VTiger CRM <= 8.1.0 does not properly sanitize user input before using it in a SQL statement, leading to a SQL Injection in the "CompanyDetails" operation of the "MailManager" module.
VTiger CRM <= 8.1.0 does not correctly check user privileges. A low-privileged user can interact directly with the "Migration" administrative module to disable arbitrary modules.
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.
Incomplete blacklist vulnerability in config.template.php in vtiger CRM before 5.2.1 allows remote authenticated users to execute arbitrary code by using the draft save feature in the Compose Mail component to upload a file with a .phtml extension, and then accessing this file via a direct request to the file in the storage/ directory tree.
