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)

The "lhfs" component suggests the challenge interacts directly with the host's file system. Common attack vectors include: lhfs_1zip
