Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
A command injection vulnerability in FTP-Flask-python through 5173b68 allows unauthenticated remote attackers to execute arbitrary OS commands. The /ftp.html endpoint's "Upload File" action constructs a shell command from the ftp_file parameter and executes it using os.system() without sanitization or escaping.
