In this paper, we presented a downgrade vulnerability in the PS4's firmware, specifically in Update 1302. We demonstrated how an attacker can exploit this vulnerability to downgrade the PS4's firmware, potentially allowing for arbitrary code execution. We also presented a mitigation strategy, which is to update the PS4's firmware to the latest version. This research highlights the importance of secure firmware updates and the need for thorough validation and testing to prevent vulnerabilities. ps4 downgrade 1302 upd
