» Hacking the Canon imageCLASS MF742Cdw/MF743Cdw (again)
Last year I (successfully) targeted the CANON Printer for Pwn2Own toronto, this year I decided to do the same. But I made a terrible mistake. The night before my flight to toronto I realized I had.. hacked the wrong printer (firmware). I scrambled to blindly port the exploit to the correct firmware image, without being able to actually test it. The exploit didn’t work during the competition. Anyway,
here is the story behind the bug and an 0day exploit for Canon imageCLASS MF743Cdw.
