CVE-2022-44651
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 Time-of-Check Time-Of-Use vulnerability in the Trend Micro Apex One and Apex One as a Service agent could allow a local attacker to escalate privileges on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this 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 confidenceA Time-of-Check Time-of-Use (TOCTOU) vulnerability in the Trend Micro Apex One and Apex One as a Service agent allows a local attacker with the ability to execute low-privileged code to race the privilege check and use window to escalate privileges to a higher account level on the affected system.

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.
-
Verify Apex One agent is installedCheck if the Trend Micro Apex One agent is present on the system by looking for the product in installed programs (Windows Add/Remove Programs) or by querying the system for Apex One processes or services.Affected if The Apex One agent is not installed on the system.
-
Determine installed Apex One versionLocate the installed version of the Apex One agent. This can typically be found in the product's UI (About section), in the Windows registry under the Apex One installation key, or via command-line tools provided by Trend Micro.Affected if The installed version is less than 14.0.11789, or is version 2019 for Apex One as a Service.
-
Confirm agent is runningVerify the Apex One agent service or process is actively running on the system. Check for processes such as 'Apex One' or 'TmListen' in Task Manager or via command line tools.Affected if The Apex One agent service is not running.
-
Verify low-privileged code execution contextAssess whether the system allows low-privileged users to execute code. The vulnerability requires an attacker to have the ability to run low-privileged code to attempt the race condition exploit.Affected if Low-privileged code execution is not possible on the system.
You are affected if the Apex One agent is installed, running, and the version is either below 14.0.11789 or is version 2019 (as a Service), and low-privileged users can execute code on the system.
