Caution Details:



(1) Vendor & Product Description:



Vendor:

Winmail Server




Product & Vulnerable Versions:

Winmail Server

4.2   4.1




Vendor URL & Download:

Product can be obtained from here,






Product Introduction Overview:

"Winmail Server is an enterprise class mail server software system offering a robust feature set, including extensive security measures. Winmail Server supports SMTP, POP3, IMAP, Webmail, LDAP, multiple domains, SMTP authentication, spam protection, anti-virus protection, SSL security, Network Storage, remote access, Web-based administration, and a wide array of standard email options such as filtering, signatures, real-time monitoring, archiving, and public email folders. Winmail Server can be configured as a mail server or gateway for ISDN, ADSL, FTTB and cable modem networks, beyond standard LAN and Internet mail server configurations."









(2) Vulnerability Details:

Winmail Server web application has a computer security problem. Hackers can exploit it by reflected 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. Winmail Server has patched some of them. "scip AG was founded in 2002. We are driven by innovation, sustainability, transparency, and enjoyment of our work. We are completely self-funded and are thus in the comfortable position to provide completely independent and neutral services. Our staff consists of highly specialized experts who focus on the topic information security and continuously further their expertise through advanced training". Scip has recorded similar XSS bugs, such as scipID 26980.




(2.1) The code flaw occurs at "&lid" parameter in "badlogin.php" page. In fact, CVE-2005-3692 mentions that "&retid" parameter in "badlogin.php" page is vulnerable to XSS attacks. But it does not mention "&lid" parameter". The scipID of the bug is 26980. Bugtraq (SecurityFocus) ID is 15493. OSVDB ID is 20926.

Amazon Covert Redirect Bug Based on Kindle Daily Post, Omnivoracious, Car Lust

Amazon Covert Redirect Bug Based on Kindle Daily Post, Omnivoracious, Car Lust

-- Amazon Covert Redirect Based on Kindle Daily Post, Omnivoracious, Car Lust & kindlepost.com, omnivoracious.com, carlustblog.com Open Redirect Web Security Vulnerabilities





Domains:
http://www.amazon.com

"Amazon.com, Inc. (/ˈæməzɒn/ or /ˈæməzən/) is an American electronic commerce company with headquarters in Seattle, Washington. It is the largest Internet-based retailer in the United States. Amazon.com started as an online bookstore, but soon diversified, selling DVDs, Blu-rays, CDs, video downloads/streaming, MP3 downloads/streaming, software, video games, electronics, apparel, furniture, food, toys and jewelry. The company also produces consumer electronics—notably, Amazon Kindle e-book readers, Fire tablets, Fire TV and Fire Phone — and is a major provider of cloud computing services. Amazon also sells certain low-end products like USB cables under its inhouse brand AmazonBasics. Amazon has separate retail websites for United States, United Kingdom & Ireland, France, Canada, Germany, The Netherlands, Italy, Spain, Australia, Brazil, Japan, China, India and Mexico. Amazon also offers international shipping to certain other countries for some of its products. In 2011, it had professed an intention to launch its websites in Poland and Sweden." (Wikipedia)





All kindlepost.com, omnivoracious.com, carlustblog.com are websites belonging to Amazon.

"Car Lust is, very simply, where interesting cars meet irrational emotion. It's a deeply personal exploration of the hidden gems of the automotive world; a twisted look into a car nut's mind; and a quirky look at the broader automotive universe - a broader universe that lies beneath the new, the flashy, and the trendy represented in the car magazines."

Vulnerabilities Description:
Amazon has a computer bug security problem. Both Amazon itself and its websites are vulnerable to different kind of attacks. This allows hackers to do phishing attacks to Amazon users.


When a user is redirected from amazon to another site, amazon will check a variable named "token". Every redirected website will be given one token. This idea is OK. However, all URLs related to the redirected website use the same token. This means if the authenticated site itself has Open Redirect vulnerabilities. Then victims can be redirected to any site from Amazon.


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.


Use a website for the following tests. The website is "http://www.diebiyi.com/articles". Suppose this website is malicious,

Rakuten Online Website Open Redirect (URL Redirection) Cyber Security Vulnerabilities


















Rakuten Online Website Open Redirect (URL Redirection) Cyber Security Vulnerabilities



Domain:
rakuten.com

"Rakuten, Inc. (楽天株式会社 Rakuten Kabushiki-gaisha?) is a Japanese electronic commerce and Internet company based in Tokyo, Japan. Its B2B2C e-commerce platform Rakuten Ichiba is the largest e-commerce site in Japan and among the world’s largest by sales. Hiroshi Mikitani founded the company in February 1997 as MDM, Inc., and is still its chief executive. Rakuten Shopping Mall (楽天市場 Rakuten Ichiba?) started operations in May 1997. In June 1999, the company changed its name to Rakuten, Inc. The Japanese word rakuten means optimism. In 2012, the company's revenues totaled US$4.6 billion with operating profits of about US$244 million. In June 2013, Rakuten, Inc. reported it had a total of 10,351 employees worldwide. In 2005, Rakuten started expanding outside Japan, mainly through acquisitions and joint ventures. Its acquisitions include Buy.com (now Rakuten.com Shopping in the US), Priceminister (France), Ikeda (now Rakuten Brasil), Tradoria (now Rakuten Deutschland), Play.com (UK), Wuaki.tv (Spain), and Kobo Inc. (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.





(2) Use one of webpages for the following tests. The webpage address is "http://itinfotech.tumblr.com/". Can suppose that this webpage is malicious.

rakuten.co.jpのAlexaのランクは、第2 toppest日本の地方流通サービスのウェブサイトである5月29日2015年64あります。




（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。

楽天リダイレクトの脆弱性かどうかを開くために多くの注意を払っているかどうかわからない、少しだけ日本語を知っているので。
