• 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): Confidentiality impact is high.
• I:H (High): Integrity impact is high.
• A:H (High): Availability impact is high.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Arbitrary File Upload: An attacker can upload malicious files, such as PHP scripts, to the server without needing any authentication.
• Remote Code Execution (RCE): By uploading a malicious script, an attacker can execute arbitrary code on the server, leading to full system compromise.
• Data Exfiltration: Attackers can upload scripts to exfiltrate sensitive data from the server.
• Persistent Backdoors: Attackers can upload backdoor scripts to maintain persistent access to the compromised server.

Exploitation Methods:

• Direct File Upload: Attackers can directly upload files through the vulnerable endpoint.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable installations and exploit them en masse.
• Phishing Campaigns: Attackers can use phishing to lure users into visiting a malicious site that exploits the vulnerability.

3. Affected Systems and Software Versions

Affected Software:

• Gora Tech LLC Cooked Pro Plugin
• Versions: All versions before 1.8.0

Affected Systems:

• WordPress Sites: Any WordPress site using the affected versions of the Cooked Pro plugin.
• Web Servers: Servers hosting WordPress sites with the vulnerable plugin.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update the Plugin: Immediately update the Cooked Pro plugin to version 1.8.0 or later.
• Disable the Plugin: If updating is not possible, disable the plugin until a secure version is available.
• Implement Web Application Firewalls (WAF): Use WAFs to block suspicious file uploads.
• Monitor Logs: Closely monitor server logs for any unusual file upload activities.

Long-Term Strategies:

• Regular Patch Management: Ensure all plugins and software are regularly updated.
