ZeddYu Lu discovered that the FTP client of Apache Commons Net, a Java client API for basic Internet protocols, trusts the host from PASV response by default. A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client.
