shinyquagsire23/cve-2020-12753-pocUna prova di concetto per CVE-2020-12753
Questo repository contiene una proof-of-concept per 🔋📱❄️🥾🔓, una vulnerabilità SBL1/aboot per l'esecuzione arbitraria di codice in Secure EL3 su LG Stylo 4 (AMZ/Q710ULM). È stata testata solo sugli aggiornamenti 20a e 20c e con la variante SBL1 della vulnerabilità.
- Makefile : Builds raw_resources_a_mod.img given sbl_rop.s and raw_resources.img_884736
- raw_resources.img_884736 : Original raw_resources partition; sha256 510def86aa7608ac02f243d3c161bf973ac4add066be763c8abcb2fee90a454c
- raw_resources_a_mod.img : pre-compiled raw_resources partition to be flashed; sha256 26ee5f4589009bc20269bdb813a78d729b9daba44f7826560f6b7201f5396e73
- payload.bin : pre-compiled output of sbl_rop.s (no RLE compression)
- lg-craftres.py : Python3 script which takes in raw_resources.img_884736 and payload.bin and outputs raw_resources_a_mod.img
- sbl_rop.s : ROP payload to be written to the stack by load_res_888rle_image
- sbl_gadgets.s : ROP gadget defines for SBL1, included by sbl_rop.s
Per compilare dai sorgenti, sono necessari armips (https://github.com/Kingcom/armips) e Python 3.
