For the second time at Pwn2Own competition, network printers have been featured in Toronto 2022. The same brands were included this year as in Austin 2021: HP, Lexmark and Canon with equivalent model. Unlike the previous event, we only targeted the Lexmark and Canon but nevertheless manage to compromise both. Sadly, the bug we exploited for the Canon printer was previously used by another team in the competition. Anyway, this is how we achieved code execution on the Canon printer.
