HttpHeaderFilterStrategy so that case-variant header names such as 'CAmelExecCommandExecutable' are filtered out alongside 'CamelExecCommandExecutable'. The same setLowerCase(true) call was not applied to five non-HTTP HeaderFilterStrategy implementations: JmsHeaderFilterStrategy and ClassicJmsHeaderFilterStrategy in camel-jms, SjmsHeaderFilterStrategy in camel-sjms, CoAPHeaderFilterStrategy in camel-coap, and GooglePubsubHeaderFilterStrategy in camel-google-pubsub. Because those strategies use case-sensitive String.startsWith('Camel'/'camel') filtering while the Camel Exchange stores headers in a case-insensitive map, an attacker with JMS (or equivalent) producer access to the broker consumed by a Camel route can inject case-variant Camel internal headers, which are then resolved by downstream components such as camel-exec and camel-file using their canonical casing. This enables remote code execution and arbitrary file write on routes that forward JMS messages to header-driven components.\n\nThis issue affects Apache Camel: from 3.0.0 before 4.14.6, from 4.15.0 before 4.18.2, from 4.19.0 before 4.20.0.\n\nUsers are recommended to upgrade to version 4.20.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.6.

La misma llamada a setLowerCase(true) no se aplic\u00f3 a cinco implementaciones de HeaderFilterStrategy que no son HTTP: JmsHeaderFilterStrategy y ClassicJmsHeaderFilterStrategy en camel-jms, SjmsHeaderFilterStrategy en camel-sjms, CoAPHeaderFilterStrategy en camel-coap, y GooglePubsubHeaderFilterStrategy en camel-google-pubsub. Debido a que esas estrategias usan filtrado String.startsWith(\u2019Camel\u2019/\u2019camel\u2019) sensible a may\u00fasculas y min\u00fasculas mientras que el Camel Exchange almacena los encabezados en un mapa que no distingue entre may\u00fasculas y min\u00fasculas, un atacante con acceso de productor JMS (o equivalente) al broker consumido por una ruta Camel puede inyectar encabezados internos de Camel con variantes de may\u00fasculas y min\u00fasculas, los cuales son luego resueltos por componentes posteriores como camel-exec y camel-file usando su formato can\u00f3nico de may\u00fasculas y min\u00fasculas. Esto permite la ejecuci\u00f3n remota de c\u00f3digo y la escritura arbitraria de archivos en rutas que reenv\u00edan mensajes JMS a componentes impulsados por encabezados.\n\nEste problema afecta a Apache Camel: desde 3.0.0 antes de 4.14.6, desde 4.15.0 antes de 4.18.2, desde 4.19.0 antes de 4.20.0.\n\nSe recomienda a los usuarios actualizar a la versi\u00f3n 4.20.0, la cual corrige el problema.
