• AV:N (Attack Vector: Network): The vulnerability is exploitable over the network.
• AC:L (Attack Complexity: Low): The attack requires low complexity to exploit.
• PR:N (Privileges Required: None): No privileges are required to exploit the vulnerability.
• UI:N (User Interaction: None): No user interaction is required for the attack to succeed.
• S:C (Scope: Changed): The vulnerability affects a component that is different from the vulnerable component.
• C:H (Confidentiality: High): The vulnerability has a high impact on confidentiality.
• I:H (Integrity: High): The vulnerability has a high impact on integrity.
• A:H (Availability: High): The vulnerability has a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

Attackers can exploit this vulnerability by uploading files with dangerous types, such as executable scripts or malware, to the server. Potential attack vectors include:

• Web Shell Upload: Uploading a web shell to gain remote access to the server.
• Malware Distribution: Uploading malicious files that can be executed to infect the server or other connected systems.
• Data Exfiltration: Uploading scripts that can extract sensitive data from the server.
• Denial of Service (DoS): Uploading files that can crash the server or disrupt its services.

3. Affected Systems and Software Versions

The vulnerability affects the FW Food Menu plugin versions from n/a through 6.0.0. This means that all versions up to and including 6.0.0 are vulnerable. Users of this plugin should be particularly vigilant if they are running any version within this range.
