[ https://issues.apache.org/jira/browse/TEXT-43?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rob Tompkins updated TEXT-43:
-----------------------------
Fix Version/s: 1.1
> [XSS] StringEscapeUtils.escapeHtml() must escape ' chars to '
> ------------------------------------------------------------------
>
> Key: TEXT-43
> URL: https://issues.apache.org/jira/browse/TEXT-43
> Project: Commons Text
> Issue Type: Improvement
> Environment: Operating System: All
> Platform: All
> Reporter: Keisuke Kato
> Priority: Minor
> Fix For: 1.1
>
>
> 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).
