DESCRIPTION:
Some vulnerabilities have been reported in Trend Micro InterScan Web
Security Virtual Appliance, which can be exploited by malicious users
to disclose potentially sensitive information or compromise a
vulnerable system, and by malicious people to conduct cross-site
request forgery attacks.

1) The web-based user interface allows user to perform certain
actions via HTTP requests without performing any validity checks to
verify the requests. This can be exploited to e.g. add a web site to
the URL blocking list or add new users when a logged-in
administrative user visits a specially crafted web site.

2) Input passed via the "exportname" parameter to
/servlet/com.trend.iwss.gui.servlet.exportreport is not properly
sanitised before being used. This can be exploited to download
arbitrary files from the system via directory traversal attacks.

3) Input passed via the "pkg_name" parameter to
/servlet/com.trend.iwss.gui.servlet.ConfigBackup is not properly
sanitised before being used to download files, which can be exploited
to download arbitrary files from the system.

Successful exploitation of vulnerabilities #2 and #3 requires
authentication and administrative or reporter privileges.

4) Input passed via the "filename" parameter to
/servlet/com.trend.iwss.gui.servlet.XMLRPCcert is not properly
sanitised before being used. This can be exploited to upload
arbitrary files to arbitrary locations via directory traversal
attacks.

Successful exploitation of this vulnerability requires
authentication.

SOLUTION:
Apply Critical Patch Build 1386.
