• AC:L (Low): The attack complexity is low, meaning it does not require specialized conditions.
• PR:N (None): No privileges are required to exploit the vulnerability.
• UI:N (None): No user interaction is required.
• S:C (Changed): The vulnerability affects the confidentiality, integrity, and availability of the system.
• C:H (High): The confidentiality impact is high.
• I:N (None): The integrity impact is none.
• A:L (Low): The availability impact is low.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: An attacker can inject SQL commands through input fields that are not properly sanitized.
• Remote Exploitation: Given the network vector (AV:N), the attack can be executed remotely.

Exploitation Methods:

• Manual SQL Injection: Crafting SQL queries manually and injecting them into vulnerable input fields.
• Automated Tools: Using automated SQL injection tools to identify and exploit the vulnerability.
• Blind SQL Injection: If the application does not return error messages, blind SQL injection techniques can be used to extract data.

3. Affected Systems and Software Versions

Affected Software:

• Product: URL Shortener
