v11.0 and XG (12.0)*

OfficeScan protects enterprise networks from malware, network viruses, web-based threats, spyware, and mixed threat attacks.
An integrated solution, OfficeScan consists of the OfficeScan agent program that resides at the endpoint and a server program that
manages all agents. The OfficeScan agent guards the endpoint and reports its security status to the server. The server, through the
web-based management console, makes it easy to set coordinated security policies and deploy updates to every agent.

Vulnerability Type:
Unauthorized Encryption Key Disclosure

CVE Reference:

Security Issue:
Remote unauthenticated attackers who can reach the TrendMicro OfficeScan XG application which usually runs on port 4343 can download
the OfficeScan XG encryption "crypt.key" file. This crypt.key is used for the OfficeScan XG encryption process.
