> ---------------------------------------------
>
> Key: DELTASPIKE-1389
> URL: https://issues.apache.org/jira/browse/DELTASPIKE-1389
> Project: DeltaSpike
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: JSF-Module
> Affects Versions: 1.9.1
> Reporter: Matthias Walliczek
> Assignee: Mark Struberg
> Priority: Major
> Labels: security
> Fix For: 1.9.2
>
>
> Despide that it was improving in
> https://issues.apache.org/jira/browse/DELTASPIKE-1307, the sanitizing of the
> dswid parameter is still imperfect.
> PoC: request a page with "xzy.jsf?dswid=',danger,'" will render "danger" as
> variable into the javascript code.
> Solution: Instead of filtering "(", "<" and "&" as a black list attempt which
> is not recommended by the OWASP, only numeric characters and "-" should be
> allowed as white list approach.
