(Pwn2Own) Canon imageCLASS MF743Cdw cmNetBiosParseName Heap-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Canon imageCLASS MF743Cdw printers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of NetBIOS names. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the NetBIOS-NS service.
