Vulnerability overview/description:
-----------------------------------

NetApp OnCommand System Manager suffers from multiple permanent and reflective 
cross-site scripting vulnerabilities, a local file inclusion vulnerability as 
well as an OS command execution vulnerability.

Malicious, authenticated users can exploit these flaws to change the contents 
of the displayed site, redirect the user to other sites, steal user 
credentials, execute system commands and read sensitive information.

The vendor will not fix the file inclusion and OS command execution issues,
as it is considered a design feature. 



Proof of concepts:
-----------------

1) Multiple Reflective Cross-Site Scripting Vulnerabilities (internal bug 
number 654355) - CVE-2013-3320

When configuring CIFS (Configuration > Protocols > CIFS > Configuration > 
Setup), JavaScript can be inserted into the parameters <domain-name> and 
<value>.

Request (domain-name):
    POST /zapiServlet HTTP/1.1
    Host: 127.0.0.1:1195

    [...]

    <netapp version="1.7" 
xmlns="http://www.netapp.com/filer/admin";><cifs-setup><auth-type>workgroup</auth-type><domain-name><img src=x 
onerror=alert(1) 
</domain-name><security-style>multiprotocol</security-style><server-name>FILER</server-name></cifs-setup></netapp>


Furthermore, when creating new LUNs or editing already existing ones (Storage > LUNs >
(Create or Edit)), JavaScript can be inserted into the parameter <comment>.


2) Multiple permanent cross-site scripting vulnerabilities (internal bug 
number 654355) - CVE-2013-3320

When creating new users or editing already existing ones (Configuration > 
Local Users and Groups > Users > (Create or Edit)), JavaScript can be inserted 
into the parameters <full-name> and <comment>.

Request (full-name):
    POST /zapiServlet HTTP/1.1
    Host: 127.0.0.1:1457

    [...]

    <netapp version="1.7" 
xmlns="http://www.netapp.com/filer/admin";><useradmin-user-modify><useradmin-user><useradmin-user-info><full-name>test<img
 src=x onerror=alert(1) 
</full-name><comment>test</comment><name>test</name><password-maximum-age>4294967295</password-maximum-age><password-minimum-age>0</password-minimum-age><useradmin-groups><useradmin-group-info><name>Administrators</name></useradmin-group-info></useradmin-groups></useradmin-user-info></useradmin-user></useradmin-user-modify></netapp>


Furthermore, when creating new groups or editing already existing ones (Configuration > 
Local Users and Groups > Groups > (Create or Edit)), JavaScript can be 
inserted into the parameter <comment>.


When creating new shares or editing already existing ones (Storage > Shares >
(Create or Edit)), JavaScript can be inserted into the parameter <comment>.


3) Local File Inclusion (internal bug number 654357) - CVE-2013-3321 *
When retrieving log files through SnapMirror (Diagnostics > SnapMirror Log), 
the path can be changed to read arbitrary files from the file system.


4) OS Command Execution (internal bug number 654360) - CVE-2013-3322 *

When using the Halt/Reboot interface (Configuration > System Tools > Halt/Reboot), 
arbitrary OS commands can be injected.


* To exploit these issues, the attacker must be authenticated as root. The 
vendor will not fix these issues, as it is considered a design feature. Hence 
no proof of concept will be included within this advisory.
