CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, Manipulation of data, Exposure
of sensitive information, System access

WHERE:
>From remote

SOFTWARE:
vtiger CRM 4.x
http://secunia.com/product/6211/

DESCRIPTION:
Christopher Kunz has reported some vulnerabilities in vtiger CRM,
which can be exploited by malicious people to conduct cross-site
scripting, script insertion, and SQL injection attacks, disclose
sensitive information, and compromise a vulnerable system.

1) Some input isn't 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.

2) An input validation error in the RSS aggregation module can be
exploited to inject arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
when data from the malicious RSS feed is viewed.

3) Input passed to the "date" parameter and the username field when
logging into the administration section isn't properly sanitised
before being used in a SQL query. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.

This can further be exploited to bypass the authentication process
and access the administration section where sensitive user data can
be disclosed or manipulated.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

4) Input passed to the "action" and "module" parameters isn't
properly verified, before it is used to include files. This can be
exploited to include arbitrary files from local resources.

This can further be exploited to include and execute arbitrary PHP
code injected into the "vtigercrm.log" log file.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerabilities have been reported in version 4.2 and prior.
Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified.
