Account takeover due to CSRF in "Account details" option on █████████
State Resolved (Closed)
Disclosed publicly 2019-01-11T13:02:29.557Z
Reported To
Weakness Cross-Site Request Forgery (CSRF)

submitted a report to U.S. Dept Of Defense .

Hi DoD team,
similarly to the previous CSRF that I've reported, I've found another CSRF in the same domain, but on the Account details option.

The CSRF issue allows me to modify the datas of every victim that is targeted using the CSRF file, and leading to account takeover simply setting my email as email of the victim: logging out I can recover the password of the infected account using the attacker-email that has replaced the victim-email.

Step-by-step Reproduction Instructions

  1. Login as victim and check your infos in the account details
  2. Open the CSRF malicious file {F346689}
  3. Recheck the infos: now the email is different (also the username) {F346690}

(In the video the @ char is replaced with %40 (url encoded version of the @ char), but is due to a problem in the CSRF value, simply replacing %40 to @ in the email parameter, the @ char appears).

For account takeover now:

  1. Go in anonymous mode (now you're the attacker that hasn't access to the accounts)
  2. The victim has opened the CSRF file, so your email is setted in the victim's account
  3. Go on the login, and request the Forgot password option, inserting the email used for replace the one of the victim
  4. You obtain a link for reset the password (I've not done a video, but if you can't reproduce the steps I can do one for these steps also :))

Suggested Mitigation/Remediation Actions
Use captchas and CSRF-tokens for be sure that the victim is changing the datas knowing that.


The ██████████████████ShopCart has a POST CSRF issue also in the account details, that can lead to account takeover replacing the email of the victim with the email of the attacker, and requesting a new password using the Forgot password option.

Hey Mik, I'm going to be playing around with trying to redact and disclose the report. If you see it come in and out of disclosure don't panic, trying to figure out how this thing works.
