CWE	CWE-319: Cleartext Transmission of Sensitive Information
OWASP	A03:2017 - Sensitive Data Exposure
Confidence Level	Low
Impact Level	Low
Likelihood Level	Low

Description

The code is using urllib's URLopener to open FTP URLs, which transmits data unencrypted over the network. This exposes any transmitted credentials or sensitive information to interception.

Impact

Attackers on the network could easily capture usernames, passwords, or files sent via FTP, leading to data leaks or unauthorized access. Using insecure FTP can compromise sensitive data and put user accounts or systems at risk.
