(Pwn2Own) ConnMan received_data Out-Of-Bounds Write Remote Code Execution Vulnerability

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installation of ConnMan. Authentication is not required to exploit this vulnerability. The specific flaw exists within the received_data method. Crafted data in a HTTP response can trigger a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the ConnMan process. This vulnerability was demonstrated on a Tesla Model 3 during Pwn2Own 2022 Vancouver competition.
