Cacti Input Validation Flaw in 'spikekill.php' Lets Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1039208
SecurityTracker URL:  http://securitytracker.com/id/1039208
CVE Reference:   CVE-2017-12927   (Links to External Site)
Date:  Aug 18 2017
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in Cacti. A remote user can conduct cross-site scripting attacks.

The 'spikekill.php' script does not properly filter HTML code from user-supplied input in the 'method' parameter before displaying the input. 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 Cacti 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.

github user kevinoclam reported this vulnerability.
