Henri Yandell updated LANG-572:
-------------------------------
Fix Version/s: Discussion
> [XSS] StringEscapeUtils.escapeHtml() must escape ' chars to '
> ------------------------------------------------------------------
>
> Key: LANG-572
> URL: https://issues.apache.org/jira/browse/LANG-572
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Affects Versions: 2.4
> Environment: Operating System: All
> Platform: All
> Reporter: Keisuke Kato
> Priority: Minor
> Fix For: Discussion
>
>
> If developers putting untrusted data into attribute values using the single
> quote character ' and StringEscapeUtils.escapeHtml() like:
> <input type='text' name='input'
> value=*'<%=StringEscapeUtils.escapeHtml(request.getParameter("input"))%>'*>
> Then, the attacker is able to break out of the HTML attribute context like:
> hxxp://example.org/?input=*' onfocus='alert(document.cookie);' id='*
> <input type='text' name='input'
> value='*'onfocus='alert(document.cookie);'id='*'>
> I think [LANG\-122|https://issues.apache.org/jira/browse/LANG-122] is not
> truly fixed from this aspect (XSS).
