Furlzz – Advanced iOS URL Scheme Fuzzing Made Easy

Furlzz is a small fuzzer written to test out iOS URL schemes. It does so by attaching to the application using Frida and based on the input/seed it mutates the data and tries to open the mutated URL.

Furlzz works in-process, meaning you aren’t actually opening the URL using apps such as SpringBoard. furlzz supports universal links which are being used with scene:continueUserActivity. Installation

Download prebuilt binaries from here or do it manually.

To manually install furlzz, do:

* Follow the instructions for devkit documented here
* Run go install github.com/nsecho/furlzz@latest Usage

$ furlzz fuzz --help
Fuzz URL scheme

Usage:
  furlzz fuzz [flags]

Flags:
  -a, --app string        Application name to attach to (default "Gadget")
  -b, --base string       base URL to fuzz
  -c, --crash             ignore previous crashes
  -d, --delegate string   if the method is scene_activity, you need to specify UISceneDelegate class
  -f, --function string   apply the function to mutated input (url, base64)
  -h, --help              help for fuzz
  -i, --input string      path to input directory
  -m, --method string     method of opening url (delegate, app) (default "delegate")
  -r, --runs uint         number of runs
  -s, --scene string      scene class name
  -t, --timeout uint      sleep X seconds between each case (default 1)
  -u, --uiapp string      UIApplication name

There are basically two ways you can go with fuzzing using furlzz:

* give base URL (--base) with FUZZ keyword in it along with --input directory containing inputs
* just give base URL without FUZZ keyword which would fuzz the raw base url passed (less efficient)

furlzz supports two post-process methods right now; url and base64. The first one does URL encode on the mutated input while the second one generates base64 from it. Fuzzing

1. Figure out the method of opening URLs inside the application (with frida-trace for example)
2. Find out base url
3. Create some inputs
4. Pass the flags to furlzz fuzz
5. Most of the time, values have to be URL encoded, so use --function url
6. Adjust timeout if you would like to go with slower fuzzing
7. If the crash happen, replay it with furlzz crash passing created session and crash files

* insert – inserts random byte at random location inside the input
* del – deletes random byte
* substitute – substitute byte at random position with random byte
* byteOp – takes random byte and random position inside the string and do arithmetic operation on them (+, -, *, /)
* duplicateRange – duplicates random range inside the original string random number of times
* bitFlip – flips the bit at random position inside random location inside input
* bitmask – applies random bitmask on random location inside the string
* duplicate – duplicates original string random number of times (2 < 10)
* multiple – run other mutations random number of times URL Open Methods

Right now furlzz supports two methods of opening URLs:

* delegate when the application uses -[AppDelegate application:openURL:options:]
* app when the application is using -[UIApplication openURL:]
* scene_activity – when the application is using -[UISceneDelegate scene:continueUserActivity]
* scene_context when the application is using -[UISceneDelegate scene:openURLContexts:] Additional Flags

* For the method of scene_activity you need to pass the UISceneDelegate class name
* For the method of delegate you need to pass the AppDelegate class name
* For the method of scene_context you need to pass UISceneDelegate class name

PRs are more than welcome to extend any functionality inside the furlzz
