Adobe ColdFusion Multiple Flaws Let Remote Users Execute Arbitrary Code and Conduct Cross-Site Scripting and XML External Entity Attacks
SecurityTracker Alert ID:  1039321
SecurityTracker URL:  http://securitytracker.com/id/1039321
CVE Reference:   CVE-2017-11283, CVE-2017-11284, CVE-2017-11285, CVE-2017-11286   (Links to External Site)
Date:  Sep 12 2017
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Several vulnerabilities were reported in Adobe ColdFusion. A remote user can execute arbitrary code on the target system. A remote user can conduct cross-site scripting attacks. A remote user can conduct XML external entity attacks to obtain files on the target system.

A remote user can send specially crafted data to trigger a deserialization error and execute arbitrary code on the target system [CVE-2017-11284]. The code will run with the privileges of the target service.

The software does not properly filter HTML code from user-supplied input before displaying the input [CVE-2017-11285]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Adobe ColdFusion software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can supply specially crafted XML External Entity (XXE) data to the target interface to obtain potentially sensitive informations on the target system with the privileges of the target service [CVE-2017-11286].

Daniel Lawson of Depth Security, Daniel Sayk of Telekom Security, and Nick Bloor of NCC Group reported these vulnerabilities.

Impact:   A remote user can execute arbitrary code on the target system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Adobe ColdFusion software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can obtain potentially sensitive information on the target system with the privileges of the target service.

Solution:   The vendor has issued a fix (11 Update 13, 2016 Update 5).
