La vulnerabilidad permite abusar de la aplicaci\u00f3n por fraude o acceso no autorizado a cierta informaci\u00f3n. El ataque requiere una cuenta de usuario v\u00e1lida para conectarse al servidor Blue Prism, pero no se necesita que los roles asociados a esta cuenta tengan permisos. En primer lugar, los archivos de aplicaci\u00f3n se modifican para otorgar todos los permisos del lado del cliente. En un entorno de prueba (o su propia instancia del software), un atacante puede otorgarse privilegios completos tambi\u00e9n del lado del servidor. Luego puede, por ejemplo, dise\u00f1ar un proceso con comportamiento malicioso y exportarlo a un disco. Con el cliente modificado, es posible importar el archivo exportado como una versi\u00f3n y sobrescribir cualquier proceso existente en la base de datos. Eventualmente, los bots ejecutan el proceso malicioso. El servidor no comprueba los permisos del usuario para las acciones antes mencionadas, de modo que una modificaci\u00f3n del programa cliente habilita este clase de ataque. Los posibles escenarios pueden implicar cambiar cuentas bancarias o establecer contrase\u00f1as."}], "id": "CVE-2019-11875", "lastModified": "2026-06-17T02:13:47.200", "metrics": {"cvssMetricV2": [{"acInsufInfo": false, "baseSeverity": "MEDIUM", "cvssData": {"accessComplexity": "LOW", "accessVector": "NETWORK", "authentication": "SINGLE", "availabilityImpact": "PARTIAL", "baseScore": 6.5, "confidentialityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "vectorString": "AV:N/AC:L/Au:S/C:P/I:P/A:P", "version": "2.0"}, "exploitabilityScore": 8.0, "impactScore": 6.4, "obtainAllPrivilege": false, "obtainOtherPrivilege": false, "obtainUserPrivilege": false, "source": "nvd@nist.gov", "type": "Primary", "userInteractionRequired": false}], "cvssMetricV30": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.0"}, "exploitabilityScore": 2.8, "impactScore": 5.9, "source": "nvd@nist.gov", "type": "Primary"}]}, "published": "2019-05-24T16:29:00.437", "references": [{"source": "cve@mitre.org", "tags": ["Exploit", "Third Party Advisory", "VDB Entry"], "url": "http://packetstormsecurity.com/files/153007/Blue-Prism-Robotic-Process-Automation-RPA-Privilege-Escalation.html"}, {"source": "cve@mitre.org", "tags": ["Exploit", "Third Party Advisory"], "url": "https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-002.txt"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Exploit", "Third Party Advisory", "VDB Entry"], "url": "http://packetstormsecurity.com/files/153007/Blue-Prism-Robotic-Process-Automation-RPA-Privilege-Escalation.html"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Exploit", "Third Party Advisory"], "url": "https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-002.txt"}], "sourceIdentifier": "cve@mitre.org", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-669"}, {"lang": "en", "value": "CWE-862"}], "source": "nvd@nist.gov", "type": "Primary"}]}
