CVE-2025-5817: Amazon Products To WooCommerce SSRF Flaw

CVE-2025-5817 Overview

The Amazon Products to WooCommerce plugin for WordPress contains a Server-Side Request Forgery (SSRF) vulnerability in all versions up to and including 1.2.7. The vulnerability exists in the wcta2w_get_urls() function, which allows unauthenticated attackers to make web requests to arbitrary locations originating from the web application. This can be exploited to query and modify information from internal services that would otherwise be inaccessible from the external network.

Critical Impact

Unauthenticated attackers can leverage this SSRF vulnerability to access internal network resources, potentially exposing sensitive internal services, metadata endpoints, and backend infrastructure typically protected from external access.

Affected Products

• Amazon Products to WooCommerce plugin versions up to and including 1.2.7
• WordPress sites running affected plugin versions
• suhailahmad64 amazon_products_to_woocommerce

Technical Details for CVE-2025-5817

Vulnerability Analysis

This Server-Side Request Forgery (SSRF) vulnerability (CWE-918) in the Amazon Products to WooCommerce plugin enables attackers to abuse the server's ability to make HTTP requests. The vulnerable wcta2w_get_urls() function fails to properly validate or restrict user-supplied URLs before making server-side requests. Since the vulnerability is accessible without authentication, any remote attacker can exploit it without needing valid credentials on the WordPress site.

The impact of this SSRF vulnerability extends beyond simple information disclosure. Attackers can use the compromised server as a proxy to scan internal networks, access cloud metadata services (such as AWS EC2 metadata at 169.254.169.254), interact with internal APIs, and potentially modify data on internal services. The changed scope indicated by the vulnerability assessment means that the compromised component can affect resources beyond its security authority.

Root Cause

The root cause of this vulnerability is improper input validation in the wcta2w_get_urls() function located in inc/urls-ajax.php. The function accepts user-controlled URL parameters and makes HTTP requests to those URLs without adequate validation to ensure the target is a legitimate external resource. This lack of URL allowlisting or blocklisting allows attackers to specify internal IP addresses, localhost references, or cloud metadata endpoints as request targets.

Attack Vector

The attack vector is network-based and requires no user interaction or authentication. An attacker can craft malicious requests to the vulnerable AJAX endpoint, specifying internal network addresses or cloud metadata URLs as the target. The WordPress server will then make requests on the attacker's behalf, returning potentially sensitive data from internal services.

The vulnerability can be exploited to:

• Access internal network services not exposed to the internet
• Retrieve cloud provider metadata containing sensitive credentials
• Scan internal network infrastructure
• Interact with internal APIs to read or modify data
• Bypass firewall restrictions by using the server as a trusted intermediary

Detection Methods for CVE-2025-5817

Indicators of Compromise

• Unusual outbound HTTP requests from the WordPress server to internal IP ranges (e.g., 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
• Server requests targeting cloud metadata endpoints such as 169.254.169.254
• AJAX requests to the wcta2w_get_urls endpoint with suspicious URL parameters
• Unexpected network traffic patterns originating from the web server to internal services

Detection Strategies

• Monitor web server access logs for requests to the vulnerable AJAX endpoint with internal IP addresses or localhost references
• Implement network monitoring to detect outbound requests from the web server to internal network ranges
• Deploy Web Application Firewall (WAF) rules to block SSRF attack patterns targeting WordPress plugins
• Review WordPress plugin activity logs for unusual API interactions

Monitoring Recommendations

• Configure alerting for outbound connections from web servers to internal network segments
• Monitor DNS queries from web servers for internal hostname resolution attempts
• Implement egress filtering and logging at the network perimeter
• Enable detailed logging for WordPress AJAX requests to capture potential exploitation attempts

How to Mitigate CVE-2025-5817

Immediate Actions Required

• Update the Amazon Products to WooCommerce plugin to a version newer than 1.2.7 if a patched version is available
• If no patch is available, deactivate and remove the vulnerable plugin until a fix is released
• Implement network-level egress filtering to prevent the web server from accessing internal resources
• Deploy WAF rules to block SSRF attack patterns

Patch Information

Check the Wordfence Vulnerability Report for the latest patch status and updates from the plugin developer. Organizations should monitor for plugin updates that address the vulnerable wcta2w_get_urls() function.

Workarounds

• Disable the Amazon Products to WooCommerce plugin until a patch is available
• Implement egress filtering at the network level to restrict outbound connections from the web server
• Configure firewall rules to block requests to internal IP ranges and cloud metadata endpoints from the WordPress application
• Use a reverse proxy or WAF to inspect and block requests containing internal network addresses

# Configuration example - Block internal IP ranges in wp-config.php or server firewall
# Add to .htaccess to block direct access to vulnerable endpoint
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} wcta2w_get_urls [NC]
RewriteRule .* - [F,L]
</IfModule>
