What is CVE-2020-37137?

The vulnerability in PHP-Fusion 9.03.50 is due to improper handling of POST data in the 'add_panel_form()' function, which leads to remote code execution. Attackers can exploit this flaw by crafting malicious 'panel_content' POST parameters sent to the panels.php administration endpoint, allowing them to execute arbitrary code through the use of an unsanitized eval() function. This represents a significant security risk, as it could enable unauthorized access and control over the affected systems.
