Pathgen

Pathgen is a Golang CLI tool for generating arbitrary long paths on Linux

Installation

You need Golang to be installed in your environment. Pathgen has no external dependencies and only use the Go standard library.

go install github.com/mtardy/pathgen@latest

Usage

Usage:
  pathgen [flags] length

Flags:
  -b string
        binary to put at the end of the random path, used when write is enabled
  -c    cleanup everything under "/tmp/pathgen"
  -d int
        maximum length of a directory name (default 255)
  -l    create a symlink at "/tmp/pathgen/exe" to the target file, used when write is enabled (default true)
  -p string
        prefix for the random path, you will need to cleanup manually (default "/tmp/pathgen")
  -r    generate a random string for the path
  -s string
        suffix of the random path, name of the copied binary (default "bin")
  -w    write the filepath on the filesystem

For example, to generate a path of 512 bytes and put the binary nc at the end of random path under the name bin do:

pathgen -w -b $(which nc) 512

The output should be similar to:

You will find a symlink at /tmp/pathgen/exe that points to the binary that you can use to trigger execution from the arbitrary path.

ls -l /tmp/pathgen

The output should be similar to:
