+title: Trusting FTP PASV responses vulnerability in Net::FTP
+date: 2021-07-13
+description: |
+  A malicious FTP server can use the PASV response to trick Net::FTP
+  into connecting back to a given IP address and port. This potentially
+  makes curl extract information about services that are otherwise
+  private and not disclosed (e.g., the attacker can conduct port
+  scans and service banner extractions).
