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.
An issue was discovered in Metinfo 6.x. An attacker can leverage a race condition in the backend database backup function to execute arbitrary PHP code via admin/index.php?n=databack&c=index&a=dogetsql&tables=<?php and admin/databack/bakup_tables.php?2=file_put_contents URIs because app/system/databack/admin/index.class.php creates bakup_tables.php temporarily.
MetInfo 6.0.0 allows a CSRF attack to add a user account via a doaddsave action to admin/index.php, as demonstrated by an admin/index.php?anyid=47&n=admin&c=admin_admin&a=doaddsave URI.
Metinfo v6.0.0 allows remote attackers to write code into a .php file, and execute that code, via the module parameter to admin/column/save.php in an editor upload action.
An issue was discovered in MetInfo 6.0.0. admin/app/batch/csvup.php allows remote attackers to delete arbitrary files via a flienamecsv=../ directory traversal. This can be exploited via CSRF.
An issue was discovered in MetInfo 6.0.0. install\index.php allows remote attackers to write arbitrary PHP code into config_db.php, a different vulnerability than CVE-2018-7271.
