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."},{"lang":"es","value":"La validación incorrecta del nombre de usuario en el proceso de registro de CTFd v2.0.0 - v2.2.2 permite a un atacante hacerse cargo de una cuenta arbitraria si se conoce el nombre de usuario y se habilitan los correos electrónicos en la instancia de CTFd. Para explotar la vulnerabilidad, uno debe registrarse con un nombre de usuario idéntico al nombre de usuario de la víctima, pero con un espacio en blanco insertado antes y / o después del nombre de usuario. Esto registrará la cuenta con el mismo nombre de usuario que la víctima. Después de iniciar un restablecimiento de contraseña para la nueva cuenta, CTFd restablecerá la contraseña de la cuenta de la víctima debido a la colisión del nombre de usuario."}],"affected":[{"source":"cve@mitre.org","affectedData":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:M/Au:N/C:P/I:P/A:P","baseScore":6.8,"accessVector":"NETWORK","accessComplexity":"MEDIUM","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":8.6,"impactScore":6.4,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-640"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:ctfd:ctfd:*:*:*:*:*:*:*:*","versionStartIncluding":"2.0.0","versionEndIncluding":"2.2.2","matchCriteriaId":"A5C47875-21C5-4DA1-822C-03F195DE127B"}]}]}],"references":[{"url":"https://github.com/CTFd/CTFd/pull/1218","source":"cve@mitre.org","tags":["Third Party Advisory"]},{"url":"https://github.com/CTFd/CTFd/releases/tag/2.2.3","source":"cve@mitre.org","tags":["Release Notes"]},{"url":"https://github.com/CTFd/CTFd/pull/1218","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]},{"url":"https://github.com/CTFd/CTFd/releases/tag/2.2.3","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes"]}]}}]}
