• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Authentication (AT): None (N) - No authentication is required to exploit the vulnerability.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required to exploit the vulnerability.
• Confidentiality (VC): High (H) - Complete loss of confidentiality.
• Integrity (VI): High (H) - Complete loss of integrity.
• Availability (VA): High (H) - Complete loss of availability.

2. Potential Attack Vectors and Exploitation Methods

Given the nature of the vulnerability, potential attack vectors include:

• Remote Access: Attackers can exploit the vulnerability over the network, making it accessible from anywhere with network connectivity.
• Automated Scanning: Attackers can use automated tools to scan for devices with default credentials, making large-scale attacks feasible.
• Credential Stuffing: Attackers can use known default credentials to gain access to multiple devices.

Exploitation methods may involve:

• Brute Force Attacks: Using default credentials to gain access.
• Scripted Attacks: Automating the process of logging in with default credentials to multiple devices.
• Phishing: Tricking users into revealing default credentials, although this is less likely given the nature of the vulnerability.

3. Affected Systems and Software Versions

The affected systems include:

• SODOLA SL902-SWTGW124AS: Firmware versions through 200.1.20.

This vulnerability affects all devices running the specified firmware versions, making them susceptible to unauthorized access and control.
