DESCRIPTION:
High-Tech Bridge SA has discovered some vulnerabilities in vtiger
CRM, which can be exploited by malicious users to compromise a
vulnerable system.

1) Input passed to the "file" parameter in index.php is not properly
verified before being used to include files. This can be exploited to
include arbitrary files within the vtiger CRM deployment path and
execute arbitrary PHP code by e.g. including a previously uploaded
file with ".txt" extension containing PHP code via directory
traversal sequences and URL-encoded NULL bytes.

2) Input passed to the "module" and "action" parameters in graph.php
is not properly verified before being used to include files. This can
be exploited to include arbitrary files within the vtiger CRM
deployment path and execute arbitrary PHP code by e.g. including a
previously uploaded file with ".txt" extension containing PHP code
via directory traversal sequences and URL-encoded NULL bytes.

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

The vulnerabilities are confirmed in version 5.2.1. Other versions
may also be affected.

SOLUTION:
Update to version 5.3.0 RC.
