👥 **Affected**: **HubBank** by vendor **Ofofonobs**. Specifically version **1.0.2**. If you are running this specific version, you are vulnerable.

💻 **Attacker Capabilities**: Full **Webshell execution**. This means: Read/Write files, execute system commands, steal sensitive banking data, and potentially pivot to other internal systems.

🔓 **Exploitation Threshold**: **Low**. Requires **Authenticated User** access (PR:L). No UI interaction needed (UI:N). Network accessible (AV:N). Once logged in, upload is trivial.

📜 **Public Exploit**: No specific PoC code listed in the data. However, the vulnerability type (Unrestricted Upload) is well-known. Exploitation is likely **manual** using standard PHP webshells.

🔍 **Self-Check**: 1. Log in as a registered user. 2. Navigate to 'upload document'. 3. Attempt to upload a `.php` file with a simple `<?php phpinfo(); ?>` payload. 4. Check if it executes.

🩹 **Fix Status**: Vendor **Ofofonobs** has not released a specific patch version in the data. Reference: [Incibe Notice](https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-hubbank).…

🚧 **Workaround**: If no patch: 1. **Disable** the 'upload document' feature if possible. 2. Implement strict **WAF rules** to block PHP file uploads. 3. Restrict upload directory execution permissions.

⚡ **Priority**: **CRITICAL (High)**. CVSS Score is **High** (likely 9.0+ based on vector). Immediate action required: Patch, isolate, or mitigate upload functionality immediately.
