JQuery Code alert neatly produced by DetectJQuery user script!

[polonus]

Code JS Query alert on page:  meta-header.php - Undefined property: stdClass::$1
PHP Error was encountered when trying to get property of non-object in www wp content content theme nieuws//...///meta-header.php on website:  htxp://nieuws.nl/
echo $row->$id; should be changed  to echo $row->id;   Info credits: newman
db function should be used to fetch results, Info credits Girish

I use DetectJQuery user script with Tampermonkey inside Google Chrome.
There is where this webpage turned up the code alert 

See: http://linkeddata.informatik.hu-berlin.de/uridbg/index.php?url=http://nieuws.nl/wp-content/themes/nieuws_hoofd/assets/vendor/jquery/dist/jquery.min.js&acceptheader=&useragentheader=

Update: the alert subsided. Might have been just silenced: http://php.net/manual/en/language.operators.errorcontrol.php

My Tampermonkey detectJQuery script alerted me to JQuery version 1.7.2 used on a website
and so I could conclude this version is vulnerable to Selector XSS with class Attribute ('. XSS_VECTOR')

On this site I detect jQuery 1.8.2 vulnerabilities -> http://webwereld.nl/
and found it vulnerable to malicious javascript code injections, read: http://stackoverflow.com/questions/11169894/can-malicious-javascript-code-be-injected-trough
info credits go to Mahn.
And also found vulnerable here: http://domstorm.skepticfx.com/modules?id=529bbe6e125fac0000000003

Just another example here: http://ruwix.com/online-rubiks-cube-solver-program/solution.php?cube=0122211641214526461312335554336644342365352636411465525&x=1
JQuery 1.3.2 enabled  Vulnerable version: http://stackoverflow.com/questions/25751829/jquery-cross-site-scripting-what-was-this

P.S. More outdated software on that particular website: HTTP Server: nginx (Cloudflare)
PHP Version: 5.2.17 (Outdated) -> http://www.cvedetails.com/version/106044/PHP-PHP-5.2.17.html

Realizing the jQuery version issues everywhere, I just launched the Online Lint and had some JQuery code from here:
http://www.webpagescreenshot.info/img/5515e61ac6eb29-30626131
JQuery version 1.11.1 and the output of js! Lint Online: http://www.webpagescreenshot.info/img/5515e64d7e4495-32699518 and what should be done to comply with coding standards. -> http://javascript.crockford.com/code.html
On that website:
http://fetch.scritch.org/%2Bfetch/?url=http%3A%2F%2Fwhisper.pr&useragent=Fetch+useragent&accept_encoding=
we find JQuery versions 1.11.1 and 1.2.1 and again the JQuery versions are almost never updated and reflect the version of the time of creation.

Hi Polonus,

Most website owners don't have a server script to automatically update jQuery and other libraries. Just viewing the source of a random site I use makes use of a jquery-latest.js, which is actually jQuery 1.6.2, not at all the latest.

There is a recorded vulnerability for jQuery 1.6.3 and below here: https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-4969 There could be more out there and this does not put the website in a good position, especially if it makes use of potential injection-prone code.

Hi !Donovan,

I wonder if this vulnerability described in the following link is still open (well it has been patched at long last): http://webcache.googleusercontent.com/search?q=cache:UGkNI5vxC_UJ:sijmen.ruwhof.net/weblog/256-cross-site-scripting-in-millions-of-web-sites+&cd=3&hl=nl&ct=clnk&gl=nl
They finally fixed this in November 2014: http://www.securityweek.com/developers-fix-xss-vulnerability-jquery-validation-plugin-script
Most vulnerabilties for JQuery are of a Cross Site Scripting nature, well lest other security measures has not been brought into place.

In addition, developers usually use jQuery libraries as a plug-and-play product, which doesn't require maintenance apart from library updates.

Because jQuery libraries are minified and infrequently reviewed by those using them, jQuery becomes a good place to hide malicious code. Such malicious code usually attempts to deliver malware to as many users as possible.

Quote from Ben-Hayak.

Just to show how easy this is to inject JQuery onto any webpage that has not got it, use this bookmarklet

Code: [Select]

javascript:var element1=document.createElement("script");element1.src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js";element1.type="text/javascript";document.getElementsByTagName("head")[0].appendChild(element1); Inspiration for the bookmarklet from http://ww1.tutkiun.com/2010/07/load-javascript-after-pageload.html
