Twitter Kit for iOS versions 3.0 to 3.4.0 is vulnerable to a callback verification flaw in the \"Login with Twitter\" component allowing an attacker to provide alternate credentials. In the final step of \"Login with Twitter\" authentication information is passed back to the application using the registered custom URL scheme (typically twitterkit-<consumer-key>) on iOS. Because the callback handler did not verify the authenticity of the response, this step is vulnerable to forgery, potentially allowing attacker to associate a Twitter account with a third-party service."},{"lang":"es","value":"Esta vulnerabilidad fue generada por una corrección incompleta de CVE-2017-0911. El Twitter Kit para las versiones 3.0 hasta la 3.4.0 de iOS es vulnerable a un fallo en la comprobación de devolución de llamada en el componente \"Login with Twitter\" que permite a un atacante suministrar credenciales alternativas. En el paso final de \"Login with Twitter\", la información de autenticación se transmite a la aplicación usando el esquema de URL personalizado registered (generalmente twitterkit-) en iOS. Comenzando el controlador de devolución de llamada no se verificó la autenticidad de la respuesta, este paso es vulnerable a falsificación, lo que potencialmente permite al atacante asociar una cuenta de Twitter con un servicio de terceros."}],"affected":[{"source":"support@hackerone.com","affectedData":[{"vendor":"n/a","product":"Twitter Kit for iOS","versions":[{"version":"v3.4.2","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","baseScore":5.4,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":2.5}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:L/Au:S/C:P/I:P/A:N","baseScore":5.5,"accessVector":"NETWORK","accessComplexity":"LOW","authentication":"SINGLE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"NONE"},"baseSeverity":"MEDIUM","exploitabilityScore":8.0,"impactScore":4.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"support@hackerone.com","type":"Secondary","description":[{"lang":"en","value":"CWE-352"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-345"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:twitter:twitter_kit:*:*:*:*:*:iphone_os:*:*","versionStartIncluding":"3.0","versionEndIncluding":"3.4.0","matchCriteriaId":"1C73B3B9-59C6-43FD-99C1-30EF13AF0D0F"}]}]}],"references":[{"url":"https://blog.twitter.com/developer/en_us/topics/tips/2018/vulnerability-in-twitter-kit-for-ios.html","source":"support@hackerone.com","tags":["Vendor Advisory"]},{"url":"https://blog.twitter.com/developer/en_us/topics/tips/2018/vulnerability-in-twitter-kit-for-ios.html","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
