2. Authentication Bypass: The vulnerability may allow attackers to bypass authentication mechanisms entirely, gaining unauthorized access to the Wi-Fi Cloud Hotspot.
3. Denial of Service (DoS): Repeated authentication attempts can overwhelm the system, leading to a denial of service for legitimate users.

Exploitation Methods:

• Automated Scripts: Attackers can use automated scripts to generate and test multiple passwords rapidly.
• Network Sniffing: Capturing and analyzing network traffic to identify patterns and weaknesses in the authentication process.
• Social Engineering: Combining technical exploits with social engineering tactics to trick users into revealing credentials.

3. Affected Systems and Software Versions

Affected Systems:

• Art-in Bilişim Teknolojileri ve Yazılım Hizm. Tic. Ltd. Şti. Wi-Fi Cloud Hotspot

Software Versions:

• All versions before 30.05.2025

4. Recommended Mitigation Strategies

1. Implement Rate Limiting: Introduce rate limiting on authentication attempts to prevent brute force attacks.
2. Multi-Factor Authentication (MFA): Enforce MFA to add an additional layer of security.
3. Regular Patching: Ensure that the Wi-Fi Cloud Hotspot software is updated to the latest version that addresses this vulnerability.
4. Monitoring and Alerts: Implement monitoring tools to detect and alert on suspicious authentication activities.
