------------------------------
Fix Version/s: 6.8.0
(was: 6.7.1)
> Struts 2 XSS vulnerability with <s:textfield> when <s:include> is used.
> -----------------------------------------------------------------------
>
> Key: WW-4625
> URL: https://issues.apache.org/jira/browse/WW-4625
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.3.24, 2.3.28
> Environment: Operating System: Windows 7(N/A).
> Application Server: Tomcat 6(any server running on JRE1.6 or before JRE).
> Java: jdk1.5.0.11.
> Developloment Framework: Struts 2.3.28, 2.3.24.1.
> Browser: FireFox 38.0.1.
> Reporter: Naozumi Taromaru
> Priority: Major
> Labels: struts2, vulnerability, xss
> Fix For: 6.8.0
>
>
> <s:include> tag and JspTemplateEngine use
> org.apache.struts2.components.Include#include.
> (I use <s:include> tag.)
> The included page is encoded by response character encoding(default is
> ISO-8859-1(ServletResponse)).
> But encoded result is decoded by 'request' character encoding(default is
> UTF-8(@Inject(StrutsConstants.STRUTS_I18N_ENCODING))).
> org.apache.struts2.components.Include use wrong character encoding.
> If request and response character encoding are specifically configured to
> same character encoding,
> there are no problems.
> However, if request and response character encoding are not specifically
> configured,
> (or <%@ page contentType="text/html; charset=ISO-8859-1" %> is written in JSP
> only,)
> the included page is encoded by ISO-8859-1 and decoded by UTF-8.
> By using old decoding rule of UTF-8(enable on JRE1.5.0_16 or before and
> JRE1.6.0_10 or before),
> XSS vulnerability occurs, even if input value is sanitized when output as
> <s:textfield>.
> Please refer to description of WW-4507 for sample attack parameter
> information.
> Please refer to my comment written in WW-4507 for more analysis information.
> P.S.
> I'm thinking WW-4507(S2-028) has been caused by this.
> (WW-4507(S2-028) is not fixed in 2.3.28.)
> But if it's different, please show the hidden reproduction condition to
> WW-4507.
