Vulnerability from variot
vtiger CRM 4.2.4, and possibly earlier, allows remote attackers to bypass authentication and access administrative modules via a direct request to index.php with a modified module parameter, as demonstrated using the Settings module. The vtiger CRM is prone to HTML-injection and access-control-bypass vulnerabilities because the application fails to properly sanitize user-supplied input and effectively control access to administrative modules. Version 4.2.4 of vtiger CRM is reportedly affected; previous versions may be vulnerable as well.

TITLE: vtiger CRM Script Insertion and Administrative Modules Access
SECUNIA ADVISORY ID: SA21728
VERIFY ADVISORY: http://secunia.com/advisories/21728/
CRITICAL: Moderately critical
IMPACT: Security Bypass, Cross Site Scripting
WHERE:
From remote
SOFTWARE: vtiger CRM 4.x http://secunia.com/product/6211/
DESCRIPTION: Ivan Markovic has discovered some vulnerabilities in vtiger CRM, which can be exploited by malicious people to conduct script insertion attacks and bypass certain security restrictions.
1) Input passed to the "description" field in various modules when e.g. creating a contact and the "solution" field when an administrator modifies the solution in the HelpDesk modules isn't properly sanitised before being used. This 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 the malicious user data is viewed.
2) An error in the access control verification can be exploited by a normal user to access administrative modules (e.g. the settings section) by accessing certain URLs directly.
The vulnerabilities have been confirmed in version 4.2.4.
