Bypass/Injection vulnerability in Apache Camel-Bean component under particular conditions. This issue affects Apache Camel: from 4.10.0 through <= 4.10.1, from 4.8.0 through <= 4.8.4, from 3.10.0 through <= 3.22.3. Users are recommended to upgrade to version 4.10.2 for 4.10.x LTS, 4.8.5 for 4.8.x LTS and 3.22.4 for 3.x releases. This vulnerability is only present in the following situation. The user is using one of the following HTTP Servers via one the of the following Camel components * camel-servlet * camel-jetty * camel-undertow * camel-platform-http * camel-netty-http and in the route, the exchange will be routed to a camel-bean producer. So ONLY camel-bean component is affected. In particular:  * The bean invocation (is only affected if you use any of the above together with camel-bean component). * The bean that can be called, has more than 1 method implemented. In these conditions an attacker could be able to forge a Camel header name and make the bean component invoking other methods in the same bean. The vulnerability arises due to a bug in the default filtering mechanism that only blocks headers starting with "Camel", "camel", or "org.apache.camel.".  Mitigation: You can easily work around this in your Camel applications by removing the headers in your Camel routes. There are many ways of doing this, also globally or per route. This means you could use the removeHeaders EIP, to filter out anything like "cAmel, cAMEL" etc, or in general everything not starting with "Camel", "camel" or "org.apache.camel.".

Description Bypass/Injection vulnerability in Apache Camel. This issue affects Apache Camel: from 4.10.0 through <= 4.10.1, from 4.8.0 through <= 4.8.4, from 3.10.0 through <= 3.22.3. Users are recommended to upgrade to version 4.10.2 for 4.10.x LTS, 4.8.5 for 4.8.x LTS and 3.22.4 for 3.x releases. The vulnerability arises due to a bug in the default filtering mechanism that only blocks headers starting with "Camel", "camel", or "org.apache.camel.". Attackers can bypass this filter by altering the casing of letters. This allows attackers to inject headers which can be exploited to invoke arbitrary methods from the Bean registry and also supports using Simple Expression Language (or OGNL in some cases) as part of the method parameters passed to the bean. It's important to note that only methods in the same bean declared in the bean URI could be invoked. Mitigation: You can easily work around this in your Camel applications by removing the headers in your Camel routes. There are many ways of doing this, also globally or per route. This means you could use the removeHeaders EIP, to filter out anything like "cAmel, cAMEL" etc, or in general everything not starting with "Camel", "camel" or "org.apache.camel.".
