CVE-2013-4330: Apache Camel critical disclosure vulnerability

Severity: Critical

Vendor: The Apache Software Foundation

Versions Affected: Camel 2.9.0 to 2.9.7, Camel 2.10.0 to 2.10.6, Camel
2.11.0 to 2.11.1, Camel 2.12.0
The unsupported Camel 2.3.x, 2.4.x, 2.5.x, 2.6.x, 2.7.x and 2.8.x versions
may be also affected.

Description: When sending an Exchange with the in Message Header
'CamelFileName' with a value of '$simple{...}' to a FILE or FTP producer,
it will interpret the value as simple language expression which can be
exploited by a malicious user.

Mitigation: 2.9.x users should upgrade to 2.9.8, 2.10.x users should
upgrade to 2.10.7, 2.11.x users should upgrade to 2.11.2 and 2.12.0 users
should upgrade to 2.12.1. This patch will be included from Camel 2.13.0:
https://git-wip-us.apache.org/repos/asf?p=camel.git;a=commitdiff;h=27a9752a565fbef436bac4fcf22d339e3295b2a0

Example: Create a simple route which moves files from one directory to
another, e.g.:
from("file:c:/tmp/in")
  .to("file:/c:/tmp/out");

If you are using Windows, create an file with the name
"$simple{camelContext.getClassResolver.resolveClass('java.lang.Runtime').getDeclaredMethods()[5].invoke(null,null).exec('calc.exe')}"
(without the quotes)
and drop it into the "c:/tmp/in" directory. The file consumer will read and
process this file. It will also set the Exchange in Message Header
'CamelFileName' with the value
"$simple{camelContext.getClassResolver.resolveClass('java.lang.Runtime').getDeclaredMethods()[5].invoke(null,null).exec('calc.exe')}".
In the next step, the file producer will interpreted the value of this
header as simple language expression and in this case, the Windows
calculator application will be started.
