Title: VTiger CRM HTML Injection and Access Control Bypass Vulnerabilities
Severity: HIGH
Description:
The vtiger application is an open-source customer relationship management (CRM) system implemented in PHP.
The application is prone to HTML-injection and access-control-bypass issues because it fails to properly sanitize user-supplied input and effectively control access to administrative modules.
HTML-injection vulnerability
This issue occurs because the application fails to properly sanitize user-supplied input to the 'description' field in numerous unspecified modules.
Generally, attacker-supplied HTML and script code would execute in the context of the affected website, potentially allowing an attacker to steal cookie-based authentication credentials and to control how the site is rendered to the user; other attacks are also possible.
Access-control-bypass vulnerability
Reportedly, vtiger does not effectively control access to administrative modules when their URL is requested directly. This allows a normal non-privileged user to access and use administrative modules that normally require authentication and administrative privileges.
Version 4.2.4 of vtiger CRM is reportedly affected; previous versions may be vulnerable as well.
Affected Products:
- vtiger vtiger CRM 4.2.4
