(2) Vulnerability Details:

SITEFACT web application has a computer cyber security bug problem. It can be exploited by 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. SITEFACT 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! It also publishes suggestions, advisories, solutions details related to XSS vulnerabilities and cyber intelligence recommendations.

 

(2.1) The first programming flaw occurs at “/index.cfm?" page with “&res" “&skt" “&pid" parameters.

 

(2.2) The second programming flaw occurs at login domain “/index.cfm?" page with “&sid" parameter.

(2) Vulnerability Details:

Webshop hun web application has a computer security bug problem. It can be exploited by Directory Traversal – Local File Include (LFI) attacks. A local file inclusion (LFI) flaw is due to the script not properly sanitizing user input, specifically path traversal style attacks (e.g. ‘../../’) supplied to the parameters. With a specially crafted request, a remote attacker can include arbitrary files from the targeted host or from a remote host . This may allow disclosing file contents or executing files like PHP scripts. Such attacks are limited due to the script only calling files already on the target host.

Several similar products vulnerabilities have been found by some other bug hunter researchers before. Webshop hun has patched some of them. The MITRE Corporation is a not-for-profit company that operates multiple federally funded research and development centers (FFRDCs), which provide innovative, practical solutions for some of our nation’s most critical challenges in defense and intelligence, aviation, civil systems, homeland security, the judiciary, healthcare, and cybersecurity. It has published suggestions, advisories, solutions details related to website vulnerabilities.

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.

(1.3) 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.

Falha de segurança afeta logins de Facebook, Google e Microsoft

covert_redirect3

Um estudante de PHD de Singapura, Wang Jing, identificou a falha, chamada de “Covert Redirect”, que consegue usar domínios reais de sites para verificação de páginas de login falsas, enganando os internautas.

 

Os cibercriminosos podem criar links maliciosos para abrir janelas pop-up do Facebook pedindo que o tal aplicativo seja autorizado. Caso seja realizada esta sincronização, os dados pessoais dos usuários serão passados para os hackers.

 

Wang afirma que já entrou em contato com o Facebook, porém recebeu uma resposta de que “entende os riscos de estar associado ao OAuth 2.0″ e que corrigir a falha “é algo que não pode ser feito por enquanto”.

 

O Google afirmou que o problema está sendo rastreado, o LinkedIn publicou nota em que garante que já tomou medidas para evitar que a falha seja explorada, e a Microsoft negou que houvesse vulnerabilidade em suas páginas, apenas nas de terceiros.

 

A recomendação do descobridor da falha para os internautas é que evitem fazer o login com dados de confirmação de Facebook, Google ou qualquer outro serviço sem terem total certeza de que estão em um ambiente seguro.

 

 

Especialistas: erro é difícil de corrigir

O site CNET ouviu dois especialistas em segurança virtual sobre o assunto. Segundo Jeremiah Grossman, fundador e CEO interino da WhiteHat Security, afirma que a falha “não é fácil de corrigir”. Segundo Chris Wysopal, diretor da Veracode, a falha pode enganar muita gente.

 

“A confiança que os usuários dão ao Facebook e outros serviços que usam OAuth pode tornar mais fácil para os hackers enganarem as pessoas para que elas acabem dando suas informações pessoais a ele”, afirma Wsyopal.
