Maxwell’s Formulation – Differential Forms on Euclidean Space

Maxwell’s Formulation – Differential Forms on Euclidean Space

Author: Jing Wang

Institute: School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore

 

maxwell

 

One of the greatest advances in theoretical physics of the nineteenth century was Maxwell’s formulation of the the equations of electromagnetism. This article uses differential forms to solve a problem related to Maxwell’s formulation. The notion of differential form encompasses such ideas as elements of surface area and volume elements, the work exerted by a force, the flow of a fluid, and the curvature of a surface, space or hyperspace. An important operation on differential forms is exterior differentiation, which generalizes the operators div, grad, curl of vector calculus. the study of differential forms, which was initiated by E.Cartan in the years around 1900, is often termed the exterior differential calculus.However, Maxwell’s equations have many very important implications in the life of a modern person, so much so that people use devices that function off the principles in Maxwell’s equations every day without even knowing it.

Yahoo Yahoo.com Yahoo.co.jp Open Redirect (Unvalidated Redirects and Forwards) Web Security Bugs

 

Though Yahoo lists open redirect vulnerability on its bug bounty program. However, it seems Yahoo do not take this vulnerability seriously at all.

 

Multiple Open Redirect vulnerabilities were reported Yahoo. All Yahoo’s responses were “It is working as designed”. However, these vulnerabilities were patched later.

 

Several other security researcher complained about getting similar treatment, too.
http://seclists.org/fulldisclosure/2014/Jan/51
http://seclists.org/fulldisclosure/2014/Feb/119

 

All Open Redirect Vulnerabilities are intended behavior? If so, why patch them later?

yahoo_wont_fix_meitu_1

 


From report of CNET, Yahoo’s users were attacked by redirection vulnerabilities. “Yahoo.com visitors over the last few days may have been served with malware via the Yahoo ad network, according to Fox IT, a security firm in the Netherlands. Users visiting pages with the malicious ads were redirected to sites armed with code that exploits vulnerabilities in Java and installs a variety of different malware. ”
http://www.cnet.com/news/yahoo-users-exposed-to-malware-attack/

 

Moreover, since Yahoo is well-known worldwide. these vulnerabilities can be used to attack other companies such as Google, eBay, The New York Times, Amazon, Godaddy, Alibaba, Netease, e.g. by bypassing their Open Redirect filters (Covert Redirect). These cyber security bug problems have not been patched. Other similar web and computer flaws will be published in the near future.

 

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.

Both Yahoo and Yahoo Japan 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.

Alle Links zu New York Times Artikel Vor 2013 anfällig für XSS-Angriffe

Alle Links zu New York Times Artikel Vor 2013 anfällig für XSS-Angriffe

 

URLs, um Artikel in der New York Times (NYT) vor 2013 veröffentlicht wurden gefunden anfällig für einen XSS (Cross-Site Scripting) Angriff der Lage ist, Code im Kontext des Web-Browsers ausgeführt werden zu können.

 

thedhruvsoni_1372883880_65


Basierend auf nytimes die Gestaltung, fast alle URLs vor 2013 sind betroffen (Alle Seiten von Artikeln). In der Tat, alle Artikel Seiten, die Schaltfläche “Drucken”, “Jede Seite” Taste enthalten, werden “Seite *” Taste “NEXT PAGE” -Taste beeinflusst.

 

Nytimes geändert diesen Mechanismus seit 2013. Es decodiert die URLs, seine Server gesendet. Dadurch ist der Mechanismus nun viel sicherer.

 

Jedoch werden alle URLs vor 2013 immer noch mit dem alten Mechanismus. Das bedeutet fast allen Artikelseiten vor 2013 sind immer noch anfällig für XSS-Angriffe. Ich denke, der Grund, nytimes keine URLs filtern, bevor die Kosten. Es kostet zu viel (Geld und Humankapital), um in der Datenbank nach Artikel gepostet, bevor ändern.

 

Die Sicherheitslücke wurde von einem Mathematik Doktorand Wang Jing von der Schule für Physikalische und Mathematische Wissenschaften (SPMS), Nanyang Technological University, Singapur.

 

POC und Blog Erklärung von Wang gegeben,
https://www.youtube.com/watch?v=RekCK5tjXWQ
http://tetraph.com/security/xss-vulnerability/new-york-times-nytimes-com-page-design-xss-vulnerability-almost-all-article-pages-are-affected/

 

Unterdessen sagte Wang: “Die New York Times hat einen neuen Mechanismus jetzt angenommen. Dies ist eine bessere Schutzmechanismus.”

 

 

Auch wenn die Artikel sind alt, sind die Seiten noch relevant
Ein Angriff auf neueren Artikel würde auf jeden Fall haben erhebliche Auswirkungen gehabt, aber Artikeln von 2012 oder sogar noch älter sind alles andere als überholt. Es wäre immer noch im Rahmen eines Angriffs von Bedeutung sein.

 

Cyberkriminelle können verschiedene Möglichkeiten, um den Link, um potenzielle Opfer zu senden und aufzuzeichnen hohen Erfolgsraten, alle mit mehr gezielte Angriffe zu entwickeln.

 

 

Was ist XSS?
Cross-Site Scripting (XSS) ist eine Art von Computer-Sicherheitslücke in der Regel in Web-Anwendungen gefunden. XSS ermöglicht es Angreifern, clientseitige Skript in Webseiten, die von anderen Benutzern eingesehen zu injizieren. Eine Cross-Site-Scripting-Schwachstelle kann von Angreifern wie der Same Origin Policy verwendet werden, um Zugangskontrollen zu umgehen. Cross-Site Scripting auf Webseiten durchgeführt entfielen rund 84% aller Sicherheitslücken von Symantec ab 2007 dokumentiert (Wikipedia)

 

 

 

 

Weather Channel Website Vulnerable to Reflected XSS Attacks

cloud_computing_coding_security_lock_thinkstock_466683417-100412455-primary.idge
 

Popular Weather Channel web site (Weather.com) has been found to be vulnerable to a reflected Cross-Site Scripting flaw, according to security researcher Wang Jing’s research. The vulnerability lies in that Weather.com does not filter malicious script codes when constructing HTML tags with its URLs. This way, an attacker just adds a malicious script at the end of the URL and executes it.

“If The Weather Channel’s users were exploited, their Identity may be stolen,” Jing said via email. “At the same time, attackers may use the vulnerability to spy users’ habits, access sensitive information, alter browser functionality, perform denial of service attacks, etc.”

Wang Jing is a Ph.D student from School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore. He found that at list 76.3% of Weather Channel website links were vulnerable to XSS attacks. Attackers just need to add scripts at end of Weather Channel’s URLs. Then the scripts will be executed.

New York Times Articles Before 2013 May Vulnerable to XSS Attack

Information pinned on noticeboard

New York Times articles’ pages dated before 2013 may suffer from an XSS (Cross-site Scripting) vulnerability, according to the report posted by security researcher Wang Jing. Wang is a mathematics Ph.D student from School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore. He published his discovery in well-known security mail list Full Disclosure.

 

According to Wang, all pages before 2013 that contain buttons such as “PRINT”,”SINGLE PAGE”, “Page” and “NEXT PAGE” are affected by the XSS vulnerability. Meanwhile, the researcher also published a proof of concept video to prove the existence of the XSS flaw.

 

As of yet, there are no known cases of criminals exploiting the Times’ XSS issue in order to attack users. However, according to Wang, the threat is possible, and the New York Times has a big enough audience that an XSS attack, even via its older articles, could still affect a broad number of users. The affected New York Times articles are still indexed in Google search engines, and are still frequently hyperlinked in other articles.

 

However according to the researcher, New York Times has now a much safer mechanism, implemented sometime in 2013, that sanitizes all URLs sent to its server.

 

Cross-site scripting (XSS) vulnerabilities usually reside in web applications and can be used by attackers to modify the normal flow of the web page. A cybercriminal can use it easily to perform URL redirect, mine for victim’s browser details, session hijacking, phishing, or even steal cookies.

 

XSS issues are not entirely uncommon. So far we have seen that Google, Amazon, Microsoft, Yahoo and Facebook all had this kind issue reported.

Google DoubleClick.net (Advertising) System URL Redirection Vulnerabilities Could Be Used by Spammers

 

Although Google does not include Open Redirect vulnerabilities in its bug bounty program, its preventive measures against Open Redirect attacks have been quite thorough and effective to date.

 

However, Google might have overlooked the security of its DoubleClick.net ​advertising system. After some test, it is found that most of the redirection URLs within DoubleClick.net are vulnerable to Open Redirect vulnerabilities. Many redirection are likely to be affected. 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.

 

These redirections can be easily used by spammers, too.

 

Some URLs belong to Googleads.g.Doubleclick.net are vulnerable to Open Redirect attacks, too. While Google prevents similar URL redirections other than Googleads.g.Doubleclick.net. Attackers can use URLs related to Google Account to make the attacks more powerful.

 

Moreover, these vulnerabilities can be used to attack other companies such as Google, eBay, The New York Times, Amazon, Godaddy, Yahoo, Netease, e.g. by bypassing their Open Redirect filters (Covert Redirect). These cyber security security bug problems have not been patched. Other similar web and computer attacks will be published in the near future.

(3.1) Google Covert Redirect Vulnerability Based on Googleads.g.doubleclick.net

Domain:
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. Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University. Together they own about 14 percent of its shares but control 56 percent of the stockholder voting power through supervoting stock. They incorporated Google as a privately held company on September 4, 1998. An initial public offering followed on August 19, 2004. Its mission statement from the outset was “to organize the world’s information and make it universally accessible and useful,” and its unofficial slogan was “Don’t be evil”. In 2004, Google moved to its new headquarters in Mountain View, California, nicknamed the Googleplex. 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)

Sicherheitslücke in OAuth 2.0 und OpenID gefunden

covert_redirect3

Wang Jing, Student an der Nanyang Technological University in Singapur, hat nach dem Bekanntwerden des OpenSSL-Heartbleed-Lecks, eine weitere schwere Sicherheitslücke entdeckt, diesmal in den Authentifizierungsmethoden OAuth 2.0 und OpenID. Die als “Covert Redirect” (“Heimliche Umleitung”) benannte Sicherheitslücke ermöglicht es Angreifern, dem Nutzer einen echt aussehenden Login-Screen unterzujubeln und sich so Zugriff auf die bereitgestellten Daten zu verschaffen. Das gefährliche daran: Die Sicherheitslücke besitzt – anders als bisher bekannte Fishing-Versuche – eine legitime Domainadresse, kann also über einen Blick in die URL-Zeile des Browsers nicht oder nur sehr schwer entlarvt werden. Auf OAuth 2.0 und OpenID bieten inzwischen zahlreiche Webdienste um einen direkten Login in andere Dienste und Apps zu ermöglichen, darunter auch Google, Facebook, Microsoft und Co.

 

So ist es möglich, dem Nutzer eine Mail mit einem speziell präparierten Link zukommen zu lassen, ein Klick auf diesen öffnet eben wie gesagt eine legitime Adresse samt entsprechendem Logo. Autorisiert der Nutzer dann diese Anfrage und loggt sich in den Dienst ein, so werden die Daten nicht an die vermeintliche App weitergeleitet, sondern gelangen eben in den Besitz des Angreifers. Je nachdem, welche Daten abfragt werden, bekommt dieser somit also E-Mail-Adresse, Geburtsdatum, Kontaktlisten und dergleichen. Ebenso ist es möglich, den Nutzer nach dem Login auf eine beliebige Webseite, welche unter Umständen Malware verbreitet, weiterzuleiten.

covert-redirect-12


Die Lösung des Problems könnte aber – wenn es überhaupt einmal eine geben sollte – eine langwierige Sache sein. Wang Jing hat bereits etliche größere Anbieter der Loginmethoden angeschrieben und über die gefundene Sicherheitslücke aufgeklärt, hierbei gab es jedoch unterschiedliche Aussagen. Im Hause Google beobachtet man das Problem, Microsoft ist sich keiner Schuld bewusst und schiebt die Sicherheitslücke an Drittanbieter ab. Lediglich Facebook scheint hier ehrlich zu sein und gibt an, dass es sich dabei um ein grundsätzliches Problem von OAuth 2.0 und OpenID handelt – möchte man nicht eine umfangreiche Whitelist mit sämtlichen nicht-schädlichen Apps pflegen, ist die Sicherheitslücke nicht “mal eben so” zu beheben. Im Grunde dürften sich sämtliche Gegenmaßnahmen negativ auf die Nutzererfahrung auswirken, was natürlich keiner der Dienste in Kauf nehmen möchte – und so bleibt es hierbei scheinbar beim “kleineren Übel” für die Anbieter.

So bleibt eigentlich nur die Möglichkeit, auf OAuth 2.0 oder OpenID als Login-Methode für Drittanbieter Dienste und Apps zu verzichten oder genauestens darauf zu achten, auf was man klickt. Hat man keine explizite Autorisierung angestoßen, sollte man die geöffneten Tabs umgehend schließen und darauf hoffen, dass sich nicht doch irgendwo ein falscher Link eingepfercht hat.
