Overview
A severe vulnerability, designated as CVE-2025-47452, has been discovered in the RexTheme WP VR view plugin. The vulnerability allows for unrestricted upload of files with dangerous types, posing a significant threat to the security and integrity of websites using this software. This issue is particularly critical as it enables attackers to upload a web shell to a web server, granting them extensive control over the server and potentially leading to system compromise or data leakage.

How the Exploit Works
The exploit works by taking advantage of the unrestricted file upload vulnerability in RexTheme WP VR. Essentially, an attacker can upload a malicious file, typically a web shell, to the web server. The web shell runs commands directly on the server as if the attacker is locally executing them, thereby providing the attacker with control over the server. This could lead to further compromise of the system or data leakage.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited using a HTTP POST request to upload a malicious web shell:
POST /wpvr_upload/ HTTP/1.1
Host: target.example.com
Content-Type: application/php
{ "file": "web_shell.php" }In this example, the attacker is sending a POST request to the vulnerable endpoint (wpvr_upload) with a PHP web shell file (web_shell.php). If the server is vulnerable, it will accept the file and store it on the server, giving the attacker the ability to execute commands on the server remotely.
Mitigation and Remediation
As of now, the best method to mitigate this vulnerability is to apply the vendor-provided patch. If the patch is not available or cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by blocking or alerting on attempts to exploit this vulnerability. However, these are only temporary measures and the vendor’s patch should be applied as soon as possible to fully mitigate the risk posed by CVE-2025-47452.
