Upload or pass this file to the lhfs binary. If vulnerable, it will attempt to "extract" the file to that path or read from it, often leaking the contents in the process. Common Mitigation
Creating a symlink inside the archive that points to a sensitive system file. When the service "updates" or "reads" the file, it interacts with the system target instead. 3. Exploitation (General Example) lhfs_1zip
While a specific "official" write-up might be hosted on private CTF platforms (like Hack The Box or specific university labs), the challenge typically revolves around exploiting a implementation that handles .1zip files. Challenge Overview Upload or pass this file to the lhfs binary
If the extraction tool doesn't sanitize filenames, you can use ../ to write files outside the intended directory (e.g., overwriting .ssh/authorized_keys or /etc/passwd ). When the service "updates" or "reads" the file,
