CVE-2022-24673

CWE-121Published: March 28, 2023· Updated: Jun 17, 2026

9.8
CVSS v3.1

Official Description

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Canon imageCLASS MF644Cdw 10.02 printers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the SLP protocol. 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. Was ZDI-CAN-15845.

Risk Analysis

Canon imageCLASS printers are vulnerable to a stack-based buffer overflow in the SLP protocol implementation. This allows unauthenticated remote attackers to execute arbitrary code with root privileges.

The vulnerability is remotely exploitable with low complexity, but no public exploit is known and it is not in CISA KEV.

Recommended Action

Apply the latest firmware updates provided by Canon. Disable the SLP protocol if it is not required for printer operations.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2022-24673 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
