Los encabezados cuidadosamente elaborados pueden hacer que el an\u00e1lisis de encabezados en Rack demore m\u00e1s de lo esperado, lo que resulta en un posible problema de denegaci\u00f3n de servicio. Los encabezados Aceptar y Reenviar se ven afectados. Ruby 3.2 tiene mitigaciones para este problema, por lo que las aplicaciones Rack que usan Ruby 3.2 o posterior no se ven afectadas. Esta vulnerabilidad se solucion\u00f3 en 2.0.9.4, 2.1.4.4, 2.2.8.1 y 3.0.9.1."}], "id": "CVE-2024-26146", "lastModified": "2026-06-17T07:17:11.747", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "LOW", "baseScore": 5.3, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L", "version": "3.1"}, "exploitabilityScore": 3.9, "impactScore": 1.4, "source": "security-advisories@github.com", "type": "Secondary"}, {"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 3.9, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2024-26146", "options": [{"exploitation": "none"}, {"automatable": "yes"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2024-02-29T17:31:54.207314Z", "version": "2.0.3"}}]}, "published": "2024-02-29T00:15:51.597", "references": [{"source": "security-advisories@github.com", "tags": ["Vendor Advisory"], "url": "https://discuss.rubyonrails.org/t/possible-denial-of-service-vulnerability-in-rack-header-parsing/84942"}, {"source": "security-advisories@github.com", "tags": ["Patch"], "url": "https://github.com/rack/rack/commit/30b8e39a578b25d4bdcc082c1c52c6f164b59716"}, {"source": "security-advisories@github.com", "tags": ["Patch"], "url": "https://github.com/rack/rack/commit/6c5d90bdcec0949f7ba06db62fb740dab394b582"}, {"source": "security-advisories@github.com", "tags": ["Patch"], "url": "https://github.com/rack/rack/commit/a227cd793778c7c3a827d32808058571569cda6f"}, {"source": "security-advisories@github.com", "tags": ["Patch"], "url": "https://github.com/rack/rack/commit/e4c117749ba24a66f8ec5a08eddf68deeb425ccd"}, {"source": "security-advisories@github.com", "tags": ["Vendor Advisory"], "url": "https://github.com/rack/rack/security/advisories/GHSA-54rr-7fvw-6x8f"}, {"source": "security-advisories@github.com", "tags": ["Third Party Advisory"], "url": "https://github.com/rubysec/ruby-advisory-db/blob/master/gems/rack/CVE-2024-26146.yml"}, {"source": "security-advisories@github.com", "tags": ["Mailing List"], "url": "https://lists.debian.org/debian-lts-announce/2024/04/msg00022.html"}, {"source": "security-advisories@github.com", "tags": ["Third Party Advisory"], "url": "https://security.netapp.com/advisory/ntap-20240510-0006/"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Vendor Advisory"], "url": "https://discuss.rubyonrails.org/t/possible-denial-of-service-vulnerability-in-rack-header-parsing/84942"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://github.com/rack/rack/commit/30b8e39a578b25d4bdcc082c1c52c6f164b59716"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://github.com/rack/rack/commit/6c5d90bdcec0949f7ba06db62fb740dab394b582"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://github.com/rack/rack/commit/a227cd793778c7c3a827d32808058571569cda6f"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://github.com/rack/rack/commit/e4c117749ba24a66f8ec5a08eddf68deeb425ccd"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Vendor Advisory"], "url": "https://github.com/rack/rack/security/advisories/GHSA-54rr-7fvw-6x8f"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Third Party Advisory"], "url": "https://github.com/rubysec/ruby-advisory-db/blob/master/gems/rack/CVE-2024-26146.yml"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Mailing List"], "url": "https://lists.debian.org/debian-lts-announce/2024/04/msg00022.html"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Third Party Advisory"], "url": "https://security.netapp.com/advisory/ntap-20240510-0006/"}], "sourceIdentifier": "security-advisories@github.com", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-1333"}], "source": "security-advisories@github.com", "type": "Secondary"}, {"description": [{"lang": "en", "value": "CWE-1333"}], "source": "nvd@nist.gov", "type": "Primary"}]}
