• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high score reflects the ease of exploitation and the severe impact on confidentiality, integrity, and availability of the affected system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Since the attack vector is network-based, an attacker can exploit this vulnerability remotely without needing physical access to the system.
• Web Application Inputs: The primary attack vector is through web application inputs where user-supplied data is not properly sanitized before being used in SQL queries.

Exploitation Methods:

• SQL Injection: An attacker can craft SQL queries by injecting malicious code into input fields, such as login forms, search boxes, or any other user input fields that interact with the database.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL injection vulnerabilities, making it easier to identify and exploit this flaw.

3. Affected Systems and Software Versions

Affected Software:

• Veon Computer Service Tracking Software
• Versions: All versions before CRM 2.0
