CoreInject is a utility for injecting shared library objects (.so files) into running Linux processes. It can be useful for debugging, instrumentation, hacking, and more.

• Inject multiple shared libraries into a target process
• Bypass sandbox restrictions by relocating libraries
• Delete injected libraries after use
• Easy to use CLI

Basic usage:

CoreCLI -p 123 -m lib1.so -m lib2.so

This will inject lib1.so and lib2.so into the process with ID 123.

The following flags can be used to control injection behavior:

• --allowDoubleInjection: If enabled, then modules that are already loaded by the target process wont be filtered
• --workaroundSandboxes: Before injection, copy the library to the current working directory of the target process
• --overwriteRelocationTarget: If the target file already exists, then it will be overwritten (Requires --workaroundSandboxes)
• --deleteAfterInjection: Deletes the module after injection. In case of a sandbox workaround, this affects the relocated module, not the original
• --ignoreELFHeader: Allows modules with invalid elf header to be injected (also allows mismatching architectures)

To build:

mkdir Build
cd Build
cmake ..
cmake --build . -j $(nproc)

To install (run as root):

cmake --install .
