1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-30500 CISA Vulnerability Name: CVE-2024-30500 Description: Unrestricted Upload of File with Dangerous Type vulnerability in CubeWP CubeWP – All-in-One Dynamic Content Framework. This issue affects CubeWP – All-in-One Dynamic Content Framework: from n/a through 1.1.12.

CVSS Score: 9.9

Severity Evaluation: The CVSS score of 9.9 indicates a critical vulnerability. This high score is due to the potential for complete system compromise, including unauthorized access, data breaches, and remote code execution. The unrestricted file upload capability allows attackers to upload malicious files, which can lead to severe security breaches.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unrestricted File Upload: Attackers can upload files without proper validation, leading to the execution of malicious code.
• Remote Code Execution (RCE): By uploading files with dangerous types (e.g., PHP, JavaScript), attackers can execute arbitrary code on the server.
• Web Shell Upload: Attackers can upload web shells to gain persistent access to the server.

Exploitation Methods:

• File Upload Forms: Exploiting the vulnerability through file upload forms available in the CubeWP plugin.
• Automated Scripts: Using automated scripts to upload malicious files en masse.
• Phishing and Social Engineering: Tricking users into uploading malicious files through social engineering tactics.

3. Affected Systems and Software Versions

Affected Software:

• CubeWP – All-in-One Dynamic Content Framework
• Versions: from n/a through 1.1.12
