NOTA: Un mantenedor externo ha declarado que este CVE es un informe falso. Afirman que la funci\u00f3n csrf_callback es en realidad una funci\u00f3n de devoluci\u00f3n de llamada para el manejador propio de la persona que llama para la salida. La funci\u00f3n llamada se puede cambiar a trav\u00e9s de la configuraci\u00f3n a una devoluci\u00f3n de llamada personalizada para manejar la validaci\u00f3n fallida de manera diferente. Tambi\u00e9n declararon que no hay forma de que un atacante cambie los tokens para que sean v\u00e1lidos desde el lado del cliente. Lo \u00fanico que puede hacer un ataque es extraer el token del javascript, pero eso siempre ser\u00e1 posible y no tiene nada que ver con la devoluci\u00f3n de llamada."}], "id": "CVE-2019-17590", "lastModified": "2026-06-17T02:24:14.120", "metrics": {"cvssMetricV2": [{"acInsufInfo": false, "baseSeverity": "MEDIUM", "cvssData": {"accessComplexity": "MEDIUM", "accessVector": "NETWORK", "authentication": "NONE", "availabilityImpact": "PARTIAL", "baseScore": 6.8, "confidentialityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:P", "version": "2.0"}, "exploitabilityScore": 8.6, "impactScore": 6.4, "obtainAllPrivilege": false, "obtainOtherPrivilege": false, "obtainUserPrivilege": false, "source": "nvd@nist.gov", "type": "Primary", "userInteractionRequired": true}], "cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 2.8, "impactScore": 5.9, "source": "nvd@nist.gov", "type": "Primary"}]}, "published": "2019-11-26T18:15:15.663", "references": [{"source": "cve@mitre.org", "tags": ["Exploit", "Third Party Advisory"], "url": "https://pastebin.com/01tDgq7u"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Exploit", "Third Party Advisory"], "url": "https://pastebin.com/01tDgq7u"}], "sourceIdentifier": "cve@mitre.org", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-352"}], "source": "nvd@nist.gov", "type": "Primary"}]}
