Reflected XSS in Vtiger CRM v7.2.0 in vtigercrm/index.php? through the view parameter can result in an attacker performing malicious actions to users who open a maliciously crafted link or third-party web page.
Unrestricted file upload vulnerability in the Settings_Vtiger_CompanyDetailsSave_Action class in modules/Settings/Vtiger/actions/CompanyDetailsSave.php in Vtiger CRM 6.3.0 and earlier allows remote authenticated users to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in test/logo/.
vtiger CRM 5.4.0 and earlier contain local file-include vulnerabilities in 'customerportal.php' which allows remote attackers to view files and execute local script code.
In Vtiger 7.x before 7.2.0, the My Preferences saving functionality allows a user without administrative privileges to change his own role by adding roleid=H2 to a POST request.
