CVE-2025-32576: WP Shop CSRF Vulnerability

CVE-2025-32576 Overview

CVE-2025-32576 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the WP shop WordPress plugin developed by Agence web Eoxia - Montpellier. This vulnerability allows attackers to upload a web shell to a web server by exploiting the lack of proper CSRF token validation in file upload functionality. The issue affects WP shop versions through 2.6.0.

Critical Impact

This vulnerability enables attackers to achieve remote code execution by uploading malicious web shells through CSRF attacks, potentially leading to complete server compromise.

Affected Products

• WP shop WordPress plugin versions up to and including 2.6.0
• WordPress installations running vulnerable WP shop plugin versions

Technical Details for CVE-2025-32576

Vulnerability Analysis

This vulnerability combines Cross-Site Request Forgery (CSRF) with arbitrary file upload capabilities, creating a severe attack chain that can lead to complete server compromise. The WP shop plugin fails to implement proper CSRF token validation on file upload endpoints, allowing attackers to craft malicious requests that authenticated administrators unknowingly execute when visiting attacker-controlled pages.

When successfully exploited, an attacker can upload arbitrary files, including PHP web shells, to the target web server. Once a web shell is in place, the attacker gains the ability to execute arbitrary commands on the server, access sensitive data, modify files, and potentially pivot to other systems within the network. The changed scope indicated by the vulnerability assessment means the impact extends beyond the vulnerable component itself, affecting the confidentiality, integrity, and availability of the entire hosting environment.

Root Cause

The root cause of this vulnerability is the absence of proper Cross-Site Request Forgery protection mechanisms in the WP shop plugin's file upload functionality. WordPress provides built-in nonce verification functions (wp_verify_nonce() and check_admin_referer()) to prevent CSRF attacks, but the vulnerable code paths in WP shop fail to implement these security controls. This allows cross-origin requests to successfully invoke file upload operations without validation of request origin or intent.

Attack Vector

The attack requires user interaction where an authenticated WordPress administrator must visit a malicious webpage or click a crafted link while logged into the affected WordPress site. The attacker hosts a malicious page containing a hidden form or JavaScript that automatically submits a file upload request to the vulnerable WP shop endpoint.

The attack flow proceeds as follows: First, the attacker crafts a malicious HTML page containing a form that targets the vulnerable file upload endpoint with a web shell payload. Second, the attacker tricks an authenticated WordPress administrator into visiting this malicious page. Third, the administrator's browser automatically submits the form, uploading the web shell using the administrator's session cookies. Finally, the attacker accesses the uploaded web shell to execute arbitrary commands on the server.

Due to the network-based attack vector and the requirement for only user interaction (no prior authentication needed by the attacker), this vulnerability is accessible to remote attackers with basic social engineering capabilities.

Detection Methods for CVE-2025-32576

Indicators of Compromise

• Unexpected PHP files appearing in WordPress upload directories or plugin folders
• Web server access logs showing requests to unfamiliar PHP files with command parameters
• Suspicious outbound network connections originating from the web server process
• Modified file timestamps on WordPress core files or plugin directories

Detection Strategies

• Monitor WordPress upload directories for newly created PHP files using file integrity monitoring solutions
• Implement web application firewall rules to detect and block web shell signatures in uploaded content
• Review web server access logs for patterns indicative of web shell usage such as commands being passed via URL parameters
• Deploy endpoint detection and response (EDR) solutions to identify post-exploitation behavior

Monitoring Recommendations

• Enable WordPress audit logging to track administrative actions including file uploads
• Configure alerts for file system changes in the WordPress installation directory
• Monitor for unusual process spawning from the web server parent process
• Implement network monitoring to detect command and control communications

How to Mitigate CVE-2025-32576

Immediate Actions Required

• Audit and remove the WP shop plugin if not essential to business operations until a patched version is available
• Review WordPress upload directories for any suspicious PHP files and remove unauthorized content
• Implement web application firewall rules to block file uploads with executable extensions
• Restrict administrative access to trusted IP addresses where possible

Patch Information

Organizations should monitor the Patchstack vulnerability database for updates regarding patches and remediation guidance for this vulnerability. Until an official patch is released, consider disabling or removing the WP shop plugin entirely.

Workarounds

• Disable the WP shop plugin until a security patch is released by the vendor
• Implement server-side file upload restrictions to block PHP and other executable file types
• Add custom CSRF protection through WordPress hooks if the plugin source code can be modified
• Use a web application firewall to enforce CSRF token validation on administrative endpoints

If the plugin must remain active, administrators can implement additional server-level controls:

# Apache configuration to block PHP execution in uploads directory
# Add to .htaccess in wp-content/uploads/
<FilesMatch "\.php$">
    Order Deny,Allow
    Deny from all
</FilesMatch>
