Christian Bauer closed JBSEAM-2204.
-----------------------------------
Fix Version/s: 2.0.1.GA
Resolution: Done
Resolved this (I hope) by not allowing double or single quotes in HTML attribute values.
This should prevent attribute-based attacks, such as simply embedding Javascript in the
HREF attribute.
Also removed the <embed> and <object> tags from the allowed list, these would
open up XSS holes by executing Flash movies in the page context.
Potential XSS issue in seam text with allowed href attribute
------------------------------------------------------------
Key: JBSEAM-2204
URL:
http://jira.jboss.com/jira/browse/JBSEAM-2204
Project: JBoss Seam
Issue Type: Bug
Components: Wiki
Affects Versions: 2.0.0.GA
Reporter: Christian Bauer
Assigned To: Christian Bauer
Priority: Critical
Fix For: 2.0.1.GA
We allow <a href="foo"/> in Seam Text, which can potentially be abused to
inject Javascript executed in the context of the page. Need to evaluate impact of leaving
or removing.
