HP Color LaserJet Pro M479fdw cacheddata_http_handler Stack-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of HP Color LaserJet Pro M479fdw printers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the cacheddata_http_handler method. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root.
