En las versiones afectadas, los Mensajes Firmados en Texto Claro de OpenPGP son mensajes firmados criptogr\u00e1ficamente donde el texto firmado es legible sin herramientas especiales. Estos mensajes suelen contener una cabecera 'Hash: ...' que declara el algoritmo hash utilizado para calcular el resumen de la firma. OpenPGP.js hasta la v5.9.0 ignoraba cualquier dato que precediera a los textos 'Hash: ...' al verificar la firma. Como resultado, partes maliciosas podr\u00edan a\u00f1adir texto arbitrario a un Mensaje Firmado en Texto Claro de terceros, para hacer creer a la v\u00edctima que el texto arbitrario estaba firmado. Un usuario o aplicaci\u00f3n es vulnerable a dicho vector de ataque si verifica el CleartextMessage comprobando \u00fanicamente la propiedad `verified` devuelta, descartando la informaci\u00f3n `data` asociada, y en su lugar _confiando visualmente_ en el contenido del mensaje original. Dado que `verificationResult.data` siempre contendr\u00eda los datos firmados reales, los usuarios y las aplicaciones que comprueban esta informaci\u00f3n no son vulnerables. De manera similar, dado un objeto CleartextMessage, la recuperaci\u00f3n de los datos utilizando `getText()` o el campo `text` devuelve solo el contenido que se considera al verificar la firma. Finalmente, volver a 'armar' un objeto CleartextMessage (utilizando `armor()`) tambi\u00e9n resultar\u00e1 en una versi\u00f3n 'sanitizada', con el texto extra\u00f1o eliminado. Este problema se ha solucionado en la versi\u00f3n 5.10.1 (versi\u00f3n estable actual) que rechazar\u00e1 los mensajes al llamar a `openpgp.readCleartextMessage()` y en la versi\u00f3n 4.10.11 (versi\u00f3n heredada) que rechazar\u00e1 los mensajes al llamar a `openpgp.cleartext.readArmored()`. Se aconseja a los usuarios que actualicen. Los usuarios que no puedan actualizar deber\u00edan comprobar el contenido de `verificationResult.data` para ver qu\u00e9 datos fueron realmente firmados, en lugar de confiar visualmente en el contenido del mensaje 'armado'."}], "id": "CVE-2023-41037", "lastModified": "2026-06-17T06:20:13.173", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 4.3, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "LOW", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N", "version": "3.1"}, "exploitabilityScore": 2.8, "impactScore": 1.4, "source": "security-advisories@github.com", "type": "Secondary"}, {"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 4.3, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "LOW", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N", "version": "3.1"}, "exploitabilityScore": 2.8, "impactScore": 1.4, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2023-41037", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2024-09-30T17:34:19.116832Z", "version": "2.0.3"}}]}, "published": "2023-08-29T17:15:13.003", "references": [{"source": "security-advisories@github.com", "tags": ["Patch"], "url": "https://github.com/openpgpjs/openpgpjs/commit/6b43e02a254853f5ff508ebd1b07541f78b7c566"}, {"source": "security-advisories@github.com", "tags": ["Exploit", "Vendor Advisory"], "url": "https://github.com/openpgpjs/openpgpjs/security/advisories/GHSA-ch3c-v47x-4pgp"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://github.com/openpgpjs/openpgpjs/commit/6b43e02a254853f5ff508ebd1b07541f78b7c566"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Exploit", "Vendor Advisory"], "url": "https://github.com/openpgpjs/openpgpjs/security/advisories/GHSA-ch3c-v47x-4pgp"}], "sourceIdentifier": "security-advisories@github.com", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-347"}], "source": "security-advisories@github.com", "type": "Secondary"}]}
