Comprehensive Technical Analysis of CVE-2025-47452

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-47452 CISA Vulnerability Name: CVE-2025-47452 Description: The vulnerability allows for the unrestricted upload of files with dangerous types in RexTheme WP VR, enabling attackers to upload a web shell to a web server. This issue affects versions of WP VR from n/a through 8.5.26. 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 the execution of arbitrary code, data exfiltration, and unauthorized access to sensitive information.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unrestricted File Upload: Attackers can exploit the vulnerability by uploading malicious files, such as web shells, to the web server.
• Remote Code Execution (RCE): Once a web shell is uploaded, attackers can execute arbitrary commands on the server, leading to full control over the system.
• Data Exfiltration: Attackers can use the uploaded web shell to exfiltrate sensitive data from the server.
• Persistent Access: The web shell can provide persistent access to the server, allowing attackers to maintain control even after initial detection.

Exploitation Methods:

• Direct Upload: Attackers can directly upload a web shell through the vulnerable file upload functionality.
• Phishing and Social Engineering: Attackers may use phishing techniques to trick users into uploading malicious files.
• Automated Scanning: Attackers can use automated tools to scan for vulnerable versions of WP VR and exploit the vulnerability.

3. Affected Systems and Software Versions
