TITLE

VTiger CRM Multiple Input Validation Vulnerabilities

DESCRIPTION

Multiple directory traversal vulnerabilities in index.php in vTiger CRM 4.2 and earlier allow remote attackers to read or include arbitrary files, an ultimately execute arbitrary PHP code, via .. (dot dot) and null byte ("%00") sequences in the (1) module parameter and (2) action parameter in the Leads module, as also demonstrated by injecting PHP code into log messages and accessing the log file. 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 multiple SQL injection, HTML injection, cross-site scripting and local file include vulnerabilities. An attacker can exploit these issues to gain administrative access, retrieve username and password pairs, steal cookie-based authentication credentials and retrieve arbitrary local files in the context of the Web server process; other attacks are also possible. Some of these issues may be related to those discussed in BID 11740 (SugarCRM Multiple Input Validation Vulnerabilities) discovered by James Bercegay and Damon Wood of the GulfTech Security Research Team, as vtiger is a fork of the SugarCRM project. An independent study by Daniel Fabian of SEC-CONSULT has confirmed the existence of several of these issues. Please see the referenced advisory for more information. 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.
