Product Introduction Overview:

“VuFind is a library resource portal designed and developed for libraries by libraries. The goal of VuFind is to enable your users to search and browse through all of your library’s resources by replacing the traditional OPAC to include: Catalog Records, Locally Cached Journals, Digital Library Items, Institutional Repository, Institutional Bibliography, Other Library Collections and Resources. VuFind is completely modular so you can implement just the basic system, or all of the components. And since it’s open source, you can modify the modules to best fit your need or you can add new modules to extend your resource offerings. VuFind runs on Solr Energy. Apache Solr, an open source search engine, offers amazing performance and scalability to allow for VuFind to respond to search queries in milliseconds time. It has the ability to be distributed if you need to spread the load of the catalog over many servers or in a server farm environment. VuFind is offered for free through the GPL open source license. This means that you can use the software for free. You can modify the software and share your successes with the community! Take a look at our VuFind Installations Wiki page to see how a variety of organizations have taken advantage of VuFind’s flexibility. If you are already using VuFind, feel free to edit the page and share your accomplishments. “

Product Introduction Overview:

“Your search to find the best photo gallery has led you to the most feature rich, best performing, and most widely used gallery available today. PhotoPost is the best way to offer your users the ability to upload, show off, share, discuss, and rate photos and videos on your site. We originally created PhotoPost in 2001 for TechIMO.com, our parent company’s own tech discussion website with 2 Million forum posts and 200,000 users, and within weeks we were inundated with requests, so we decided to develop it into a product. Over the past 8 years, PhotoPost has undergone more than 100 “dot” updates by a team of expert developers to add features, tweak performance, and maximize stability. Always in high demand, PhotoPost has been purchased by a staggering 14,500 websites. PhotoPost is most popular amongst vBulletin forum owners. That’s because we designed PhotoPost from the beginning to integrate efficiently with a website’s existing vBulletin forum, offering users one integrated login and registration instead of two, stylesheet integration, and other enhancements. But what PhotoPost does well for vBulletin owners, it does equally well for those that wish to integrate a gallery with many other forum types, or to simply add a photo gallery to their website with no forum at all. ”

 

 

 

(2) Vulnerability Details:

PhotoPost PHP web application has a computer security problem. Hackers can exploit it by XSS cyber 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. PhotoPost PHP has patched some of them. CXSECurity is a huge collection of information on data communications safety. Its main objective is to inform about errors in various applications. It also publishes suggestions, advisories, solutions details related to XSS vulnerabilities and cyber intelligence recommendations.

 

 

(2.1) The code flaw occurs at “|utmcct” parameter in “__utmz” Cookie.

For example, if a victim clicks the link below.

http://localhost/gallery/showphoto.php/photo/846/sort/'”><marquee><h1>test</h1></marquee><svg/onload=prompt(/tetraph/)&gt;

The content of “__utmz” cookie will be the following:

__utma 194200300.1295483682.1438243020.1438243020.1438245659.2

__utmc 194200300

__utmz 194200300.1438243020.1.1.utmccn=(referral)|utmcsr=mgs-on-track.com|utmcct=/gallery/showphoto.php/photo/846/sort/1%27%22%3E%3Cimg%20src=x%20onerror=alert%28%27tetraph%27%29%3E%3Cmarquee%3E%3Ch1%3Etest%3C/h1%3E%3C/marquee%3E|utmcmd=referral

__qca P0-814178849-1438243024810

__utmb 194200300

bbsessionhash 1683dd3bd3edffbd8383db382f025eba

bblastvisit 1438246612

So the malicious code can work in the user’s browser for long time.

 

 

(2.2) Forum Integrations

“PhotoPost can optionally integrate as an add-on to an existing forum on your site, and we do this extremely well. PhotoPost is a perfect fit with a forum, because sharing and discussing photos within PhotoPost comes naturally for a forum community.

With our forum integration, your users will use their existing forum account to login to PhotoPost, without needing to register again and maintain a separate account. Additionally, we offer stylesheet integrations with several forums to easily setup your PhotoPost gallery to match your forum’s look and feel, and with vBulletin 3.x we offer several additional enhancements.”

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.

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.

fc2.comのAlexaのランクはそれがtoppest日本のローカルウェブサイトの流通サービスである2月18日2015年52あります。

 

 

 

(1)脆弱性の説明:

FC2オンラインWebサービスは、コンピュータのサイバーセキュリティバグの問題があります。それは、オープンリダイレクト(未検証のリダイレクトとフォワード)攻撃によって悪用される可能性があります。ここでオープンリダイレクトの説明は次のとおりです。「オープンリダイレクトがパラメータを受け取り、何の検証も行わずにパラメータ値にユーザーをリダイレクトするアプリケーションです。この脆弱性は、それを実現することなく、悪質なサイトを訪問するユーザーを取得するためにフィッシング攻撃で使用されています。。 “それの一つの結果はフィッシングで​​す。 (OWASP)

 

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。

(1) Vulnerability description:

FC2 has a computer cyber security bug problem. It is vulnerable to XSS attacks. 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 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 programming code flaw occurs at fc2 URLs’ filenames . Fc2 only filter part of the filenames in the urls. Almost all urls are affected under domain blog.fc2.com/tag are affected. i.e.

(Canada). The company has investments in Pinterest, Ozon.ru, AHA Life, and Daily Grommet.” (Wikipedia)

 

The Alexa rank of rakuten.co.jp is 64 on May 29 2015. It is the second toppest Japanese local sevice website.




(1) Vulnerability Description:

Rakuten online website 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: “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)

 

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.

 

Since know only a little Japanese, not sure whether Rakuten pays much attention to Open Redirect Vulnerabilities or not. These bugs were found by using URFDS.

(1)脆弱性の説明:

楽天のオンラインウェブサイトは、コンピュータのサイバーセキュリティバグの問題があります。それは、オープンリダイレクト(未検証のリダイレクトとフォワード)攻撃によって悪用される可能性があります。ここでオープンリダイレクトの説明は次のとおりです。「Webアプリケーションは外部サイトへのリンクを指定するユーザ制御入力を受け付け、リダイレクトでそのリンクを使用しています。これは、フィッシング攻撃を簡素化HTTPパラメータがURL値が含まれており、可能性があります。。指定されたURLに要求をリダイレクトするようにWebアプリケーションを引き起こす。悪質なサイトへのURLの値を変更することにより、攻撃者がフィッシング詐欺を起動し、ユーザーの資格情報を盗むことができる。変更されたリンク内のサーバー名が、元のサイトと同じであるため、フィッシングの試みは、より信頼性の高い外観を持っています。」 (CWEから)

 

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。
