CVE-2025-32576
Remediation/Mitigation Strategy: CVE-2025-32576
Vulnerability: Cross-Site Request Forgery (CSRF)
Affected Software: Agence web Eoxia - Montpellier WP shop Plugin
Affected Versions: Versions up to and including 2.6.0
Description: The plugin is vulnerable to a Cross-Site Request Forgery (CSRF) attack, allowing an attacker to potentially upload a web shell to the server. A successful CSRF attack leverages a legitimate user’s authenticated session to execute unauthorized actions on their behalf. In this case, an attacker could trick an administrator into clicking a malicious link or visiting a compromised website, which would then trigger the plugin to upload a web shell. Web shells provide attackers with remote access and control over the affected web server.
Severity: Critical (CVSS Score: 9.6)
Known Exploit: The vulnerability can be exploited by crafting a malicious HTML page or URL that, when visited by an authenticated administrator of the WordPress site using the vulnerable WP Shop plugin, would trigger the upload functionality without the administrator’s direct knowledge or consent. This crafted request bypasses normal CSRF protections, leading to the unintended upload of a web shell.
Remediation Steps:
Update the Plugin: The primary and most effective solution is to update the WP Shop plugin to a version beyond 2.6.0. Contact the plugin vendor (Agence web Eoxia - Montpellier) for patched versions or seek alternative plugins that address the same functionality. This is the highest priority action.
Disable the Plugin (Temporary Mitigation): If an immediate update is not available, temporarily disable the WP Shop plugin to prevent exploitation of the vulnerability until a patch can be applied. This will remove the attack vector. Log into your WordPress admin panel, navigate to the “Plugins” section, locate the “WP Shop” plugin, and deactivate it.
Implement CSRF Protection Measures: Even after updating, consider implementing or verifying the existence of robust CSRF protection mechanisms for all sensitive actions within the plugin (or WordPress in general) including those related to file uploads. This could involve:
Synchronizer Token Pattern: Ensure that all forms and AJAX requests related to sensitive actions include a unique, unpredictable token that is validated on the server side. This token should be unique per user session and regenerated frequently.
Double-Submit Cookie Pattern: Use a cookie to store a random value and require that value to be submitted in the request body or header. The server compares the cookie value with the submitted value.
Web Application Firewall (WAF): Implement a Web Application Firewall (WAF) and configure it with rulesets designed to detect and block CSRF attacks. The WAF can provide an additional layer of defense even if the plugin itself has vulnerabilities. Ensure the WAF is regularly updated with the latest signature rules.
Monitor Web Server Logs: Closely monitor web server logs for any suspicious activity, such as attempts to access web shells or unauthorized file uploads. Look for patterns indicative of exploitation attempts.
User Training: Educate WordPress administrators and users about the risks of CSRF attacks and best practices for avoiding them, such as:
- Being cautious about clicking on links in emails or websites, especially if they are from untrusted sources.
- Logging out of WordPress when not actively using the admin panel.
- Keeping their web browsers and operating systems up to date.
- Using strong, unique passwords.
Regular Security Audits: Conduct regular security audits of the WordPress installation and all installed plugins to identify and address potential vulnerabilities. Consider using security scanning tools to automate the audit process.
Principle of Least Privilege: Grant users only the minimum level of access necessary to perform their duties. Avoid granting administrator privileges to users who do not require them. Limit the number of users with administrator access.
