CyberRota Analysis

AI-Generated

Pluck CMS versions up to 4.7.21 are vulnerable due to an inadequate file upload restriction mechanism that fails to account for the '.php8' extension, allowing authenticated administrators to upload malicious files like shell.php8. This oversight can lead to remote code execution on servers running PHP 8.x, posing a significant security risk. Organizations using Pluck CMS should prioritize addressing this vulnerability to prevent potential exploitation.

Original NVD Description

Pluck CMS through 4.7.21 restricts dangerous file uploads in its admin file-management feature using a fixed blacklist in data/inc/files.php ('.php','php3','php4','php5','php6','php7','phtml','.phtm','.pht','.ph3','.ph4','.ph5','.asp','.cgi','.phar'), checked against the last 4-5 characters of the filename.
