• PR:N (No Privileges Required): No privileges are required to exploit the vulnerability.
• UI:N (No User Interaction): No user interaction is required to exploit the vulnerability.
• VC:H (High Confidentiality Impact): Complete loss of system confidentiality.
• VI:H (High Integrity Impact): Complete loss of system integrity.
• VA:H (High Availability Impact): Complete loss of system availability.
• SC:L (Low Confidentiality Requirement): Confidentiality is not a significant requirement.
• SI:L (Low Integrity Requirement): Integrity is not a significant requirement.
• SA:H (High Availability Requirement): Availability is a significant requirement.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Code Execution (RCE): An attacker can exploit the vulnerability by crafting a malicious file that includes PHP code designed to execute arbitrary system commands.
• File Inclusion: The attacker can manipulate the filename parameter to include a malicious file from a remote server, leading to code execution.

Exploitation Methods:

• Crafting Malicious Files: The attacker can create a PHP file with malicious code and manipulate the include/require statements to execute this file.
• Network-Based Attacks: Since the vulnerability is exploitable over the network, attackers can target the application remotely without needing physical access.
