• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Changed (C)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This vulnerability is critical due to its potential for complete system compromise with minimal effort from the attacker.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unrestricted File Upload: An attacker can upload a malicious file, such as a web shell, through the plugin's file upload functionality.
• Remote Code Execution (RCE): Once a web shell is uploaded, the attacker can execute arbitrary commands on the server.

Exploitation Methods:

• Web Shell Upload: The attacker can upload a PHP web shell, which allows them to execute commands on the server.
• Command Injection: Through the web shell, the attacker can inject commands to manipulate the server, exfiltrate data, or install additional malware.

3. Affected Systems and Software Versions

Affected Software:

• Boat Rental Plugin for WordPress
• Versions: From n/a through 1.0.1

Affected Systems:

• Any WordPress installation using the Boat Rental Plugin for WordPress within the specified version range.
