Bash Data Wrapper
1. Bash (Process Substitution & Here Documents)
| Technique | Description | Example Exploit |
|---|---|---|
| Process Substitution | Reads command output as a file stream. | cat <(echo "Injected Code") |
| Here Documents | Injects multi-line data into commands. | cat << EOF > payload.sh; echo "whoami"; EOF; bash payload.sh |
| File Descriptor Wrapping | Accesses file descriptors directly. | cat /proc/self/fd/0 <<< "Injected Data" |
