Background
The jt-jiffle package is a Java library that provides a scripting language for image processing. It is commonly used in applications that require dynamic image manipulation. This vulnerability allows an attacker to inject malicious code into the Jiffle script, which is then compiled and executed, leading to remote code execution. This vulnerability affects versions 0 to 1.1.22 of the jt-jiffle package.
Vulnerability Detail
The vulnerability arises from improper control of code generation in jt-jiffle. When a Jiffle script is provided via a network request, it is compiled into Java code using Janino and then executed. This allows an attacker to inject arbitrary code into the resulting script, leading to remote code execution. This vulnerability is particularly critical for applications that use jt-jiffle and allow Jiffle scripts to be provided externally, such as the GeoServer project.
How To Fix
Minimum fixed version
1.1.22
This is the first release that contains the fix.

Workaround
If updating the package is not immediately feasible, a workaround is to remove the janino-x.y.z.jar file from the classpath of the final application. This will negate the ability to compile Jiffle scripts, preventing the exploitation of this vulnerability.
Conclusion
The code injection vulnerability in jt-jiffle allows for remote code execution, posing a significant risk to applications that use Jiffle scripts provided externally. It is crucial to update to version 1.2.22 of the jt-jiffle package or apply the recommended workaround to mitigate this vulnerability.
