Short explanation
Metasploit-framework fails to validate IP and port values in FTP PASV responses against the control connection target. According to S0 and S1 records, this allows a rogue FTP server to cause the operator's machine to open a TCP connection to an arbitrary host, resulting in a Server-Side Request Forgery (SSRF) vulnerability.
As stated in S0 records, the vulnerability enables an operator's machine to open TCP connections to arbitrary target systems, triggering risks of unauthorized access to internal network resources.
What should be done?
- Referencing the provided patch references
- Following vendor advisories
Chain of evidence and sources
Metasploit-framework FTP istemcisi, PASV yanıtlarındaki IP ve port değerlerini kontrol bağlantısı hedefiyle doğrulamamaktadır.
Kötü amaçlı bir FTP sunucusu, 227 Pasif Mod yanıtı ile operatörün makinesinin rastgele bir hosta TCP bağlantısı açmasına neden olabilir.
Show the technical text from the sources
The FTP client trusts the server's PASV response IP:port without validation against the control connection target. A rogue FTP server can specify any IP:port in the 227 Passive Mode response, causing the operator's machine to open a TCP connection to an arbitrary host.
