Name of the Vulnerable Software and Affected Versions NoneCms version 1.3

Description An issue in thinkphp/library/think/App.php allows remote attackers to execute arbitrary PHP code via crafted use of the filter parameter. This is demonstrated by the query string "s=index/thinkRequest/input&filter=phpinfo&data=1". The filter parameter is used to manipulate the execution of PHP code, allowing attackers to execute arbitrary code.

Recommendations NoneCms version 1.3: Update the thinkphp/library/think/App.php file to prevent the manipulation of the filter parameter, ensuring that only authorized input is accepted to prevent remote code execution.
