Mike Noordermeer commented on CXF-6216:
---------------------------------------
A security scan pointed out an actual XSS issue with this. By including a
matrix parameter it is possible to include arbitrary code in the page.
Something like this is enough to include an onmouseover (with javascript):
{{GET /api/;"onmouseover='nwsh(9102)'bad=" HTTP/1.1}}
Note that you should send the " unescaped (browsers usually escape this, try a
telnet session).
Example conversation, using CXF 3.1.5, Tomcat 7.0.69, Java 8u92:

> No output sanitizing in FormattedServiceListWriter

> Key: CXF-6216
> URL: https://issues.apache.org/jira/browse/CXF-6216
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.0.1
> Reporter: Donald Kwakkel
>
> No output sanitizing is done, which makes the code vulnerable for injection.
> I do not have a specific use case, but it is good habit to do. Maybe you can
> use the OWASP Sanitizer:
> https://www.owasp.org/index.php/OWASP_Java_HTML_Sanitizer_Project
> One example from the file:
> writer.write("<span class=\"field\">Endpoint address:</span> " +
> "<span class=\"value\">"
> + absoluteURL + "</span>");
