**Name of the Vulnerable Software and Affected Versions**
MaxCMS version 3.11.20b
**Description**
The issue allows remote attackers to execute arbitrary PHP code via a URL in various parameters, including `is projectPath`, `GLOBALS[thCMS root]`, `is path`, and `thCMS root`, when `register globals` is enabled. This affects multiple files in the includes, classes, and modul directories.
**Recommendations**
For MaxCMS version 3.11.20b, consider disabling the `register globals` setting to prevent exploitation. Additionally, restrict access to the vulnerable parameters, such as `is projectPath`, `GLOBALS[thCMS root]`, `is path`, and `thCMS root`, until a patch is available. Avoid using these parameters in the affected API endpoints, such as `includes/InstantSite/inc.is root.php`, `classes/class.Tree.php`, and `modul/mod.rssreader.php`, until the issue is resolved.
