SecurityTracker Alert ID:  1039924
SecurityTracker URL:  http://securitytracker.com/id/1039924
CVE Reference:   CVE-2017-12348, CVE-2017-12349   (Links to External Site)
Date:  Nov 30 2017
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network

Description:   Two vulnerabilities were reported in Cisco UCS Central. A remote user can hijack the target user's session. A remote user can conduct cross-site scripting attacks.

A remote user can conduct a session fixation attack to hijack a target user's session [CVE-2017-12349].

The software does not properly filter HTML code from user-supplied input before displaying the input [CVE-2017-12348]. 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 Cisco Unified Computing System Central 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.

The vendor has assigned bug IDs CSCvf71978 and CSCvf71986 to these vulnerabilities.

Application Security Consultant Indrajith.A.N reported this vulnerability.

Impact:   A remote user can hijack the target user's session.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Cisco Unified Computing System Central 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.
