Compliance Impact

The vulnerability allows unauthenticated remote code execution, enabling attackers to upload and execute arbitrary PHP files on the server. This can lead to unauthorized access and control over the affected system.

Such unauthorized access and potential data breaches could result in non-compliance with common standards and regulations like GDPR and HIPAA, which require protection of sensitive data and secure system access.

However, the provided information does not explicitly describe the direct impact on compliance with these standards.

Executive Summary

The WordPress Augmented-Reality plugin contains a remote code execution vulnerability in its elFinder connector. This flaw allows unauthenticated attackers to send specially crafted POST requests to the connector.minimal.php endpoint using mkfile and put commands. By doing so, attackers can create and upload malicious PHP files into the file_manager directory on the server and then execute these files remotely.

Impact Analysis

This vulnerability can have severe impacts as it allows attackers to execute arbitrary PHP code on your server without any authentication. This means an attacker can potentially take full control of the affected WordPress site, upload malicious scripts, manipulate data, deface the website, or use the server as a foothold for further attacks.

Detection Guidance

This vulnerability can be detected by checking for the presence of the vulnerable endpoint and attempting to identify unauthorized file uploads or executions through it.

Specifically, you can scan your WordPress installation for the existence of the file path `/wp-content/plugins/augmented-reality/vendor/elfinder/php/connector.minimal.php`.

To detect exploitation attempts or verify vulnerability, you can use HTTP POST requests targeting the `connector.minimal.php` endpoint with `mkfile` and `put` commands to see if arbitrary PHP files can be created or executed.

• Use curl or similar tools to send crafted POST requests to the endpoint, for example:
• curl -X POST -d 'cmd=mkfile&name=test.php' https://yourwordpresssite.com/wp-content/plugins/augmented-reality/vendor/elfinder/php/connector.minimal.php
• curl -X POST -d 'cmd=put&target=file_manager/test.php&content=<?php phpinfo(); ?>' https://yourwordpresssite.com/wp-content/plugins/augmented-reality/vendor/elfinder/php/connector.minimal.php

Additionally, monitoring web server logs for unusual POST requests to this endpoint or unexpected PHP file creations in the `file_manager` directory can help detect exploitation.

There is also an exploit script available that automates scanning for vulnerable sites and uploading shells, which can be used in a controlled environment to verify vulnerability.

Mitigation Strategies

Immediate mitigation steps include disabling or removing the vulnerable WordPress Augmented-Reality plugin, especially versions 7.0 and below.

If removal is not immediately possible, restrict access to the vulnerable endpoint `/wp-content/plugins/augmented-reality/vendor/elfinder/php/connector.minimal.php` by implementing firewall rules or web server access controls to block unauthenticated POST requests.

Monitor your server for any suspicious PHP files in the `file_manager` directory and remove any unauthorized files.

Apply any available patches or updates from the plugin developer as soon as they are released.

Consider implementing web application firewall (WAF) rules to detect and block exploitation attempts targeting this vulnerability.
