CVE-2022-22393: IBM WebSphere Application Server Liberty - Potential Information Disclosure Exploit

IBM WebSphere Application Server Liberty is a well-known, high-performance application server that is designed to help developers build, test, and deploy applications quickly and easily. Recently, a potential information disclosure vulnerability has been discovered in IBM WebSphere Application Server Liberty versions 17...3 through 22...5, specifically pertaining to the adminCenter-1. feature.

This vulnerability could allow an authenticated user to issue a request to obtain the status of the HTTP/HTTPS ports, which are accessible by the application server. The vulnerability has been assigned the CVE identifier CVE-2022-22393 and is currently being tracked by IBM X-Force ID: 222078. This post aims to provide details about this vulnerability, including code snippets, exploit details, and links to original references for further understanding.

adminCenter-1.

When exploiting this vulnerability, an authenticated user can issue a request to the application server to obtain the status of HTTP/HTTPS ports accessible by the server, potentially leading to information disclosure.

Here is a simple code snippet demonstrating how an attacker could potentially send an HTTP request to access the server's port status:

import requests

url = "https://target_server/adminCenter/api/ports";

headers = {
    "Authorization": "Bearer <auth_token_here>"
}

response = requests.get(url, headers=headers)

print(response.json())

In this snippet, the attacker would replace <auth_token_here> with their authentication token obtained through a successful login or authorization process. Once executing this script, the attacker would be able to view the server's HTTP/HTTPS ports status.

Mitigation

To address this issue, IBM has released a patch that should be applied immediately on the affected systems. The patch prevents authenticated users from accessing the sensitive port information without proper authorization.

For more information on how to apply the patch, users should refer to the IBM Security Bulletin for detailed instructions.
