Hence, An attacker can CSRF all the requests including but not limited to:Ģ-Add fully privileged users to business accountĦ- Change user settings(Notifications/Mobile settings) ………… and more. The initial process of “setting” security questions is not password protected and is reusable.Īfter further investigation, 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.Īt this point, An attacker can conduct a targeted CSRF attack against a PayPal users and take a full control over his account. Through examination of the password change process, he found that an attacker can’t Change the victim password without answering the Security Questions set by user, Also the user himself can’t change the security questions without entering the password!ģ- ByPassing the Security Questions Change: The application generates a valid “Auth” token for a logged-out user! At this point the attacker Can CSRF “almost” any request on behave of this user. 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 “”. 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. 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. 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 behave of any logged in user. Yasser successfully bypassed the PayPal security to generate exploit code for targeted attacks. Yasser tells that How the security breach in paypal and hackers can hijack account just single click.
