La vulnerabilidad surge porque Web Research Retriever no restringe las solicitudes a direcciones de Internet remotas, lo que le permite llegar a direcciones locales. Esta falla permite a los atacantes ejecutar escaneos de puertos, acceder a servicios locales y, en algunos escenarios, leer metadatos de instancias de entornos de nube. La vulnerabilidad es particularmente preocupante ya que puede explotarse para abusar del servidor Web Explorer como proxy para ataques web a terceros e interactuar con servidores en la red local, incluida la lectura de sus datos de respuesta. Esto podr\u00eda conducir potencialmente a la ejecuci\u00f3n de c\u00f3digo arbitrario, dependiendo de la naturaleza de los servicios locales. La vulnerabilidad se limita a las solicitudes GET, ya que las solicitudes POST no son posibles, pero el impacto en la confidencialidad, la integridad y la disponibilidad es significativo debido al potencial de robo de credenciales e interacciones de cambio de estado con las API internas."}], "id": "CVE-2024-3095", "lastModified": "2024-06-07T14:56:05.647", "metrics": {"cvssMetricV30": [{"cvssData": {"attackComplexity": "HIGH", "attackVector": "PHYSICAL", "availabilityImpact": "NONE", "baseScore": 4.8, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.0/AV:P/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N", "version": "3.0"}, "exploitabilityScore": 0.4, "impactScore": 4.0, "source": "security@huntr.dev", "type": "Secondary"}]}, "published": "2024-06-06T19:15:59.160", "references": [{"source": "security@huntr.dev", "url": "https://huntr.com/bounties/e62d4895-2901-405b-9559-38276b6a5273"}], "sourceIdentifier": "security@huntr.dev", "vulnStatus": "Awaiting Analysis", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-918"}], "source": "security@huntr.dev", "type": "Primary"}]}
