CVE-2022-24673 : Security Advisory and Response

This article provides details on CVE-2022-24673, a vulnerability that allows remote attackers to execute arbitrary code on affected Canon imageCLASS MF644Cdw 10.02 printers without requiring authentication.

Understanding CVE-2022-24673

In this section, we will explore what CVE-2022-24673 is, its impact, technical details, and mitigation strategies.

What is CVE-2022-24673?

CVE-2022-24673 is a vulnerability that exists within the implementation of the SLP protocol on Canon imageCLASS MF644Cdw 10.02 printers. It allows remote attackers to execute code in the context of root without the need for authentication.

The Impact of CVE-2022-24673

The lack of proper validation of user-supplied data length prior to copying it to a fixed-length stack-based buffer makes it possible for attackers to exploit this vulnerability, resulting in arbitrary code execution.

Technical Details of CVE-2022-24673

This section covers the vulnerability description, affected systems and versions, as well as the exploitation mechanism.
