Sitemagic CMS v4.4 has XSS in SMFiles/FrmUpload.class.php via the filename parameter.

Sitemagic CMS 4.4.1 is affected by a Cross-Site-Scripting (XSS) vulnerability, as it fails to validate user input. The affected components (index.php, upgrade.php) allow for JavaScript injection within both GET or POST requests, via a crafted URL or via the UpgradeMode POST parameter.

Sitemagic CMS 4.4.1 is affected by a Cross-Site-Request-Forgery (CSRF) issue as it doesn't implement any method to validate incoming requests, allowing the execution of critical functionalities via spoofed requests. This behavior could be abused by a remote unauthenticated attacker to trick Sitemagic users into performing unwarranted actions.

An issue was discovered in Sitemagic CMS v4.4. In the index.php?SMExt=SMFiles URI, the user can upload a .php file to execute arbitrary code, as demonstrated by 404.php. This can only occur if the administrator neglects to set FileExtensionFilter and there are untrusted user accounts. NOTE: The maintainer states that this is not a vulnerability but a feature used in conjunction with External Modules

SitemagicCMS 4.4.3 contains a remote code execution vulnerability that allows attackers to upload malicious PHP files to the files/images directory. Attackers can upload a .phar file with system command execution payload to compromise the web application and execute arbitrary system commands.
