Core FTP Server < 1.2 Build 515 Multiple Vulnerabilities

medium Nessus Plugin ID 72662
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


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.


Upgrade to Core FTP version 1.2 build 515 or later.
