Trend Micro Password Manager
Trend Micro Password Manager is a standalone software which is also deployed along with the Trend Micro Maximum Security product. The purpose of the software is to manage website passwords and login IDs in one secure location.

Part of the software runs as a Windows service executed as “NT AUTHORITY\SYSTEM,” which provides it with very powerful permissions.

In this post, we describe the vulnerability we found in the Trend Micro Password Manager.

We then demonstrate how this vulnerability can be exploited to achieve privilege escalation, gaining access with NT AUTHORITY\SYSTEM level privileges.
