(2) Vulnerability Details:

6kbbs web application has a computer cyber security bug problem. It can be exploited by CSRF (Cross-Site Request Forgery) attacks. This may allow an attacker to trick the victim into clicking on the image to take advantage of the trust relationship between the authenticated victim and the application. Such an attack could trick the victim into creating files that may then be called via a separate CSRF attack or possibly other means, and executed in the context of their session with the application, without further prompting or verification.

Several 6kbbs products 0-day vulnerabilities have been found by some other bug hunter researchers before. 6kbbs has patched some of them. Open Sourced Vulnerability Database (OSVDB) is an independent and open-sourced database. The goal of the project is to provide accurate, detailed, current, and unbiased technical information on security vulnerabilities. The project promotes greater, open collaboration between companies and individuals. It has published suggestions, advisories, solutions details related to csrf 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)

About Group (about.com) All Topics (At least 99.88% links) Vulnerable to XSS & Iframe Injection Security Attacks, About.com Open Redirect Web Security Vulnerabilities

Man Running in Digital Vortex --- Image by © Michael Agliolo/Corbis

About Group (about.com) All Topics (At least 99.88% links) Vulnerable to XSS & Iframe Injection Security Attacks, About.com Open Redirect Security Vulnerabilities

 

Vulnerability Description:
About.com all “topic sites” are vulnerable to XSS (Cross-Site Scripting) and Iframe Injection (Cross Frame Scripting) attacks. This means all sub-domains of about.com are affected. Based on a self-written program, 94357 links were tested. Only 118 links do not belong to the topics (Metasites) links. Meanwhile, some about.com main pages are vulnerable to XSS attack, too. This means no more than 0.125% links are not affected. At least 99.875% links of About Group are vulnerable to XSS and Iframe Injection attacks. In fact, for about.com’s structure, the main domain is something just like a cover. So, very few links belong to them.

 

Simultaneously, the About.com main page’s search field is vulnerable to XSS attacks, too. This means all domains related to about.com are vulnerable to XSS attacks.

 

 

Simultaneously, the About.com main page’s search field is vulnerable to XSS attacks, too. This means all domains related to about.com are vulnerable to XSS attacks.

 

For the Iframe Injection vulnerability. They can be used to do DDOS (Distributed Denial-of-Service Attack) to other websites, too.

Here is one example of DDOS based on Iframe Injection attacks of others.
http://www.incapsula.com/blog/world-largest-site-xss-ddos-zombies.html

 

In the last, some “Open Redirect” vulnerabilities related to about.com are introduced. There may be large number of other Open Redirect Vulnerabilities not detected. Since About.com are trusted by some the other websites. Those vulnerabilities can be used to do “Covert Redirect” to these websites.

 

 

Vulnerability Disclosure:
Those vulnerabilities were reported to About on Sunday, Oct 19, 2014. No one replied. Until now, they are still unpatched.

(1) Some Basic Background

 

“For March 2014, 61,428,000 unique visitors were registered by comScore for About.com, making it the 16th-most-visited online property for that month.” (The New York Times)

 

“About.com, also known as The About Group (formerly About Inc.), is an Internet-based network of content that publishes articles and videos about various subjects on its “topic sites,” of which there are nearly 1,000. The website competes with other online resource sites and encyclopedias, including those of the Wikimedia Foundation, and, for March 2014, 61,428,000 unique visitors were registered by comScore for About.com, making it the 16th-most-visited online property for that month. As of August 2012, About.com is the property of IAC, owner of Ask.com and numerous other online brands, and its revenue is generated by advertising.” (Wikipedia)

 

“As of May 2013, About.com was receiving about 84 million unique monthly visitors.” (TechCrunch. AOL Inc.)

 

“According to About’s online media kit, nearly 1,000 “Experts” (freelance writers) contribute to the site by writing on various topics, including healthcare and travel.” (About.com)

 

 

(1.2) Topics Related to About.com
“The Revolutionary About.com Directory and Community Metasite. Hundreds of real live passionate Guides covering Arts, Entertainment, Business, Industry, Science, Technology, Culture, Health, Fitness, Games,Travel, News, Careers, Jobs, Sports, Recreation, Parenting, Kids, Teens, Moms, Education, Computers, Hobbies and Local Information.” (azlist.about.com)

In fact, those are not all topics of about.com. Some of the topics are not listed here such as,
http://specialchildren.about.com

 

So, there are more than 1000 topics related to about.com.

 

 

(1.3) Result of Exploiting XSS Attacks
XSS 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.

 

Base on Acunetix, exploited XSS is commonly used to achieve the following malicious results:

“Identity theft

Accessing sensitive or restricted information

Gaining free access to otherwise paid for content

Spying on user’s web browsing habits

Altering browser functionality

Public defamation of an individual or corporation

Web application defacement

Denial of Service attacks (DOS)

” (Acunetix)

 

 

(1.4) Basics of Iframe Injection (Cross-frame-Scripting) Vulnerabilities
“In an XFS (Cross-frame-Scripting) attack, the attacker exploits a specific cross-frame-scripting bug in a web browser to access private data on a third-party website. The attacker induces the browser user to navigate to a web page the attacker controls; the attacker’s page loads a third-party page in an HTML frame; and then JavaScript executing in the attacker’s page steals data from the third-party page.” (OWASP)

 

“XFS also sometimes is used to describe an XSS attack which uses an HTML frame in the attack. For example, an attacker might exploit a Cross Site Scripting Flaw to inject a frame into a third-party web page; or an attacker might create a page which uses a frame to load a third-party page with an XSS flaw.” (OWASP)

 

 

(1.5) Basic of Open Redirect (Dest Redirect Privilege Escalation) Vulnerabilities
“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.” (OWASP)

Open redirect is listed in OWASP top 10. The general consensus of it is “avoiding such flaws is extremely important, as they are a favorite target of phishers trying to gain the user’s trust.”

 

Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. CNN 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 following web securities have been published here, Injection, Broken Authentication and Session Management, Cross-Site Scripting (XSS), Insecure Direct Object References, Security Misconfiguration, Sensitive Data Exposure, Missing Function Level Access Control, Cross-Site Request Forgery (CSRF), Using Components with Known Vulnerabilities, Unvalidated Redirects and Forwards. It also publishes suggestions, advisories, solutions details related to XSS and URL Redirection vulnerabilities and cyber intelligence recommendations.

(5) About (about.com) Open Redirect Multiple (Dest Redirect Privilege Escalation) Security Vulnerabilities

About Group online web application has a computer cyber security bug problem. It can be exploited by Unvalidated Redirects and Forwards (URL Redirection) attacks. This could allow a user to create a specially crafted URL, that if clicked, would redirect a victim from the intended legitimate web site to an arbitrary web site of the attacker’s choosing. Such attacks are useful as the crafted URL initially appear to be a web page of a trusted site. This could be leveraged to direct an unsuspecting user to a web page containing attacks that target client side software such as a web browser or document rendering programs.

 

The vulnerabilities can be attacked without user login. Tests were performed on Microsoft IE (10.0.9200.16750) of Windows 8, Mozilla Firefox (34.0) & Google Chromium 39.0.2171.65-0 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (14.04),Apple Safari 6.1.6 of Mac OS X Lion 10.7.

Vendor legal intimidation and censorship attempts are not tolerated here!” All the fllowing web securities have been published here, Injection, Broken Authentication and Session Management, Cross-Site Scripting (XSS), Insecure Direct Object References, Security Misconfiguration, Sensitive Data Exposure, Missing Function Level Access Control, Cross-Site Request Forgery (CSRF), Using Components with Known Vulnerabilities, Unvalidated Redirects and Forwards.

 

 

(4) Alibaba Taobao(taobao.com)Covert Redirect Security Vulnerability Based on Apple.com



(4.1) Vulnerability description:

Alibaba Taobao has a security problem. It can be exploited by Covert Redirect attacks. Taobao will check whether the redirected URL belongs to domains in Taobao’s whitelist, e.g.

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 Taobao 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 Taobao directly.

In fact, Apple.com was found can be exploited by Open Redirect vulnerabilities. Those vulnerabilities details will be published in the near future.



(4.2) The vulnerability occurs at “redirect.htm?” page, with parameter “&url”, i.e.

The vulnerabilities can be attacked without user login. Tests were performed on IE (10.0) of Windows 8, Firefox (34.0) & Google Chromium 39.0.2171.65-0 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (14.04),Safari 6.1.6 of Mac OS X Lion 10.7.

 

 

(4.3) Use a website for the tests,the redirected webpage is “http://www.tetraph.com/blog“. Just suppose it is malicious.

एक अन्य Heartbleed?वेब सुरक्षा में पाया दोषों, Covert Redirect

इंटरनेट अब भी Heartbleed बग से जूझ रहा है, जबकि सुरक्षा प्रोटोकॉल OAuth 2.0 और OpenID में एक प्रमुख नए भेद्यता खोज की गई है.

सिंगापुर में नानयांग प्रौद्योगिकी विश्वविद्यालय की पीएचडी की छात्रा वांग जिंग हैकर्स उपयोगकर्ताओं को जानने के बिना प्रवेश जानकारी चोरी करने की कोशिश में फ़िशिंग तकनीक का उपयोग करने की अनुमति देता है कि एक बग देखा.

बग अनिवार्य रूप से साइबर अपराधी के बजाय डोमेन faking के अधिक आम रणनीति का एक फ़िशिंग पॉपअप सत्ता में असली वेबसाइट प्रमाणीकरण का उपयोग करने की अनुमति देता है.इस प्रक्रिया में, हैकर्स उपयोगकर्ता के लॉगिन क्रेडेंशियल प्राप्त होगा.

Xuất hiện lỗ hổng Covert Redirect, bản sao của “Trái tim rỉ máu”

Xuất hiện lỗ hổng Covert Redirect, bản sao của “Trái tim rỉ máu”

Một nghiên cứu sinh tại trường Đại học Công nghệ Nanyang (Singapore) vừa phát hiện một lỗ hổng bảo mật tồn tại trong phần mềm mã nguồn mở đang được rất nhiều website sử dụng. Thông tin mới nhất cho thấy lỗ hổng này ảnh hưởng đến cả Google, Facebook, Microsoft, LinkedIn, PayPal và một số công ty lớn khác.

Website Security

Wang Jing, nghiên cứu sinh tiến sĩ tại Đại học Công nghệ Nanyang là người phát hiện ra lỗ hổng đang tồn tại trong công cụ đăng nhập mã nguồn mở OAuth và OpenID. Wang Jing gọi lỗ hổng này là “Covert Redirect” (tạm dịch là Bí mật chuyển hướng). Hacker có thể gài mã độc ẩn dưới dạng một cửa sổ pop-up, hiện ra khi người dùng đăng nhập vào một website có lỗ hổng. Chẳng hạn như khi người dùng gõ địa chỉ Facebook, một cửa sổ pop-up hiện ra yêu cầu điền tên đăng nhập và mật khẩu. Nếu người dùng đưa thông tin vào thì những thông tin ấy sẽ “bí mật chuyển hướng” đến hacker.

하트블리드 이어 ‘오픈ID’와 ‘오쓰(OAuth)’서도 심각한 보안 결함

covert_redirect1


‘하트블리드(Heartbleed)’ 버그에 이어 가입자 인증 및 보안용 오픈소스 SW인 ‘오픈ID’와‘오쓰(OAuth)’에도 심각한 결함이 발견됐다고 씨넷, 벤처비트 등 매체들이 보도했다.

 

싱 가폴난양대학교에 재학중인 ‘왕 징(Wang Jing)’ 박사는 수 많은 웹사이트와 구글, 페이스북, 링크드인, MS, 페이팔 등에서 사용하고 있는 로그인 툴인 ‘OAuth’와‘오픈ID’에 치명적인 결함이 발견됐다고 밝혔다. ‘코버트리디렉트(Covert Redirect)’라고 일컬어지는 이 결함은 감염된 도메인의 로그인 팝업을 통해 해킹이 이뤄진다.

 

가 령 인터넷 사용자들이 악의적인 피싱 사이트를 클릭하면 가입자 인증을 위해 페이스북 팝업 윈도가 뜨는데 가입자를 속이 기위해 가짜 도메인 이름을 사용하는 것이 아니라 진짜 사이트의 도메인을 활용한다고 한다. 만일 가입자가 로그인을 하면 합법적인 사이트가 아니라 피싱사이트로 e메일 주소, 생일, 연락처 등 개인 정보들이 흘러들어간다.

 

왕 은 페이스북 등 업체에 이 같은 결함을 알렸으며 페이스북은 결함이 OAuth 2.0가 연관된 것으로 인식하고 있지만 짧은 시간내 해결될 수는 없을 것이란 답을 얻은 것으로 알려졌다. 왕은 이번 결함이 구글, 링크드인, 마이크로소프트, 페이스북, 페이팔 등 다수의 오픈ID와 OAuth를 활용하는 기업들이 영향을 받을 것으로 예상했다.

 

왕 은 “제3의 애플리케이션 개발자들이 화이트리스트를 엄격하게 적용하면 해커 공격의 빌미를 제공하지 않을 것”이라고 말했다. 하지만 “실제로 많은 애플리케이션 개발자들이 여러가지 이유로 이런 조치를 취하지않고 있다는 게 OAuth 2.0과 오픈ID의 결함 문제를 심각하게 만들고 있다”고 덧붙였다.
