paypal hack no survey guaranteed – paypal hack hackforums – paypal hack working 2017Today I am going to publicly disclose a critical vulnerability I have found during my research in PayPal, This vulnerability enabled me to completely bypass the CSRF Prevention System implemented by PayPal, The vulnerability is patched very fast and PayPal paid me the maximum bounty they give ;).**1- Reusable CSRF Token:*The CSRF token “that authenticate every single request made by the user” which can be also found in the request body of every request with the parameter name “Auth” get changed with every request made by user for security measures, but after a deep investigation I found out that the CSRF Auth is Reusable for that specific user email address or username, this means If an attacker found any of these CSRF Tokens, He can then make actions in the behalf of any logged in user.*Hmm, it seems interesting but still not exploitable, as there is no way for an attacker to get the “Auth” value from a victim session.**2- Bypassing the CSRF Auth System:*The CSRF Auth verifies every single request of that user, So what If an attacker “not logged in” tries to make a “send money” request then PayPal will ask the attacker to provide his email and password, The attacker will provide the “Victim Email” and ANY password, Then he will capture the request, The request will contain a Valid CSRF Auth token Which is Reusable and Can authorise this specific user requests. Upon Further Investigation, We have found out that an Attacker can obtain the CSRF Auth which can be valid for ALL users, by intercepting the POST request from a page that provide an Auth Token before the Logging-in process, check this page for the magical CSRF Auth “ At this point the attacker Can CSRF “almost” any request on behalf of this user.*Through examination of the password change process, I have found that an attacker can NOT Change the victim password without answering the Security Questions set by user, Also the user himself can NOT change the security questions without entering the password!**3- ByPassing the Security Questions Change:*Screen Shot 2014-08-13 at 12.20.52 AM*The initial process of “setting” security questions is not password protected and is reusable*After further investigation, I have noticed that the request of setting up the security questions “which is initiated by the user while signing up” is not password-protected, and it can be reused to reset the security questions up without providing the password, hence, Armed with the CSRF Auth, an attacker can CSRF this process too and change the victim’s Security questions.**At this point, An attacker can conduct a targeted CSRF attack against PayPal users and take a full control over their accounts. Hence, An attacker can CSRF all the requests including but not limited to:**1- Add/Remove/Confirm Email address*2-Add fully privileged users to business account*3- Change Security questions*4- Change Billing/Shipping Address*5- Change Payment methods*6- Change user settings(Notifications/Mobile settings) ………… and more.*To automate the whole process, I have coded a Python interactive server to demonstrate how an attacker can exploit this vulnerability in a real-life scenario attack.PayPal’s corporate headquarters are located in San Jose, California,[40] at North First Street campus.[54] The company’s operations center is located in Omaha, Nebraska, which opened in 1999.[55][56] Since July 2007, PayPal has operated across the European Union as a Luxembourg-based bank. The PayPal European headquarters are located in Luxembourg and the international headquarters are in Singapore. PayPal opened a technology center in Scottsdale, Arizona in 2006,[57] and a software development center in Chennai, India in 2007.[58] In October 2007, PayPal opened a data service office on the north side of Austin, Texas,[59] and also opened a second operations center in La Vista, Nebraska that same year.[55] In 2011, joining similar customer support operations located in Berlin (Germany), Chandler (Arizona), Dublin (Ireland), Omaha (Nebraska), and Shanghai (China), PayPal opened a second customer support center in Kuala Lumpur (Malaysia) and began the hiring process.[60] In 2014, PayPal opened a new global center of operations in Kuala Lumpur (Malaysia)[Litigation[edit]*In March 2002, two PayPal account holders separately sued the company for alleged violations of the Electronic Funds Transfer Act (EFTA) and California law. Most of the allegations concerned PayPal’s dispute resolution procedures. The two lawsuits were merged into one class action lawsuit (In re: PayPal litigation). An informal settlement was reached in November 2003, and a formal settlement was signed on June 11, 2004. The settlement requires that PayPal change its business practices (including changing its dispute resolution procedures to make them EFTA-compliant), as well as making a US$9.25 mill
