"value": "An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. 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)."

Un servidor FTP malicioso puede usar la respuesta PASV para enga\u00f1ar a la funci\u00f3n Net::FTP para que se conecte de nuevo a una direcci\u00f3n IP y un puerto determinados. Esto potencialmente hace que curl extraiga informaci\u00f3n sobre servicios que de otra manera son privados y no son divulgados (por ejemplo, el atacante puede conducir escaneos de puertos y extracciones de banners de servicios)"
