En estas condiciones, un atacante podr\u00eda falsificar un nombre de encabezado de Camel y hacer que el componente bean invoque otros m\u00e9todos en el mismo bean. La vulnerabilidad surge debido a un error en el mecanismo de filtrado predeterminado que solo bloquea los encabezados que comienzan con \\\"Camel\\\", \\\"camel\\\" u \\\"org.apache.camel\\\". Mitigaci\u00f3n: puedes solucionar esto f\u00e1cilmente en tus aplicaciones Camel eliminando los encabezados en tus rutas Camel. Hay muchas formas de hacer esto, tambi\u00e9n globalmente o por ruta. Esto significa que puedes usar el EIP removeHeaders para filtrar cualquier cosa como \\\"cAmel, cAMEL\\\", etc., o en general todo lo que no comience con \\\"Camel\\\", \\\"camel\\\" u \\\"org.apache.camel\\\".\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L\",\"baseScore\":5.6,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"LOW\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"LOW\"},\"exploitabilityScore\":2.2,\"impactScore\":3.4}]},\"weaknesses\":[{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-178\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:apache:camel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"3.10.0\",\"versionEndExcluding\":\"3.22.4\",\"matchCriteriaId\":\"F955C7FA-20EE-44FC-BB7F-2734A731A9DC\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:apache:camel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.8.0\",\"versionEndExcluding\":\"4.8.5\",\"matchCriteriaId\":\"15914F75-761B-40AD-8489-EA92699F3741\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:apache:camel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.10.0\",\"versionEndExcluding\":\"4.10.2\",\"matchCriteriaId\":\"DB496A7D-7E5D-48DA-B49F-4494B7369026\"}]}]}],\"references\":[{\"url\":\"https://camel.apache.org/security/CVE-2025-27636.html\",\"source\":\"security@apache.org\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://issues.apache.org/jira/browse/CAMEL-21828\",\"source\":\"security@apache.org\",\"tags\":[\"Issue Tracking\",\"Patch\"]},{\"url\":\"https://lists.apache.org/thread/l3zcg3vts88bmc7w8172wkgw610y693z\",\"source\":\"security@apache.org\",\"tags\":[\"Mailing List\",\"Vendor Advisory\"]},{\"url\":\"http://www.openwall.com/lists/oss-security/2025/03/09/1\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Mailing List\",\"Third Party Advisory\"]},{\"url\":\"https://camel.apache.org/security/CVE-2025-27636.txt.asc\",\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"tags\":[\"Exploit\"]},{\"url\":\"https://github.com/akamai/CVE-2025-27636-Apache-Camel-PoC/blob/main/src/main/java/com/example/camel/VulnerableCamel.java\",\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"tags\":[\"Product\"]}]}}"
