<h1>HTML Purifier XSS Attacks Smoketest</h1>
|
|
<p>XSS attacks are from
|
|
<a href="http://ha.ckers.org/xss.html">http://ha.ckers.org/xss.html</a>.</p>
|
|
<p><strong>Caveats:</strong>
|
|
The last segment of tests regarding blacklisted websites is not
|
|
applicable at the moment, but when we add that functionality they'll be
|
|
relevant. Most XSS broadcasts its presence by spawning an alert dialogue.
|
|
The displayed code is not strictly correct, as linebreaks have been forced for
|
|
readability. Linewraps have been marked with <tt>»</tt>. Some tests are
|
|
omitted for your convenience. Not all control characters are displayed.</p>
