Skins, wrappers & master page templates can be applied globally to all forums or to any specific forum.”

 

 

(2) Vulnerability Details:

InstantForum.NET web application has a cyber security bug problem. It can be exploited by stored XSS 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. InstantForum has patched some of them. BugScan is the first community-based scanner, experienced five code refactoring. It has redefined the concept of the scanner provides sources for the latest info-sec news, tools, and advisories. It also publishs suggestions, advisories, cyber intelligence, attack defense and solutions details related to important vulnerabilities.

 

(2.1) The first programming code flaw occurs at “&SessionID” parameter in “Join.aspx?” page.


(2.2) The second programming code flaw occurs at “&SessionID” parameter in “Logon.aspx?” page.

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

<span style=”font-size: medium;”><strong>Alle Links zu New York Times Artikel Vor 2013 anfällig für XSS-Angriffe</strong>
</span>

&nbsp;

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.

&nbsp;

<span style=”font-size: medium;”><a href=”https://computertechhut.files.wordpress.com/2015/05/thedhruvsoni_1372883880_65.jpg”><img class=”alignnone  wp-image-154″ src=”https://computertechhut.files.wordpress.com/2015/05/thedhruvsoni_1372883880_65.jpg?w=300&#8243; alt=”thedhruvsoni_1372883880_65″ width=”601″ height=”451″ /></a>
</span>

<span style=”font-size: medium;”>
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.</span>

&nbsp;

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

&nbsp;

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.

&nbsp;

Die Sicherheitslücke wurde von einem Mathematik Doktorand <a href=”http://tetraph.com/wangjing”>Wang Jing</a> von der Schule für Physikalische und Mathematische Wissenschaften (SPMS), Nanyang Technological University, Singapur.

&nbsp;

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

&nbsp;

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

&nbsp;

&nbsp;

<strong>Auch wenn die Artikel sind alt, sind die Seiten noch relevant</strong>
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.

&nbsp;

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

&nbsp;

&nbsp;

<strong>Was ist XSS?</strong>
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)

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.

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.
