Apache Camel: Bean component: Camel Message Header Injection via Improper Filtering
漏洞描述信息
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.".
