DESCRIPTION:
Some vulnerabilities have been discovered in vtiger CRM, which can be
exploited by malicious users to compromise a vulnerable system and by
malicious people to conduct cross-site scripting attacks and disclose
sensitive information.

1) An error exists in the file upload functionality due to the emails
module not properly checking file names and extensions. This can be
exploited to upload and execute arbitrary PHP code e.g. via ".phtml"
files.

2) Input passed e.g. via the "lang_crm" parameter to phprint.php or
the "current_language" parameter to graph.php is not properly
verified in the "return_application_language()" function in
include/utils/utils.php before being used to include files. This can
be exploited to include arbitrary file from local resources via
directory traversal sequences and URL-encoded NULL bytes.

Successful exploitation of this vulnerability requires that
"magic_quotes_gpc" is disabled.

3) Input passed via the "user_name" and "user_password" parameters to
index.php is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

4) Input passed via the "label" parameter to index.php (when "module"
is set to "Settings" and "action" is set to "GetFieldInfo") is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

The vulnerabilities are confirmed in version 5.2.0. Other versions
may also be affected.

SOLUTION:
Update to version 5.2.1.
