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.

(1) WebSite:
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.

 

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)

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.

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

留言

 
 

binary_data_illustratio_450

 

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)

留言

6864_cTAUHWda_o-600x401

 

 

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.

 

 

mozilla_lxr_2_xss

 
 

mozilla_mxr_1_xss

 

 

 

POC Codes:

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

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

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

 

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

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.

 

 

(3) Vulnerability Disclosure:
The vulnerability have been reported to bugzilla.mozilla.org. Mozilla are dealing with this issue.

The web application indiatimes.com online website has a security problem. Hacker can exploit it by XSS bugs.

 

The code flaw occurs at Indiatimes’s URL links. Indiatimes only filter part of the filenames in its website. All URLs under Indiatimes’s “photogallery" and “top-llists" topics are affected.

Indiatimes uses part of the links under “photogallery" and “top-llists" topics to construct its website content without any checking of those links at all. This mistake is very popular in nowaday websites. Developer is not security expert.

The vulnerability can be attacked without user login. Tests were performed on Mozilla Firefox (26.0) in Ubuntu (12.04) and Microsoft 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:

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) Vulnerability Details:

 

6kbbs web application has a computer security problem. It can be exploited by weak encryption attacks. The software stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. A weak encryption scheme can be subjected to brute force attacks that have a reasonable chance of succeeding using current attack methods and resources.

 

Several 6kbbs products 0-day web cyber bugs have been found by some other bug hunter researchers before. 6kbbs has patched some of them. “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 web securities have been published here.

 

Source Code:

<?php

if(empty($row)){

$extrow=$db->row_select_one(“users","username='{$username}'");

if(!empty($extrow) && !empty($extrow[‘salt’])){

if(md5(md5($userpass).$extrow[‘salt’])==$extrow[‘userpass’]){

$row=$extrow;

$new_row[“userpass"]=$userpass_encrypt;

$new_row[“salt"]="";

$db->row_update(“users",$new_row,"id={$extrow[‘id’]}");

}

}

}

?>

 

 

Source Code From:
http://code.google.com/p/6kbbs/source/browse/trunk/convert/discuz72/loginext.php?r=16

 

We can see that “userpass" stored in cookie was encrypted using “$userpass" user password directly. And there is no “HttpOnly" attribute at all. Since md5 is used for the encryption, it is easy for hackers to break the encrypted message.

 

“The MD5 message-digest cryptography algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed in text format as a 32 digit hexadecimal number. Papers about it have been published on Eurocrypt, Asiacrypt and Crypto. Meanwhile, researchers focusing on it spread in Computer Science, Computer Engineering, IEEE and Mathematics. MD5 has been utilized in a wide variety of cryptographic applications, and is also commonly used to verify data integrity. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function, MD4. The source code in RFC 1321 contains a “by attribution" RSA license." (Wikipedia)
