IBM WebSphere Portal Bugs Permit Cross-Site Scripting and Information Disclosure Attacks
SecurityTracker Alert ID:  1032970
SecurityTracker URL:  http://securitytracker.com/id/1032970
CVE Reference:   CVE-2015-1887, CVE-2015-1917, CVE-2015-1944   (Links to External Site)
Date:  Jul 17 2015
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): Portal 6.1, 7.0, 8.0, 8.5
Description:   Several vulnerabilities were reported in IBM WebSphere. A remote user can obtain potentially sensitive information on the target system. A remote user can conduct cross-site scripting attacks.

A remote user can send a specially crafted request to view potentially sensitive information on the target system [CVE-2015-1887]. Versions 7, 8.0, and 8.5 are affected.

The IBM Active Content Filtering component does not properly filter HTML code from user-supplied input before displaying the input [CVE-2015-1917]. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the IBM WebSphere Portal 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 code will originate from the site running the IBM WebSphere Portal 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. Versions 8.0.0.1 and 8.5 are affected.

Impact:   A remote user can obtain potentially sensitive information 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 IBM WebSphere Portal 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.
