PHPFusion version 9.03.90 is vulnerable to CSRF attack which leads to deletion of all shoutbox messages by the attacker on behalf of the logged in victim.

Due to an out-of-date dependency in the “Fusion File Manager” component accessible through the admin panel, an attacker can send a crafted request that allows them to read the contents of files on the system accessible within the privileges of the running process. Additionally, they may write files to arbitrary locations, provided the files pass the application’s mime-type and file extension validation. 

There is insufficient sanitization of tainted file names that are directly concatenated with a path that is subsequently passed to a ‘require_once’ statement. This allows arbitrary files with the ‘.php’ extension for which the absolute path is known to be included and executed. There are no known means in PHPFusion through which an attacker can upload and target a ‘.php’ file payload.

An issue in Php-Fusion v9.03.90 fixed in v9.10.00 allows authenticated attackers to cause a Distributed Denial of Service via the Polling feature.

PHPFusion 9.03.110 is affected by an arbitrary file upload vulnerability. The File Manager function in admin panel does not filter all PHP extensions such as ".php, .php7, .phtml, .php5, ...". An attacker can upload a malicious file and execute code on the server.
