Esta vulnerabilidad es diferente de CVE-2018-10994. El atacante necesita enviar c\u00f3digo HTML directamente como mensaje y, despu\u00e9s, responder a ese mensaje para desencadenar esta vulnerabilidad. El software Signal-Desktop no sanea los elementos HTML especiales que se pueden utilizar para inyectar c\u00f3digo HTML en las ventanas de chat remoto al responder a un mensaje HTML. Espec\u00edficamente, los elementos IMG e IFRAME pueden emplearse para incluir recursos remotos o locales. Por ejemplo, el uso de un elemento IFRAME habilita la ejecuci\u00f3n de c\u00f3digo total, lo que permite que un atacante descargue/suba archivos, informaci\u00f3n, etc. Se ha descubierto que el elemento SCRIPT tambi\u00e9n es inyectable. En el sistema operativo de Windows, CSP no evita la inclusi\u00f3n de recursos mediante el protocolo SMB. En este caso, la ejecuci\u00f3n remota de JavaScript puede lograrse referenciando el script en una compartici\u00f3n SMB en un elemento IFRAME, por ejemplo: >IFRAME src=\\\\DESKTOP-XXXXX\\Temp\\test.html> y despu\u00e9s contestando. El c\u00f3digo JavaScript incluido se ejecuta de forma autom\u00e1tica, sin que se necesite interacci\u00f3n por parte del usuario. La vulnerabilidad puede desencadenarse en el cliente Signal-Desktop mediante el env\u00edo de un mensaje especialmente manipulado y, despu\u00e9s, contestando con cualquier texto o contenido en la respuesta (no importa)."}], "id": "CVE-2018-11101", "lastModified": "2018-06-19T18:24:15.630", "metrics": {"cvssMetricV2": [{"acInsufInfo": false, "baseSeverity": "MEDIUM", "cvssData": {"accessComplexity": "MEDIUM", "accessVector": "NETWORK", "authentication": "NONE", "availabilityImpact": "NONE", "baseScore": 4.3, "confidentialityImpact": "NONE", "integrityImpact": "PARTIAL", "vectorString": "AV:N/AC:M/Au:N/C:N/I:P/A:N", "version": "2.0"}, "exploitabilityScore": 8.6, "impactScore": 2.9, "obtainAllPrivilege": false, "obtainOtherPrivilege": false, "obtainUserPrivilege": false, "source": "nvd@nist.gov", "type": "Primary", "userInteractionRequired": true}], "cvssMetricV30": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 6.1, "baseSeverity": "MEDIUM", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "privilegesRequired": "NONE", "scope": "CHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N", "version": "3.0"}, "exploitabilityScore": 2.8, "impactScore": 2.7, "source": "nvd@nist.gov", "type": "Primary"}]}, "published": "2018-05-17T19:29:00.557", "references": [{"source": "cve@mitre.org", "tags": ["Mailing List", "Patch", "Third Party Advisory"], "url": "http://seclists.org/fulldisclosure/2018/May/46"}], "sourceIdentifier": "cve@mitre.org", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-79"}], "source": "nvd@nist.gov", "type": "Primary"}]}
