CVE-2022-32144 - Insufficient Input Verification Vulnerability in Huawei Product Resulting in Service Abnormality

In recent times, an insufficient input verification vulnerability has been discovered in a Huawei product. When exploited, this vulnerability can potentially cause the product's services to function abnormally. The Vulnerability ID allocated to this issue is HWPSIRT-2022-76192, and it has been assigned the Common Vulnerabilities and Exposures (CVE) ID: CVE-2022-32144.

In this post, we will take a closer look at CVE-2022-32144, the potential impact it can have when exploited, and the steps that you can take to safeguard your systems against this vulnerability. We'll also provide some code snippets, links to the original references, and details on how the exploit works.

Exploit Details

The vulnerability stems from insufficient input verification in a Huawei product. This means that an attacker can potentially send malicious input to the product, which may not be adequately validated. This, in turn, can lead to service abnormality and affect the product's regular operation.

The potential impact of this vulnerability is moderate, and successful exploitation can disrupt the affected Huawei product's normal functioning. To exploit the vulnerability, an attacker would need network access to the product and must be able to send malicious input to the affected component.

Code Snippet

The following is a hypothetical example of exploiting the input verification vulnerability, allowing an attacker to compromise the service in question. Note that this snippet is for illustrative purposes only and may not be directly applicable to the specific product in question.

import requests

url = "http://huawei_product_vulnerable_component.com"; # Replace with the actual URL
payload = {
	"malicious_input": "Exploit payload" # Replace with the actual exploit payload
}

# Sending a POST request with the malicious payload
response = requests.post(url, data=payload)

if response.status_code == 200:
	print("Successfully exploited the vulnerability")
else:
	print("Exploitation failed")
