Metinfo 5.3.18 is affected by: Cross Site Request Forgery (CSRF). The impact is: Information Disclosure (remote). The component is: admin/index.php. The attack vector is: The administrator clicks on the malicious link in the login state.
Multiple cross-site scripting (XSS) vulnerabilities in admin/index.php in Metinfo 5.3.18 allows remote attackers to inject arbitrary web script or HTML via the (1) class1 parameter or the (2) anyid parameter.
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.
In Metinfo 6.1.3, include/interface/applogin.php allows setting arbitrary HTTP headers (including the Cookie header), and common.inc.php allows registering variables from the $_COOKIE value. This issue can, for example, be exploited in conjunction with CVE-2018-19835 to bypass many XSS filters such as the Chrome XSS filter.
