Unrestricted file upload vulnerability in the Settings_Vtiger_CompanyDetailsSave_Action class in modules/Settings/Vtiger/actions/CompanyDetailsSave.php in Vtiger CRM 6.4.0 allows remote authenticated users to execute arbitrary code by uploading a crafted image file with an executable extension, then accessing it via a direct request to the file in test/logo/. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-6000.

modules/Users/actions/Save.php in Vtiger CRM 6.4.0 and earlier does not properly restrict user-save actions, which allows remote authenticated users to create or modify user accounts via unspecified vectors.

Directory traversal vulnerability in kcfinder/browse.php in Vtiger CRM before 6.0.0 Security patch 1 allows remote authenticated users to read arbitrary files via a .. (dot dot) in the file parameter in a download action. NOTE: it is likely that this issue is actually in the KCFinder third-party component, and it affects additional products besides Vtiger CRM.

views/Index.php in the Install module in vTiger 6.0 before Security Patch 2 does not properly restrict access, which allows remote attackers to re-install the application via a request that sets the X-Requested-With HTTP header, as demonstrated by executing arbitrary PHP code via the db_name parameter.

modules/Users/ForgotPassword.php in vTiger 6.0 before Security Patch 2 allows remote attackers to reset the password for arbitrary users via a request containing the username, password, and confirmPassword parameters.

Multiple SQL injection vulnerabilities in vTiger CRM 5.0.0 through 5.4.0 allow remote attackers to execute arbitrary SQL commands via the (1) picklist_name parameter in the get_picklists method to soap/customerportal.php, (2) where parameter in the get_tickets_list method to soap/customerportal.php, or (3) emailaddress parameter in the SearchContactsByEmail method to soap/vtigerolservice.php; or remote authenticated users to execute arbitrary SQL commands via the (4) emailaddress parameter in the SearchContactsByEmail method to soap/thunderbirdplugin.php.

Cross-site scripting (XSS) vulnerability in vTiger CRM 5.4.0 allows remote attackers to inject arbitrary web script or HTML via the (1) return_url parameter to modules\com_vtiger_workflow\savetemplate.php, or unspecified vectors to (2) deletetask.php, (3) edittask.php, (4) savetask.php, or (5) saveworkflow.php.

SQL injection vulnerability in CalendarCommon.php in vTiger CRM 5.4.0 and possibly earlier allows remote authenticated users to execute arbitrary SQL commands via the onlyforuser parameter in an index action to index.php. NOTE: this issue might be a duplicate of CVE-2011-4559.

Directory traversal vulnerability in modules/com_vtiger_workflow/sortfieldsjson.php in vtiger CRM 5.1.0 allows remote attackers to read arbitrary files via a .. (dot dot) in the module_name parameter.

Multiple cross-site scripting (XSS) vulnerabilities in the customer portal in vtiger CRM before 5.2.0 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.
