vulnerabilities that may allow a remote malicious user to compromise the 
affected system.

Details:  
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

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.
