Recently a 15 year old tech blogger and security researcher named Indrajeet bhuyan found and helped fix a XSS vulnerability in Photobucket.







He had previously found vulnerabilities in Samsung, Disqus, NDTV, Jabong, IIT Bombay and many others. 

Editor's Note: It is good to see that such young hackers are acting responsibly and reporting vulnerabilities instead of simply defacing the site or using the vulnerabilities for malicious motives.I hope that Mr.Indrajeet bhuyan continues this.
Recently, EHN received a news report from Tunisian Cyber Army and Al Qaida Electronic Army in which the hackers claimed to have infected the Pentagon administrator, as part of their on going operation called "#opBlackSummer".

The attack was happened after hackers identified a reflected cross site scripting(XSS) vulnerability in one of the sub domain of Pentagon (g1arng.army.pentagon.mil).

POC:
g1arng.army.pentagon.mil/Programs/Pages/Default.aspx?Category="><script>alert("xss by tca and AQECA on pentagon")</script>

xss vulnerability

The hacker managed to exploit this vulnerability for sending malicious payload to the admin of Pentagon. Hackers claims that they got success in infecting them.

Hackers said they compromised  some important file and steal cookies from the pentagon mail. The security breach was done with collaboration with Chinese hackers.

At the time of writing, the vulnerability is not fixed. If the TCA claim is true, then this one will be the best example that demonstrate the severity of simple reflected xss. Yesterday, i have sent notification to Pentagon team about the vulnerability but there is no response from them.

In another mail, the team said the have hacked the state.gov with SQL injection vulnerability. 
An Information Security Researcher, Sukhwinder Singh, has identified a critical security flaw in one of the top Support ticket system provided by Zendesk.

The title field is vulnerable to Persistent Cross site scripting.   The researcher managed to create a ticket with this title : "><script>alert(/Sukhwinder Singh/)</script>.  

Even though the Developer of this app managed to sanitize the title before being displayed in the user end, he stored the title in the database without sanitizing.

The title is being sanitized every time it is being displayed in the page.  Unfortunately, they failed to remove the special characters before displaying the title in data-text attribute of Twitter_button code.


POC:

Today, Information Security Researcher QuisterTow come with interesting vulnerability finding in one of Top Search Engine website, Yahoo.

There is a cross site scripting vulnerability resides in the hk.promotions.yahoo.com domain.  The vulnerability is click based xss .  When i click the flash, it will display the xss code.

Poc code:
http://hk.promotions.yahoo.com/wedding2010/home_banner.swf?clickTAG=javascript:alert(/ E Hacking News /);

The above finding is really interesting one.  Just load the url and click in the flash content and it results in the code being executed.

At the time of writing, the vulnerability is still there .






Ravi Kariya, a Security Analyst from Cyber Octet Pvt. Ltd (facebook.com/cyberoctet) has discovered critical vulnerabilities in the official website (divyadutta.co.in) of famous Indian Actress Divya Dutta.

There are two SQL Injection vulnerability in the website.  One of the vulnerabilities resides in the  Press Clips page of the site(divyadutta.co.in/pressclipdetail.asp?id=7).  A malicious hacker can exploit this vulnerability and extract the database .

The other one is more critical one , it allows hackers to bypass authentication of the Login .  A malicious hacker can login into the website as admin(divyadutta.co.in/admin/) . This can be done by injecting the crafted password that will modify the sql query such that it allows hacker to login.

There is also Cross site scripting vulnerability in the contact us page(divyadutta.co.in/contact.asp ) .  Injecting the follow code in the fields and clicking the submit button executes the injected code:

"><script>alert('My Love For Divya Dutta')</script>




Ravi tried to contact the Divya dutta via email and Twitter but she fails to respond for his query.  It seems like that She doesn't realize the severity level of this security flaw. A BlackHat hacker is able to deface the site with these vulnerabilities.

I think she will respond after some blackhats attack the site, what do you think guys?

*Update*
After E hacking news published news about the vulnerability, the admin pulled down the divya dutta site. Now the site displays the following error message:

"Directory Listing Denied.This Virtual Directory does not allow contents to be listed."

Recently,  I(Sabari Selvan aka BreakTheSec) discovered a XSS vulnerability in Airtel website and  reported to them.  It seems like they neither reply nor patch the vulnerability , So it is better to publish my finding in this same post itself.


The POC code for my finding:
http://www.airtel.in/wps/wcm/connect/airtel.in/airtel.in/home/foryou/mobile/prepaid+services/reach+airtel/PG_FY_MB_Prepaid_ReachAirtel/?page=cs_m&CIRCLE=2&CIRCLENAME="><script>alert("BreakTheSec")</script>

The hackers who recently defaced Top level Domains of Turkmenistan by exploiting the vulnerability in NIC.tm, has discovered another vulnerability in the website.

They found that the few NIC websites uses the vulnerable version of Apache server(version 1.3.33) .   The version has a security flaw that exists in the handling of invalid Expect headers. Modifying the Expect header value to XSS code results in Cross site scripting attack.

GET / HTTP/1.1
Expect: <script>alert("E Hacking News")</script>
Host: nic.tm
Connection: Keep-alive
Accept-Encoding: gzip,deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0)
Acunetix-Product: WVS/8.0 (Acunetix Web Vulnerability Scanner - NORMAL)
Acunetix-Scanning-agreement: Third Party Scanning PROHIBITED
Acunetix-User-agreement: http://www.acunetix.com/wvs/disc.htm
Accept: */*

Expect Header xss attack


The vulnerability affects four NIC websites : www.nic.ac, www.nic.tm ,www.nic.io,www.nic.sh.

There is another important security flaw in the Apache server : Mod_rewrite which is vulnerable to buffer overflow(Vulnerability Details). 
A Security Researcher from crackhackforum.com, Rynaldo, has discovered multiple Vulnerabilities in one of the Biggest Antivirus company called "BitDefender".

The researcher claimed that he sent several emails to BitDenfender's team, butthey haven't responded nor fixed the vulnerabilities neither.

"The website is having several reflected XXS vulnerabilities and the CSRF
vulnerability. Also I have found a way to cause DOS attack on the local
server to take BitDefender temporarely down." Rynaldo said.

CSRF attack : https://my.bitdefender.com/en_us/my/#page=account.index hacker is able to perform CSRF attack to change the details on the user's profile.CSRF tokens aren't implemented and password isn't required to change information on the profile.

Reflected XSS

XSS attack :
"my.bitdefender.com/en_us/", this page will set the language specifications on the URL (en_us), but haven't secured it very well. That means by removing the language specification with our XSS payload then our XSS script will be executed. Language specifications are being forced on the URL on every page and that means we can inject our XSS in every page on "my.bitdefender.com".
An Indian Security Researcher , Suriya has discovered A reflected xss vulnerability in the AOL website, an American global brand company that develops, grows, and invests in brands and web sites. 

Initially , the researcher discovered the xss vulnerability in Dmoz. After notifying the "In partnership with AOL search" text in the Dmoz website, he decided to test the AOL also for the vulnerability and got success.

According to Researcher, the vulnerability was discovered five months ago.  He immediately tried to contact the AOL Security team.  Unfortunately, he is not able to find the contact address for the security team, so he tried to contact some emails provided in the site but they failed to respond properly.

AOL xss

After few months, he published the vulnerability details in his own blog on October 2012.  But the XSS vulnerability is still there and unfixed.

POC code for the AOL xss:
 http://www.aol.com/?icid=';alert(String.fromCharCode(69, 32, 72, 97, 99, 107, 105, 110, 103, 32, 78, 101, 119, 115))//'
POC code for the Dmoz:
 http://www.dmoz.org/search?q="><script>alert("E Hacking News")</script>


Dmoz XSS

"You might be wondering why I included the alexa.com rank for the site’s, that’s cause I wanted to show you all how even a small site has more instinctive to fix a vulnerability but AOL with its hundreds of workers could not even bother giving me a proper reply." Suriya said.

"Well I really dint know. But I think I wanted to show the world how people treat us and to tell AOL to follow the path of Paypal , Microsoft etc allowing people to at least securely report vulnerabilities ,even if you are not paying them at least acknowledge the people who give time and resources out of their lives to help you!"
An Information Security Researcher , Mahadev Subedi, from coolpokharacity.com has claimed to have discovered a Persistent Cross site scripting vulnerability in the Mediafire website(mediafire.com)

It seems like the vulnerability exists in the File uploading feature in the Mediafire.  The developers fails to sanitize the file name of the uploaded file.

Persistent xss vulnerability in Mediafire

"Whenever we upload file names containing encoded or decoded malicious XSS codes, it results in Cross Site Scripting ." The researcher said in the email.

For instance, if you create a file name with this code and upload it , it results in xss: 
"><img src=x onerror=alert(1)>.jpg.txt
Recently A security Researcher Frans Rosén discovered similar kind of vulnerability in the DropBox .
