Introduction:
=============
Dell KACE is to provide an appliance-based approach to systems management, to create time for systems administration professionals, 
while saving money for their companies. Dell KACE Systems Management Appliances are available as both physical and virtual appliances. 

The KACE Management Appliance delivers a fully integrated systems management solution, unlike traditional software approaches that 
can require complex and time-consuming deployment and maintenance. KACE accomplishes this via an extremely flexible, intelligent 
appliance-based architecture that typically deploys in days and is self maintaining. The KACE Management Appliance also provides 
direct access to time-saving ITNinja systems management community information using AppDeploy Live, the leading destination for end 
point administrators. The result: Comprehensive systems management that is easy-to-use and that can be more economical than software 
only alternatives. Read more in the white paper KACE K1000 Management Appliance Architecture: Harnessing the Power of an 
Appliance-based Architecture. The KACE Management Appliance is designed for enterprises and business units with up to 20,000 nodes.

Severity:

Medium


Details:
========
Multiple persistent input validation web vulnerabilities are detected in Dell Kace K1000, Systems Management Appliance.
The vulnerabilityallows an attacker to inject own malicious script code in the vulnerable module on application side (persistent).

The first vulnerability is located in the `Inventory` module with the bound vulnerable Ip-address, Mac, Os Name, Service pack, 
Notes and Label Name parameters. The persistent injected script code will be executed directly out of the `Computer` listing 
when processing to manage the earlier inserted machines in dbms context.

The second vulnerability is located in the `Distribution` module with the bound vulnerable Machine Name and Mac address parameters. 
The persistent injected script code will be executed directly out of the `Walk-on-lan` exception handling mechanism when a malicious 
data is inserted in the vulnerable fields.

Successful exploitation of the vulnerabilities result in persistent session hijacking, persistent phishing, persistent external 
redirects, persistent external malware loads via inject and persistent vulnerable module web context manipulation.

Vulnerable Section(s):
      [+] Inventory => Computers
      [+] Inventory => Computers
      [+] Distribution =>  Wake-on-lan

Vulnerable Module(s):
      [+] Add New Item
      [+] Add Label
      [+] Add new Item
 
Vulnerable Parameter(s):
      [+] [Ip-address] [Mac] [Os Name] [Service pack] [Notes]
      [+] [Label Name]
      [+] [Machine Name] [Mac address]

Affected Modules(s):
      [+] Inventory => Computers
      [+] Inventory => Computers => Choose Action Menu => Apply label
      [+] Distribution =>  Wake-on-lan =>Exception handeling 


Proof of Concept:
=================
The vulnerability can be exploited by remote attackers with low user interaction and low privilege application user account.

<b><u>Wake-on-LAN</u></b>
<br/><br/>
This page allows you to wake up a computer or other device that has been inventoried by the K1000 
if the remote device is attached to the network and supports Wake-on-LAN.  If the device you wish to wake is not inventoried by the K1000 
but you still know the MAC (Hardware) address and its last-known IP address, you can manually enter the info to wake the device.
