access the login page via the configured port (default 4343) at https://localhost:4343 or the server's hostname/IP on port 443/4343.Affected if The web management console is accessible over the network without restrictions.
-
Verify authentication is enabled for the consoleCheck that the web console requires authentication by attempting to access protected pages without credentials or reviewing the authentication settings in the Apex One console under Administration > Settings > General Settings.Affected if Anonymous or weak authentication is allowed, or the console is accessible without login credentials.
-
Review user account configurationsExamine the list of configured users who have access to the Apex One management console in the console under Administration > User Accounts > User Account settings.Affected if Unnecessary or weak user accounts exist with management privileges, or default credentials are in use.
The environment is affected if Apex One version 2019 is installed AND the web management console is accessible over the network with authentication controls that may be weak, misconfigured, or use default credentials.
