FTP Service AUTH TLS Plaintext Command Injection

medium Nessus Plugin ID 53847

Language:

Synopsis

The remote FTP server allows plaintext command injection while negotiating an encrypted communications channel.

Description

The remote FTP server contains a software flaw in its AUTH TLS implementation that could allow a remote, unauthenticated attacker to inject commands during the plaintext protocol phase that will be executed during the ciphertext protocol phase.

Successful exploitation could permit an attacker to modify files on the FTP server and reveal a user's credentials.

Solution

Contact the vendor to see if an update is available.
