To exploit the vulnerability, one must register with a username identical to the victim's username, but with white space inserted before and/or after the username. This will register the account with the same username as the victim. After initiating a password reset for the new account, CTFd will reset the victim's account password due to the username collision." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "url": "https://github.com/CTFd/CTFd/pull/1218", "refsource": "MISC", "name": "https://github.com/CTFd/CTFd/pull/1218" }, { "refsource": "MISC", "name": "https://github.com/CTFd/CTFd/releases/tag/2.2.3", "url": "https://github.com/CTFd/CTFd/releases/tag/2.2.3" } ] } }
