CVE-2025-7812: Video Share VOD WordPress CSRF Vulnerability

CVE-2025-7812 Overview

CVE-2025-7812 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Video Share VOD – Turnkey Video Site Builder Script plugin for WordPress in all versions up to and including 2.7.6. The vulnerability stems from missing or incorrect nonce validation on the adminExport() function, allowing unauthenticated attackers to update plugin settings and potentially execute remote code when the "Server command execution" setting is enabled. Successful exploitation requires social engineering to trick a site administrator into clicking a malicious link.

Critical Impact

Unauthenticated attackers can chain CSRF with Remote Code Execution when server command execution is enabled, potentially leading to full site compromise.

Affected Products

• Video Share VOD – Turnkey Video Site Builder Script plugin for WordPress versions ≤ 2.7.6
• WordPress installations using the vulnerable plugin versions
• Websites with "Server command execution" setting enabled are at highest risk

Technical Details for CVE-2025-7812

Vulnerability Analysis

This vulnerability is classified as CWE-352 (Cross-Site Request Forgery). The adminExport() function in the Video Share VOD plugin fails to properly implement WordPress nonce verification, which is a critical security mechanism designed to prevent unauthorized requests from being processed. Without proper nonce validation, the function cannot distinguish between legitimate administrative actions initiated by authenticated administrators and malicious requests crafted by attackers.

The attack surface is significantly expanded when the plugin's "Server command execution" setting is enabled. In this configuration, an attacker who successfully exploits the CSRF vulnerability can not only modify plugin settings but can also achieve remote code execution on the underlying server. This escalation from CSRF to RCE represents a severe security risk for affected WordPress installations.

Root Cause

The root cause of this vulnerability lies in the insufficient implementation of WordPress's built-in CSRF protection mechanisms. The adminExport() function either completely omits nonce validation or implements it incorrectly, failing to call wp_verify_nonce() or check_admin_referer() before processing administrative requests. This oversight allows any request—whether originating from a legitimate administrator session or a forged external source—to be processed by the vulnerable function.

Attack Vector

The attack follows a network-based vector requiring user interaction. An attacker crafts a malicious web page or link containing a forged request targeting the vulnerable adminExport() function. When an authenticated WordPress administrator visits the attacker's page or clicks the malicious link, their browser automatically sends the forged request along with their valid session cookies.

The exploitation flow involves:

1. Attacker identifies a WordPress site running Video Share VOD plugin version 2.7.6 or earlier
2. Attacker creates a malicious page with a hidden form or JavaScript that targets the plugin's administrative endpoint
3. Attacker socially engineers a site administrator to visit the malicious page
4. The administrator's browser submits the forged request with valid session credentials
5. The vulnerable function processes the request, allowing settings modification
6. If "Server command execution" is enabled, arbitrary commands can be executed on the server

The vulnerability mechanism centers on the missing nonce validation in the administrative export functionality. Technical details can be found in the WordPress Plugin Main Code and the WordPress Plugin Options Code.

Detection Methods for CVE-2025-7812

Indicators of Compromise

• Unexpected modifications to Video Share VOD plugin settings without administrator action
• Suspicious referrer headers in web server logs pointing to external domains during plugin configuration changes
• Unauthorized file modifications or new files appearing in WordPress directories
• Server command execution logs showing unexpected activity correlating with plugin usage
• Administrative actions logged without corresponding administrator login sessions

Detection Strategies

• Monitor WordPress admin-ajax.php and plugin administrative endpoints for requests with missing or invalid nonce parameters
• Implement web application firewall (WAF) rules to detect and block CSRF attack patterns targeting WordPress plugins
• Enable and review WordPress audit logging to identify unauthorized settings changes
• Deploy SentinelOne Singularity to detect post-exploitation behaviors such as web shell deployment or suspicious process execution from web server contexts

Monitoring Recommendations

• Configure alerting for plugin settings modifications occurring outside normal administrative workflows
• Monitor server-side command execution patterns, especially those originating from PHP processes
• Review HTTP referrer headers for administrative requests to identify potential CSRF attack attempts
• Implement Content Security Policy (CSP) headers to reduce the attack surface for embedded CSRF attacks

How to Mitigate CVE-2025-7812

Immediate Actions Required

• Update Video Share VOD plugin to the patched version immediately by reviewing the WordPress Plugin Changeset 3348480
• Disable the "Server command execution" setting in the plugin configuration to reduce the attack surface
• Review recent plugin settings changes to identify any unauthorized modifications
• Implement additional CSRF protections at the web server or WAF level while awaiting patch deployment

Patch Information

The vulnerability has been addressed in plugin updates following version 2.7.6. The security fix implements proper nonce validation on the adminExport() function to prevent unauthorized requests. Site administrators should update through the WordPress plugin update mechanism or download the latest version from the WordPress plugin repository. For detailed information about the vulnerability and remediation, refer to the Wordfence Vulnerability Report.

Workarounds

• Disable the Video Share VOD plugin entirely until a patch can be applied in production
• Restrict administrative access to trusted IP addresses only using .htaccess or firewall rules
• Disable the "Server command execution" feature in plugin settings to prevent RCE even if CSRF is successful
• Implement additional CSRF protection using security plugins such as Wordfence or Sucuri as a defense-in-depth measure
• Train administrators to avoid clicking unfamiliar links while logged into WordPress admin sessions

# Example: Restrict WordPress admin access by IP in .htaccess
<Files wp-admin>
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.100
    Allow from 10.0.0.0/24
</Files>
