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.
login.php in PHPFusion (aka PHP-Fusion) Andromeda 9.x before 2020-12-30 generates error messages that distinguish between incorrect username and incorrect password (i.e., not a single "Incorrect username or password" message in both cases), which might allow enumeration.
Privilege escalation in PHP-Fusion 9.03.50 downloads/downloads.php allows an authenticated user (not admin) to send a crafted request to the server and perform remote command execution (RCE).
In administration/comments.php in PHP-Fusion 9.03.50, an authenticated attacker can take advantage of a stored XSS vulnerability in the Preview Comment feature. The protection mechanism can be bypassed by using HTML event handlers such as ontoggle.
Multiple Cross-site scripting vulnerabilities in PHP-Fusion 9.03.50 allow remote attackers to inject arbitrary web script or HTML via the go parameter to faq/faq_admin.php or shoutbox_panel/shoutbox_admin.php
