Daily Mail Registration Page Unvalidated Redirects and Forwards & XSS Web Security Problem

Daily Mail Registration Page Unvalidated Redirects and Forwards & XSS Web Security Problem


Website Description:
"The Daily Mail is a British daily middle-market tabloid newspaper owned by the Daily Mail and General Trust. First published in 1896 by Lord Northcliffe, it is the United Kingdom's second biggest-selling daily newspaper after The Sun. Its sister paper The Mail on Sunday was launched in 1982. Scottish and Irish editions of the daily paper were launched in 1947 and 2006 respectively. The Daily Mail was Britain's first daily newspaper aimed at the newly-literate "lower-middle class market resulting from mass education, combining a low retail price with plenty of competitions, prizes and promotional gimmicks", and was the first British paper to sell a million copies a day. It was at the outset a newspaper for women, the first to provide features especially for them, and as of the second-half of 2013 had a 54.77% female readership, the only British newspaper whose female readers constitute more than 50% of its demographic. It had an average daily circulation of 1,708,006 copies in March 2014. Between July and December 2013 it had an average daily readership of approximately 3.951 million, of whom approximately 2.503 million were in the ABC1 demographic and 1.448 million in the C2DE demographic. Its website has more than 100 million unique visitors per month." (Wikipedia)


One of its website's Alexa rank is 93 on January 01 2015. The website is one of the most popular websites in the United Kingdom.


The Unvalidated Redirects and Forwards problem has not been patched, while the XSS problem has been patched.






(1) Daily mail Registration Page Unvalidated Redirects and Forwards Web Security Problem


(1.1) Vulnerability Description:
Daily online websites have a cyber security problem. Hacker can exploit it by Open Redirect (Unvalidated Redirects and Forwards) attacks. During the tests, all Daily mail websites (Daily Mail, Mail on Sunday & Metro media group) use the same mechanism. These websites include dailymail.co.uk, thisismoney.co.uk, and mailonsunday.co.uk.











































Google Dork:
"Part of the Daily Mail, The Mail on Sunday & Metro Media Group"


The vulnerability occurs at "&targetUrl" parameter in "logout.html?" page, i.e.
http://www.dailymail.co.uk/registration/logout.html?targetUrl=http%3A%2F%2Fgoogle.com





(1.2.1) Use the following tests to illustrate the scenario painted above.

The redirected webpage address is "http://diebiyi.com/articles". Can suppose that this webpage is malicious.

Vulnerable URLs:

Blog Details:



(1.2.2) The program code flaw can be attacked without user login. Tests were performed on Microsoft IE (9 9.0.8112.16421) of Windows 8, Mozilla Firefox (37.0.2) & Google Chromium 42.0.2311 (64-bit) of Ubuntu (14.04.2)，and Apple Safari 6.1.6 of Mac OS X v10.9 Mavericks.

These bugs were found by using URFDS (Unvalidated Redirects and Forwards Detection System).





(1.2) Description of Open Redirect:
Here is the description of Open Redirect: "A web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a Redirect. This simplifies phishing attacks. An http parameter may contain a URL value and could cause the web application to redirect the request to the specified URL. By modifying the URL value to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials. Because the server name in the modified link is identical to the original site, phishing attempts have a more trustworthy appearance." (From CWE)




(1.3) Vulnerability Disclosure:
These vulnerabilities have not been patched.






(2) Daily Mail Website XSS Cyber Security Zero-Day Vulnerability


(2.1) Vulnerability description:
DailyMail has a security problem. Criminals can exploit it by XSS attacks.

The vulnerability occurs at "reportAbuseInComment.html?" page with "&commentId" parameter, i.e.
http://www.dailymail.co.uk/home/reportAbuseInComment.html?articleId=346288&commentId=877038



POC Code:
http://www.dailymail.co.uk/home/reportAbuseInComment.html?articleId=346288&commentId="><img src=x onerror=prompt('justqdjing')>



The vulnerability can be attacked without user login. Tests were performed on Mozilla Firefox (34.0) in Ubuntu (14.04) and Microsoft IE (9.0.15) in Windows 7.






















(2.2) 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. Cross-site scripting carried out on websites accounted for roughly 84% of all security vulnerabilities documented by Symantec as of 2007. Their effect may range from a petty nuisance to a significant security risk, depending on the sensitivity of the data handled by the vulnerable site and the nature of any security mitigation implemented by the site's owner." (Wikipedia)




(2.3) Vulnerability Disclosure:
This vulnerability has been patched.

TeleGraph All Photo (Picture) Pages Have Been Vulnerable to XSS Cyber Attacks


Website Description:
http://www.telegraph.co.uk


"The Daily Telegraph is a British daily morning English-language broadsheet newspaper, published in London by Telegraph Media Group and distributed throughout the United Kingdom and internationally. The newspaper was founded by Arthur B. Sleigh in June 1855 as The Daily Telegraph and Courier, and since 2004 has been owned by David and Frederick Barclay. It had a daily circulation of 523,048 in March 2014, down from 552,065 in early 2013. In comparison, The Times had an average daily circulation of 400,060, down to 394,448. The Daily Telegraph has a sister paper, The Sunday Telegraph, that was started in 1961, which had circulation of 418,670 as of March 2014. The two printed papers currently are run separately with different editorial staff, but there is cross-usage of stories. News articles published in either, plus online Telegraph articles, may also be published on the Telegraph Media Group's www.telegraph.co.uk website, all under The Telegraph title." (From Wikipedia)




(1) Vulnerability Description:
Telegraph has a Web security bug problem. It is vulnerable to XSS attacks. In fact, all its photo pages are vulnerable to XSS (Cross-Site Scripting) vulnerabilities. Telegraph's picture pages use "&frame" as its parameter. All its web pages use "&frame" are vulnerable to the bugs. Those vulnerabilities have been patched now.


Examples of Vulnerable Links:



POC Code:


The vulnerability can be attacked without user login. Tests were performed on Firefox (37.02) in Ubuntu (14.04) and IE (8.0. 7601) in Windows 7. The bugs found by using CSXDS.


































































 







(2) XSS Description:
The description of XSS is: "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."

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.



















POC Codes, e.g.

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







POC Video:






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.

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.
