Henri Yandell commented on LANG-572:
------------------------------------
OSAPI->ESAPI :) Brain typo on my part.
Other conversion functions - I wouldn't say ISO entities specifically as it
depends on the format as to the notion of entity, but I'd say that's generally
true. For an extreme example the escapeCsv wasn't intended to protect against
security or weird issues in MS Excel.
> [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
>
> 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).
