CVE-2023-49722: Open Port Vulnerability in BCC101/BCC102/BCC50 WiFi Firmware

Overview

The vulnerability, identified as CVE-2023-49722, is a critical flaw found in the WiFi firmware of the BCC101, BCC102, and BCC50 products. This vulnerability is due to an open network port, specifically port 8899, which could potentially allow an attacker to exploit the device and gain unauthorized access. This issue affects all users of these products connected to the same WiFi network. The severity of this vulnerability is underscored by its potential to compromise systems and leak sensitive data, making it a significant concern for both individual users and businesses alike.

BCC101 | All versions
BCC102 | All versions
BCC50 | All versions

How the Exploit Works

The exploit takes advantage of an open port in the WiFi firmware of the affected products. An attacker, when connected to the same WiFi network, can connect to this open port (8899) and gain unauthorized access to the device. This access could then be leveraged to compromise the system or leak sensitive data. The vulnerability does not require any user interaction or specific privileges, making it a potent threat on any unprotected network.

Conceptual Example Code

This conceptual example demonstrates how an attacker might connect to a device via the open port. Note that this is a simplified example and real-world attacks could be more complex or use different techniques.

# Establish connection to target device via port 8899
nc target_device_IP 8899
# Once connected, execute commands or deploy exploit code
echo "malicious_command_or_code" > /path/to/target

This example presumes the attacker already has access to the same WiFi network as the target device. Remember, the best defense against such an attack is to apply the vendor’s patch or, as a temporary mitigation, employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS).
