What is CVE-2020-8634?

Wing FTP Server v6.2.3 poses a security risk due to inadequate file permissions granted to files modified through the HTTP file management interface. This flaw allows files to be unintentionally saved with permissions that make them world-readable and world-writable. If a sensitive file is edited in this manner, a low-privilege user could exploit this vulnerability to escalate their privileges to that of the root user, potentially leading to unauthorized access and control over critical system files.
