PROBLEM:

Apache Wicket Input Validation Flaw Permits Cross-Site Scripting Attacks

PLATFORM:

Apache Software Foundation Apache Wicket 1.5.5
Apache Software Foundation Apache Wicket 1.5-RC5.1
Apache Software Foundation Apache Wicket 1.4.20
Apache Software Foundation Apache Wicket 1.4.18
Apache Software Foundation Apache Wicket 1.4.17
Apache Software Foundation Apache Wicket 1.4.16

ABSTRACT:

A vulnerability was reported in Apache Wicket

reference LINKS:

Apache Wicket
SecurityTracker Alert ID:  1027508
Bugtraq ID:  55445
CVE-2012-3373

IMPACT ASSESSMENT:

Medium

Discussion:

The software does not properly filter HTML code from user-supplied input in ajax links 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 Apache Wicket 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.

Impact:

Certain unspecified input is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Solution:

The vendor has issued a fix.
