What is CVE-2022-24674?

This vulnerability affects the Canon imageCLASS MF644Cdw printer model, allowing network-adjacent attackers to execute arbitrary code without requiring any form of authentication. The vulnerability is found within the privet API, which lacks proper validation of user-supplied data lengths. This flaw enables malicious actors to exploit the fixed-length stack-based buffer, executing code with root privileges, thereby compromising the device and potentially affecting the network it operates on.
