ProFTPD could allow an attacker to obtain valid accounts
| proftpd-info-disclosure (17724) |  Medium Risk |
Description:
ProFTPD could allow a remote attacker to obtain sensitive information using a timing attack. By measuring the amount of time it takes to receive a server response when attempting to authenticate, a remote attacker could obtain valid accounts.
