IBM WebSphere Input Validation Flaws in Certain Sample Scripts Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1015360
SecurityTracker URL:  http://securitytracker.com/id/1015360
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Dec 15 2005
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 6.0
Description:   A vulnerability was reported in IBM WebSphere in some sample scripts. A remote user can conduct cross-site scripting attacks. A remote user can also determine valid user account names on the target system.

Several scripts do not properly filter HTML code from user-supplied input before displaying the input. 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 WebSphere 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 'E-mail address' field in the 'PlantsByWebSphere/login.jsp' script is affected.

The 'message' field in the '/TechnologySample/BulletinBoard' script is affected.

The 'Email address' field in the '/TechnologySamples/Subscription/SubscriptionJSP.jsp' script is affected.

The 'Movie Name', 'Movie Reviewer', and 'Movie Review' fields in the '/TechnologySamples/MovieReview2_1/' script is also affected.

The 'PlantsByWebSphere/login.jsp' script provides a different response to an authentication attempt for a valid user account name than for an invalid user account name. As a result, a remote user can conduct a brute force guessing attack to determine valid user account names on the target system.
