<<a rel="nofollow" href="https://github.com/mitreid-connect/OpenID-Connect-Java-Spring-Server">https://github.com/mitreid-connect/OpenID-Connect-Java-Spring-Server</a>> version
1.3.3 and earlier is vulnerable to Cross-Site Scripting; the users name is
included in *topbar.tag* and *header.tag* without being sanitized. A user
can set their name to a value like:
Test</script><script>alert(1)</script>
Which will be included in JSON used by a JavaScript function in *header.tag*
:
// get the info of the current user, if available (null otherwise)
</pre><blockquote style="border-left: #5555EE solid 0.2em; margin: 0em; padding-left: 0.85em"><pre style="margin: 0em;"> function getUserInfo() {
return {"sub":"12318767","name":"
*Test</script><script>alert(1)</script>*
Test","preferred_username":"Test","given_name":"Test</script><script>alert(1)</script>","family_name":"Test","email":"
test () test com","email_verified":true};}
</pre></blockquote><pre style="margin: 0em;">
A name such as:
Test<script>alert(1)</script>
would also work; it is included in the page when menus are created by
*topbar.tag*:
<!-- use a simplified user button system when collapsed -->
</pre><blockquote style="border-left: #5555EE solid 0.2em; margin: 0em; padding-left: 0.85em"><pre style="margin: 0em;"><ul class="nav hidden-desktop">
<li><a href="manage/#user/profile">*Test<script>alert(1)</script>*
Test</a></li>
<li class="divider"></li>
<li><a href="" class="logoutLink"><i class="icon-remove"></i> Log
out</a></li>
