29
FAUCET Score

CVE-2020-37137 is a critical remote code execution vulnerability affecting PHP-Fusion 9.03.50. It allows unauthenticated attackers to execute arbitrary code by sending crafted POST data to the panels.php administration endpoint, which is then unsafely processed by an eval() function within 'add_panel_form()'. With a CVSS score of 9.8 (Critical), this vulnerability poses a significant risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, public exploit code (e.g., Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
