(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.

http://www.exlibrisgroup.org/display/CrossProductCC/PDS+OpenSSO+Integration

 

Product Description:

“NYU has integrated PDS with Sun’s OpenSSO Identity Management application. The PDS/OpenSSO integration uses PDS as the NYU Libraries’ single sign-on system and leverages NYU’s OpenSSO system to provide seamless interaction between library applications and university services. The integration merges patron information from OpenSSO (e.g. name, email, e-resources access) with patron information from Aleph (e.g. borrower status and type) to ensure access to the multitude of library services.”

“The NYU Libraries operate in a consortial environment in which not all users are in OpenSSO and not all OpenSSO users are in Aleph. PDS is hosted in an active/passive capacity on our Primo front-end servers. Due to the nature of PDS and Aleph, patrons are required to have an Aleph account in order to login to the library’s SSO environment. The exception to this rule is EZProxy.”

 

 

(2) Vulnerability Details:

NYU OpenSSO Integration has a security problem. It is vulnerable to Open Redirect Attacks.

Facebook Old Generated URLs Still Vulnerable to Open Redirect Attacks & A New Open Redirect Web Security Bugs




Domain:
http://www.facebook.com



“Facebook is an online social networking service headquartered in Menlo Park, California. Its website was launched on February 4, 2004, by Mark Zuckerberg with his college roommates and fellow Harvard University students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. The founders had initially limited the website’s membership to Harvard students, but later expanded it to colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities and later to high-school students. Since 2006, anyone who is at least 13 years old is allowed to become a registered user of the website, though the age requirement may be higher depending on applicable local laws. Its name comes from a colloquialism for the directory given to it by American universities students.” (Wikipedia)



“Facebook had over 1.44 billion monthly active users as of March 2015.Because of the large volume of data users submit to the service, Facebook has come under scrutiny for their privacy policies. Facebook, Inc. held its initial public offering in February 2012 and began selling stock to the public three months later, reaching an original peak market capitalization of $104 billion. As of February 2015 Facebook reached a market capitalization of $212 Billion.” (Wikipedia)

(1) General Vulnerabilities Description:

(1.1) Two Facebook vulnerabilities are introduced in this article.

Facebook has a computer cyber security bug problem. It can be exploited by Open Redirect 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.


Since Facebook is trusted by large numbers of other websites. Those vulnerabilities can be used to do “Covert Redirect” to other websites such as Amazon, eBay, Go-daddy, Yahoo, 163, Mail.ru etc.

 

(1.1.1)

One Facebook Open Redirect vulnerability was reported to Facebook. Facebook adopted a new mechanism to patch it. Though the reported URL redirection vulnerabilities are patched. However, all old generated URLs are still vulnerable to the attacks. Section (2) gives detail of it.

The reason may be related to Facebook’s third-party interaction system or database management system or both. Another reason may be related to Facebook’s design for different kind of browsers.

 

(1.1.2) Another new Open Redirect vulnerability related to Facebook is introduced, too. For reference, please read section (3).

The vulnerabilities can be attacked without user login. Tests were performed on IE (9.0) of Windows 8, Firefox (24.0) & Google Chromium 30.0.1599.114 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (12.10),Safari 6.1.6 of Mac OS X Lion 10.7.



(1.2) Facebook’s URL Redirection System Related to “*.php” Files

All URLs’ redirection are based on several files, such l.php, a.php, landing.php and so on.

The main redirection are based on file “l.php” (Almost all redirection links are using it right now).

For file “l.php”, one parameter “h” is used for authentication. When it mentions to file “a.php”, parameter “eid” is used for authentication. All those two files use parameter “u” for the url redirected to. In some other files such as “landing.php”, parameters such as “url”, “next” are used.

<1>For parameter “h”, two forms of authentication are used.

<a>h=HAQHyinFq

<b>h=hAQHalW1CAQHrkVIQNNqgwhxRWLNsFVeH3auuImlbR1CgKA

<2>For parameter “eid”, one form of authentication is used.

<a>eid=AQLP8sRq6lbU0jz0lARx9A9uetB6FIF1N2-Yjj_ePj0d_ezubjstZeDo6qDsalKVJwy6uDb_hQ-9tBsA2dVoQRq0lniOu0os_gPe3gY5l8lYblhQSwBtdvgjXjNqaxLZMYoasr3vv46tFsh1fL7q4kjT2LFw52dnJWd4SE8qc0YuPWfgPeQywgM2wl0CoW-lftWkr2dX0dLcytyHjXnvhKfVS_pQBllszUzsPENxE6EuZ-53Lh188o56idnfyyk2L58pE7C94PF-za4ZVB0qbuA2EnPcSJI-7oIiIJmIhifHe0CYTzG512-Z_heN44VlyJHevhS9auAR8-lFCAIlYymnT_Qiwp92RxjNOfBypBvszQUrvB6PH3fANn1prfMBVm4RD_GFel14KVDS5USswbTOTkL3sZNhHUqqPHwBwU3JFePMMuwsfesigH85B_AxCsXUIWN7klKGSq8bPPsKSHttsa9hkkMpSfRKL7D_xwW4dU2xlmfGWil7jYRJmwfbOeF0zujk1FRBuM757tbfFMav-J-K9npbdrDrCuUVqV__Tf7CGZ89nPl-M2d09pE9enJj0OBXOaSXZX16LKaYnv1Wh4GKme7C-EOunITxyQtp1zy-48Uaz9mxO2x4bw7sBDfzDStF_Al8_0SMjWNTh-J38rBHAgT96X-dPFI43HU3x3fVymE9szrclBpvTaSfYezatgMzf77s3lQrQAMSlwSSRIzRuoFvQBmWKT0T5ZFgH5ykhYKhNMiKj577UO5g2Ojm-_-KKF4N_DBuG5R-I6EOSlhok2xUkpKVDnDcxZFTLxGmx5xc56J5kZLjJ96wnF2fH09Q19Qc2aU3xYFlEFrKjrlLpwGyOyCDx7_z7y1O4Efqew3Fa0Cb9s6Kk2jpLF5XEIaYzzXOLAffxXG6icBJVovb9RPmiZ5s9dKYYotLol68_X04O05bEvVccPEh-IQwX_VTMt3f23be2MECEqR2l1A1ZkJx4qP00GI1pZhU_CXAnjSaTNmtaINRUeSsLNEZZsPwpWJMfeeGSwuof9krC05eSWjO0jH9tua0KteMYhj8i-3dwSBp4f7nMcFwH5ltfCLhMCYNB8rxgzcAczyhLIo2UY-3FSaJXBZ0lvuZBvnj7myUnyc2lCcy-fWh93MRRaJrrinjtfr9fDSMHM9Cja5xi0eG3Vs0aClnWbeJZA79TvmYt7E53HfwGuv5-EJOqRh3cwZF-53uPHA73ikUk3xTApjQunJM4uIBhpy7iBIgn_OXXo3X03YUJtJcDuC20ocJbZ310VHliox5tYZF2oiMaOfgo9Y9KeqgsrJgwPCJeif4aB0Ne4g_oM_Tuqt2pXbdgoCawHIApF087eFKJqejp0jpEkJerXPyK-IqsD_SQfIm_2WJSkzwzATwQKs

Those vulnerabilities were reported to Facebook in 2014 and they have been patched.





Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. Facebook 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!” All the fllowing web securities have been published here, Buffer overflow, HTTP Response Splitting (CRLF), CMD Injection, SQL injection, Phishing, Cross-site scripting, CSRF, Cyber-attack, Unvalidated Redirects and Forwards, Information Leakage, Denial of Service, File Inclusion, Weak Encryption, Privilege Escalation, Directory Traversal, HTML Injection, Spam. Large number of Facebook bugs were published here. FD also publishes suggestions, advisories, solutions details related to Open Redirect vulnerabilities and cyber intelligence recommendations.








(4) Amazon Covert Redirect Security Vulnerability Based on Facebook

Since Facebook is trusted by large numbers of other websites. Those vulnerabilities can be used to do “Covert Redirect” to other websites such as Amazon.


Domain:
http://www.amazon.com


“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)

 

 

The vulnerability exists at “redirect.html?” page with “&location” parameter, e.g.

 

(4.1) When a user is redirected from Amazon to another site, Amazon will check parameters “&token”. If the redirected URL’s domain is OK, Amazon will allow the reidrection.

However, if the URLs in a redirected domain have open URL redirection vulnerabilities themselves, a user could be redirected from Amazon 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 Amazon directly.

One of the vulnerable domain is,
http://www.facebook.com

 

(4.2) Use one of webpages for the following tests. The webpage address is “http://www.inzeed.com/kaleidoscope“. Suppose it is malicious.

Vulnerable URL:
