EMC CTA is vulnerable to XML External Entity (XXE) and information disclosure vulnerabilities that may allow a remote malicious user to compromise the affected system.

EMC CTA versions 10 and 10 SP1 are vulnerable to XXE attack (CVE-2014-0644) which may allow a remote unauthenticated user to access arbitrary files on the affected system with root privileges. The exploit code that exposes the password file has been made available to the public. This vulnerability does not affect CTA 9.x and FMA 7.x versions.

CVSS 8.5 (AV:N/AC:L/Au:N/C:C/I:N/A:P)

In addition, the default passwords for built-in accounts (root, super, admin) are stored using a weak DES-based hash (CVE-2014-0645).  This issue does not affect passwords changed during installation/usage of the product and/or for newly added accounts. This issue affects all versions of CTA and FMA.    

CVSS 6.6 (AV:L/AC:M/Au:S/C:C/I:C/A:C)

The below product version contain resolution to both these issues:
 CTA 10.0 SP1.1
EMC strongly recommends all CTA 10.0 and 10.0 SP1 customers upgrade to 10.0 SP1.1 at the earliest opportunity.

EMC strongly recommends all CTA and FMA customers change the default password for all users namely SSH users "root" and "super" as well as GUI "admin" accounts.  See CTA Getting Started Guide for information on how to change passwords.
