New! Plugin Severity Now Using CVSS v3

Synopsis

The FTP server running on the remote host is affected by multiple vulnerabilities.

Description

The version of Core FTP running on the remote host is prior to 1.2 build 515. It is, therefore, affected by multiple vulnerabilities :

- A denial of service vulnerability exists that is triggered when handling malformed data after the 'AUTH SSL' command. An unauthenticated, remote attacker can exploit this to cause an assertion failure, resulting in a server crash. (CVE-2014-1441)

- An information disclosure vulnerability exists due to a failure to properly sanitize user-supplied input. An authenticated, remote attacker can exploit this, via directory traversal using the 'XCRC' command, to gain access to arbitrary files. (CVE-2014-1442)

- An information disclosure vulnerability exists due to improper handling of crafted string data by the 'USER' command. An authenticated, remote attacker can exploit this, via a specially crafted string, to access the password for the user that previously logged on.
(CVE-2014-1443)

Solution

Upgrade to Core FTP version 1.2 build 515 or later.
