Description
This security bulletin contains information about 1 security vulnerability.
1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-4189)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in the FTP (File Transfer Protocol) client library when using it in PASV (passive) mode. A remote attacker can set up a malicious FTP server, trick the FTP client in Python into connecting back to a given IP address and port, which can lead to FTP client scanning ports which otherwise would not have been possible.
