eBay Covert Redirect Vulnerability Based on Googleads.g.doubleclick.net

(1) WebSite:
ebay.com



“eBay Inc. (stylized as ebay, formerly eBay) is an American multinational corporation and e-commerce company, providing consumer to consumer & business to consumer sales services via Internet. It is headquartered in San Jose, California. eBay was founded by Pierre Omidyar in 1995, and became a notable success story of the dot-com bubble. Today, it is a multi-billion dollar business with operations localized in over thirty countries.

 

The company manages eBay.com, an online auction and shopping website in which people and businesses buy and sell a broad variety of goods and services worldwide. In addition to its auction-style sales, the website has since expanded to include “Buy It Now” shopping; shopping by UPC, ISBN, or other kind of SKU (via Half.com); online classified advertisements (via Kijiji or eBay Classifieds); online event ticket trading (via StubHub); online money transfers (via PayPal) and other services.” (Wikipedia)

 



(2) Vulnerability Description:

eBay web application has a computer cyber security problem. Hacker can exploit it by Covert Redirect attacks.

The vulnerability occurs at “ebay.com/rover” page with “&mpre” parameter, i.e.

http://rover.ebay.com/rover/1/711-67261-24966-0/2?mtid=691&kwid=1&crlp=1_263602&itemid=370825182102&mpre=http://www.google.com

The vulnerability can be attacked without user login. Tests were performed on Firefox (26.0) in Ubuntu (12.04) and IE (9.0.15) in Windows 7.


 

 

 

(2.1) When a user is redirected from eBay to another site, eBay will check whether the redirected URL belongs to domains in eBay’s whitelist, e.g.
google.com

If this is true, the redirection will be allowed.

 

However, if the URLs in a redirected domain have open URL redirection vulnerabilities themselves, a user could be redirected from eBay to a vulnerable URL in that domain first and later be redirected from this vulnerable site to a malicious site. This is as if being redirected from eBay directly.

 

One of the vulnerable domain is,
http://googleads.g.doubleclick.net (Google’s Ad system)

 

 

 

(2.2) Use one of webpages for the following tests. The webpage address is “http://itinfotech.tumblr.com/“. We can suppose that this webpage is malicious.

(3) What is Covert Redirect?

Covert Redirect is a class of security bugs disclosed in May 2014. It is an application that takes a parameter and redirects a user to the parameter value without sufficient validation. This often makes use of Open Redirect and XSS vulnerabilities in third-party applications.

 

Covert Redirect is also related to single sign-on. It is known by its influence on OAuth and OpenID. Hacker may use it to steal users’ sensitive information. Almost all OAuth 2.0 and OpenID providers worldwide are affected. Covert Redirect was found and dubbed by a Mathematics PhD student Wang Jing from School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore.

After Covert Redirect was published, it is kept in some common databases such as SCIP, OSVDB, Bugtraq, and X-Force. Its scipID is 13185, while OSVDB reference number is 106567. Bugtraq ID: 67196. X-Force reference number is 93031.

The Weather Channel at Least 76.3% Links Vulnerable to XSS Attacks

 

 

Domain Description:
http://www.weather.com/

 

“The Weather Channel is an American basic cable and satellite television channel which broadcasts weather forecasts and weather-related news and analyses, along with documentaries and entertainment programming related to weather. Launched on May 2, 1982, the channel broadcasts weather forecasts and weather-related news and analysis, along with documentaries and entertainment programming related to weather.”

 

“As of February 2015, The Weather Channel was received by approximately 97.3 million American households that subscribe to a pay television service (83.6% of U.S. households with at least one television set), which gave it the highest national distribution of any U.S. cable channel. However, it was subsequently dropped by Verizon FiOS (losing its approximately 5.5 millions subscribers), giving the title of most distributed network to HLN. Actual viewership of the channel averaged 210,000 during 2013 and has been declining for several years. Content from The Weather Channel is available for purchase from the NBCUniversal Archives.” (Wikipedia)

 

 

 

 

Vulnerability description:


The Weather Channel has a cyber security problem. Hacker can exploit it by XSS bugs.

 

Almost all links under the domain weather.com are vulnerable to XSS attacks. Attackers just need to add script at the end of The Weather Channel’s URLs. Then the scripts will be executed.

 

10 thousands of Links were tested based a self-written tool. During the tests, 76.3% of links belong to weather.com were vulnerable to XSS attacks.

 

The reason of this vulnerability is that Weather Channel uses URLs to construct its HTML tags without filtering malicious script codes.

 

The vulnerability can be attacked without user login. Tests were performed on Firefox (34.0) in Ubuntu (14.04) and IE (9.0.15) in Windows 8.

http://www.weather.com/news/main/“><img src=x onerror=prompt(‘justqdjing’)>

 

 

The Weather Channel has patched this Vulnerability in late November, 2014 (last Week). “The Full Disclosure mailing list is a public forum for detailed discussion of vulnerabilities and exploitation techniques, as well as tools, papers, news, and events of interest to the community. FD differs from other security lists in its open nature and support for researchers’ right to decide how to disclose their own discovered bugs. The full disclosure movement has been credited with forcing vendors to better secure their products and to publicly acknowledge and fix flaws rather than hide them. Vendor legal intimidation and censorship attempts are not tolerated here!” A great many of the fllowing web securities have been published here, Buffer overflow, HTTP Response Splitting (CRLF), CMD Injection, SQL injection, Phishing, Cross-site scripting, CSRF, Cyber-attack, Unvalidated Redirects and Forwards, Information Leakage, Denial of Service, File Inclusion, Weak Encryption, Privilege Escalation, Directory Traversal, HTML Injection, Spam. This bug was published at The Full Disclosure in November, 2014.

Amazon Covert Redirect Bug Based on Kindle Daily Post, Omnivoracious, Car Lust

— Amazon Covert Redirect Based on Kindle Daily Post, Omnivoracious, Car Lust & kindlepost.com omnivoracious.com carlustblog.com Open Redirect Web Security Vulnerabilities

“Amazon.com, Inc. (/ˈæməzɒn/ or /ˈæməzən/) is an American electronic commerce company with headquarters in Seattle, Washington. It is the largest Internet-based retailer in the United States. Amazon.com started as an online bookstore, but soon diversified, selling DVDs, Blu-rays, CDs, video downloads/streaming, MP3 downloads/streaming, software, video games, electronics, apparel, furniture, food, toys and jewelry. The company also produces consumer electronics—notably, Amazon Kindle e-book readers, Fire tablets, Fire TV and Fire Phone — and is a major provider of cloud computing services. Amazon also sells certain low-end products like USB cables under its inhouse brand AmazonBasics. Amazon has separate retail websites for United States, United Kingdom & Ireland, France, Canada, Germany, The Netherlands, Italy, Spain, Australia, Brazil, Japan, China, India and Mexico. Amazon also offers international shipping to certain other countries for some of its products. In 2011, it had professed an intention to launch its websites in Poland and Sweden.” (Wikipedia)

 

All kindlepost.com, omnivoracious.com, carlustblog.com are websites belonging to Amazon.

“The Kindle Post keeps Kindle customers up-to-date on the latest Kindle news and information and passes along fun reading recommendations, author interviews, and more.”

“Omnivoracious is a blog run by the books editors at Amazon.com. We aim to share our passion for the written word through news, reviews, interviews, and more. This is our space to talk books and publishing frankly and we welcome participation through comments. Please visit often or add us to your favorite RSS reader to keep up on the latest information.”

“Car Lust is, very simply, where interesting cars meet irrational emotion. It’s a deeply personal exploration of the hidden gems of the automotive world; a twisted look into a car nut’s mind; and a quirky look at the broader automotive universe – a broader universe that lies beneath the new, the flashy, and the trendy represented in the car magazines.”

Vulnerabilities Description:

Amazon has a computer bug security problem. Both Amazon itself and its websites are vulnerable to different kind of attacks. This allows hackers to do phishing attacks to Amazon users.

 

When a user is redirected from amazon to another site, amazon will check a variable named “token”. Every redirected website will be given one token. This idea is OK. However, all URLs related to the redirected website use the same token. This means if the authenticated site itself has Open Redirect vulnerabilities. Then victims can be redirected to any site from Amazon.

 

The program code flaw can be attacked without user login. Tests were performed on Microsoft IE (9 9.0.8112.16421) of Windows 7, Mozilla Firefox (37.0.2) & Google Chromium 42.0.2311 (64-bit) of Ubuntu (14.04.2),Apple Safari 6.1.6 of Mac OS X v10.9 Mavericks.

Use a website for the following tests. The website is “http://www.diebiyi.com/articles“. Suppose this website is malicious,

(2) Vulnerability Details:

NetCat web application has a computer security bug problem. It can be exploited by HTML Injection attacks. Hypertext Markup Language (HTML) injection, also sometimes referred to as virtual defacement, is an attack on a user made possible by an injection vulnerability in a web application. When an application does not properly handle user supplied data, an attacker can supply valid HTML, typically via a parameter value, and inject their own content into the page. This attack is typically used in conjunction with some form of social engineering, as the attack is exploiting a code-based vulnerability and a user’s trust.

Several NetCat products 0-day vulnerabilities have been found by some other bug hunter researchers before. NetCat has patched some of them. Web Security Watch is an aggregator of security reports coming from various sources. It aims to provide a single point of tracking for all publicly disclosed security issues that matter. “Its unique tagging system enables you to see a relevant set of tags associated with each security alert for a quick overview of the affected products. What’s more, you can now subscribe to an RSS feed containing the specific tags that you are interested in – you will then only receive alerts related to those tags.” It has published suggestions, advisories, solutions details related to cyber security vulnerabilities.

 

(2.1) The programming code flaw occurs at “/catalog/search.php?” page with “&q” parameter.

FC2 Online Web Service Open Redirect (Unvalidated Redirects and Forwards) Cyber Security Vulnerabilities

 

Domain:
fc2.com

“FC2 (founded July 20, 1999) is a popular Japanese blogging host, the third most popular video hosting service in Japan (after YouTube and Niconico), and a web hosting company headquartered in Las Vegas, Nevada. It is the sixth most popular website in Japan overall (as of January 2014). FC2 is an abbreviation of “Fantastic Kupi-Kupi (クピクピ)”. It is known to allow controversial adult content such as pornography and hate speech (unlike many of its competitors). The company uses rented office space for its headquarters which it shares with many other U.S.-based businesses. It also pays taxes in the United States. The physical servers are located in the United States. However, it is believed that the majority of the company and its users (including employees) are located within Japan” (Wikipedia)

 

The Alexa rank of fc2.com is 52 on February 18 2015. It is the toppest Japanese local website sevice.

 

 

 

(1) Vulnerability Description:

FC2 online web service has a computer cyber security bug problem. It can be exploited by Open Redirect (Unvalidated Redirects and Forwards) attacks. Here is the description of Open Redirect: “An open redirect is an application that takes a parameter and redirects a user to the parameter value without any validation. This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it.” One consequences of it is Phishing. (OWASP)

 

The program code flaw can be attacked without user login. Tests were performed on Microsoft IE (9 9.0.8112.16421) of Windows 7, Mozilla Firefox (37.0.2) & Google Chromium 42.0.2311 (64-bit) of Ubuntu (14.04.2),Apple Safari 6.1.6 of Mac OS X v10.9 Mavericks.

 

In fact, during the test, it is not hard to find URL Redirection bugs in FC2. Maybe fc2.com pays little attention to mitigate these Vulnerabilities. These bugs were found by using URFDS.

 

 

 

(2) Use one of webpages for the following tests. The webpage address is “http://securitypost.tumblr.com/“. Can suppose that this webpage is malicious.

 

 

Vulnerability Disclosure:
Those vulnerabilities were reported to Rakuten, they are still unpatched.

プログラムコードの欠陥は、ユーザのログインなしで攻撃される可能性があります。テストは、Windows 7のMicrosoftのIE(9 9.0.8112.16421)で行われた、Mozilla Firefoxの(37.0.2)&グーグルクロム42.0.2311のUbuntuの(64ビット)(14.04.2)はMac OSのアップルのSafari 6.1.6 X v10.9マーベリックス。

 

実際には、テスト時には、FC2内のURLリダイレクトのバグを見つけることは難しいことではありません。多分fc2.comは、これらの脆弱性を軽減するためにはほとんど注意を払っています。
