Vulnerability from variot

The Users module in vTiger CRM 4.2 and earlier allows remote attackers to execute arbitrary PHP code via an arbitrary file in the templatename parameter, which is passed to the eval function. vtiger CRM is prone to multiple input validation vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input. vtiger CRM is prone to an SQL injection vulnerability, an arbitrary local file include vulnerability and an arbitrary file upload vulnerability. Several of the issues disclosed by SEC-CONSULT in their referenced security advisory, were previously discussed in BID 15562 (VTiger CRM Multiple Input Validation Vulnerabilities). Users are advised to consult that BID for other vulnerabilities affecting vtiger. Vtiger CRM is a customer relationship management system (CRM) based on SugarCRM developed by American Vtiger Company. The management system provides functions such as management, collection, and analysis of customer information.

TITLE: vtiger CRM Multiple Vulnerabilities

SECUNIA ADVISORY ID: SA17693

VERIFY ADVISORY: http://secunia.com/advisories/17693/

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.

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.
