[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1137) Potentially large security hole in Seam Captcha implementation

Potentially large security hole in Seam Captcha implementation -------------------------------------------------------------- Key: JBSEAM-1137 URL: http://jira.jboss.com/jira/browse/JBSEAM-1137 Project: JBoss Seam Issue Type: Bug Components: Security Affects Versions: 1.2.0.GA Environment: Any Reporter: Ian Hlavats I have been experiencing "holes" in the Seam captcha integration recently. The Seam documentation (section 21.1.1) recommends client-side state saving for JSF. The following scenario should point out a potential security issue with this approach. Suppose I have a JSF page with a typical user comment form on it that does not use Seam's captcha component. Now a malicious user scrapes my JSF page and stores a local copy on his computer, serialized UI component tree and all. In the meantime, I add Seam's captcha component to my JSF page, trusting it to cause a validation error when the form is submitted without the correct captcha text. Can the malicious user can now submit the previous copy of my form without the captcha component in the tree? I am using the MyFaces 1.1.4 JSF implementation.
