Comprehensive Technical Analysis of CVE-2024-13790

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-13790 CISA Vulnerability Name: CVE-2024-13790 CVSS Score: 9.8

The vulnerability in the MinimogWP – The High Converting eCommerce WordPress Theme allows for Local File Inclusion (LFI) via the 'template' parameter. This vulnerability is critical due to its high CVSS score of 9.8, indicating a severe risk. The LFI vulnerability enables unauthenticated attackers to include and execute arbitrary files on the server, potentially leading to code execution, data exfiltration, and bypassing access controls.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit the vulnerability without needing to authenticate, making it easier to target.
• Arbitrary File Inclusion: By manipulating the 'template' parameter, attackers can include files from the server, including sensitive configuration files or uploaded files.
• Code Execution: If attackers can upload files (e.g., images with embedded PHP code), they can execute arbitrary PHP code on the server.

Exploitation Methods:

• File Inclusion: Attackers can include files such as /etc/passwd to gather information about the server.
• Code Execution: By uploading a file with PHP code and including it via the 'template' parameter, attackers can execute commands on the server.
• Data Exfiltration: Sensitive data stored in files can be accessed and exfiltrated.

3. Affected Systems and Software Versions

Affected Software:

• MinimogWP – The High Converting eCommerce WordPress Theme
• Versions: All versions up to and including 3.7.0
