Vtiger CRM v7.4.0 was discovered to contain a stored cross-site scripting (XSS) vulnerability via the e-mail template modules.

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 an Authentication Bypass Vulnerability due to improper authentication validation in the validateSession function.

vtiger CRM 5.4.0 and earlier contain a PHP Code Injection Vulnerability in 'vtigerolservice.php'.

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.

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).

SQL injection vulnerability in Vtiger CRM before 7.1.0 hotfix3 allows authenticated users to execute arbitrary SQL commands.

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.

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.

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.

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.

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.
