Описание
A flaw was found in the FTP GVfs backend. A malicious FTP server can exploit this vulnerability by providing an arbitrary IP address and port in its passive mode (PASV) response. The client unconditionally trusts this information and attempts to connect to the specified endpoint, allowing the malicious server to probe for open ports accessible from the client's network.
Отчет
This is a LOW impact information disclosure flaw in the GVfs FTP backend. A client connecting to a malicious FTP server could be coerced into probing for open ports accessible from the client's network, as the client unconditionally trusts the IP address and port provided in passive mode (PASV) responses. This vulnerability requires user interaction with a compromised or malicious FTP server.
Меры по смягчению последствий
To mitigate this issue, users should avoid connecting to untrusted or unknown FTP servers when using applications that rely on the GVfs FTP backend. This vulnerability requires the client to interact with a malicious FTP server for exploitation.
