Como mitigaci\u00f3n, los usuarios pueden aplicar una limitaci\u00f3n de velocidad o insertar retrasos aleatorios en las llamadas a la API realizadas al servidor GoCD por medio de un proxy inverso u otro servidor web de fachada. Otra mitigaci\u00f3n es que los usuarios no permitan el uso de tokens de acceso por parte de los usuarios haciendo que un administrador revoque todos los tokens de acceso mediante de la funci\u00f3n de administraci\u00f3n \"Access Token Management\""}], "id": "CVE-2022-39308", "lastModified": "2026-06-17T04:58:06.910", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 6.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "LOW", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N", "version": "3.1"}, "exploitabilityScore": 2.2, "impactScore": 4.2, "source": "security-advisories@github.com", "type": "Secondary"}, {"cvssData": {"attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 5.9, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N", "version": "3.1"}, "exploitabilityScore": 2.2, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2022-39308", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2025-04-23T13:56:20.518050Z", "version": "2.0.3"}}]}, "published": "2022-10-14T19:15:18.310", "references": [{"source": "security-advisories@github.com", "tags": ["Patch", "Third Party Advisory"], "url": "https://github.com/gocd/gocd/commit/236d4baf92e6607f2841c151c855adcc477238b8"}, {"source": "security-advisories@github.com", "tags": ["Release Notes", "Third Party Advisory"], "url": "https://github.com/gocd/gocd/releases/tag/19.11.0"}, {"source": "security-advisories@github.com", "tags": ["Third Party Advisory"], "url": "https://github.com/gocd/gocd/security/advisories/GHSA-999p-fp84-jcpq"}, {"source": "security-advisories@github.com", "tags": ["Release Notes", "Vendor Advisory"], "url": "https://www.gocd.org/releases/#19-11-0"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch", "Third Party Advisory"], "url": "https://github.com/gocd/gocd/commit/236d4baf92e6607f2841c151c855adcc477238b8"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Release Notes", "Third Party Advisory"], "url": "https://github.com/gocd/gocd/releases/tag/19.11.0"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Third Party Advisory"], "url": "https://github.com/gocd/gocd/security/advisories/GHSA-999p-fp84-jcpq"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Release Notes", "Vendor Advisory"], "url": "https://www.gocd.org/releases/#19-11-0"}], "sourceIdentifier": "security-advisories@github.com", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-208"}, {"lang": "en", "value": "CWE-1254"}], "source": "security-advisories@github.com", "type": "Secondary"}, {"description": [{"lang": "en", "value": "CWE-697"}], "source": "nvd@nist.gov", "type": "Primary"}]}
