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.
vtiger CRM 7.0.1 is affected by one reflected Cross-Site Scripting (XSS) vulnerability affecting version 7.0.1 and probably prior versions. This vulnerability could allow remote unauthenticated attackers to inject arbitrary web script or HTML via index.php?module=Contacts&view=List (app parameter).
Vtiger CRM 7.1.0 before Hotfix2 allows uploading files with the extension "php3" in the logo upload field, if the uploaded file is in PNG format and has a size of 150x40. One can put PHP code into the image; PHP code can be executed using "<? ?>" tags, as demonstrated by a CompanyDetailsSave action. This bypasses the bad-file-extensions protection mechanism. It is related to actions/CompanyDetailsSave.php, actions/UpdateCompanyLogo.php, and models/CompanyDetails.php.
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.
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.
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.
