A Server-Side Request Forgery (SSRF) vulnerability, achievable through an XML External Entity (XXE) injection, exists in MetInfo Content Management System (CMS) thru 8.1. This flaw stems from a defect in the XML parsing logic, which allows an attacker to construct a malicious XML entity that forces the server to initiate an HTTP request to an arbitrary internal or external network address. Successful exploitation could lead to internal network reconnaissance, port scanning, or the retrieval of sensitive information. The vulnerability may be present in the backend API called by or associated with the path `/admin/#/webset/?head_tab_active=0`, where user-provided XML data is processed.
Cross-site scripting (XSS) vulnerability in search/search.php in MetInfo 3.0 allows remote attackers to inject arbitrary web script or HTML via the searchword parameter (aka Search Box field). NOTE: some of these details are obtained from third party information.
