X2CRM v8.5 is vulnerable to a stored Cross-Site Scripting (XSS) in the "Opportunities" module. An attacker can inject malicious JavaScript code into the "Name" field when creating a list.

A Cross-Site Scripting (XSS) attack can cause arbitrary code (javascript) to run in a user’s browser while the browser is connected to a trusted website. As the vehicle for the attack, the application targets the users and not the application itself. Additionally, the XSS payload is executed when the user attempts to access any page of the CRM.

Cross Site Scripting (XSS) in X2Engine X2CRM v6.9 and older allows remote attackers to execute arbitrary code by injecting arbitrary web script or HTML via the "New Name" field of the "Rename a Module" tool.

Cross Site Scripting (XSS) in X2engine X2CRM v7.1 and older allows remote attackers to obtain sensitive information by injecting arbitrary web script or HTML via the "First Name" and "Last Name" fields in "/index.php/contacts/create page"

Cross Site Scripting (XSS) in X2Engine X2CRM v7.1 allows remote attackers to obtain sensitive information by injecting arbitrary web script or HTML via the "Comment" field in "/profile/activity" page.

Unrestricted file upload vulnerability in the ProfileController::actionUploadPhoto method in protected/controllers/ProfileController.php in X2Engine X2CRM before 4.0 allows remote attackers to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in an unspecified directory.

Multiple cross-site scripting (XSS) vulnerabilities in X2Engine X2CRM before 5.0.9 allow remote attackers to inject arbitrary web script or HTML via the (1) version parameter in protected/views/admin/formEditor.php; the (2) importId parameter in protected/views/admin/rollbackImport.php; the (3) bc, (4) fg, (5) bgc, or (6) font parameter in protected/views/site/listener.php; the (7) Services[*] parameter in protected/components/views/webForm.php; the (8) file parameter in protected/components/TranslationManager.php; the (9) x2_key parameter in protected/tests/webscripts/x2WebTrackingTestPages/customWebLeadCaptureScriptTest.php; the (10) id parameter in protected/modules/contacts/controllers/ContactsController.php; or the (11) lastEventId parameter to index.php/profile/getEvents.

Incomplete blacklist vulnerability in the FileUploadsFilter class in protected/components/filters/FileUploadsFilter.php in X2Engine X2CRM before 5.0.9 allows remote authenticated users to execute arbitrary PHP code by uploading a file with a .pht extension.

Cross-site request forgery (CSRF) vulnerability in X2Engine X2CRM before 5.2 allows remote attackers to hijack the authentication of administrators for requests that create an administrative account via a crafted request to index.php/users/create.

FileUploadsFilter.php in X2Engine 4.1.7 and earlier, when running on case-insensitive file systems, allows remote attackers to bypass the upload blacklist and conduct unrestricted file upload attacks by uploading a file with an executable extension that contains uppercase letters, as demonstrated using a PHP program.
