CVE-2024-13905 in OneStore Sites Plugin
Summary
by MITRE • 02/27/2025
The OneStore Sites plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 0.1.1 via the class-export.php file. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.

The vulnerability identified as CVE-2024-13905 affects the OneStore Sites plugin for WordPress, representing a critical server-side request forgery flaw that has been present in all versions up to and including 0.1.1. This type of vulnerability falls under the Common Weakness Enumeration category CWE-918, which specifically addresses server-side request forgery conditions where an attacker can manipulate the target of a request made by a server. The vulnerability is particularly concerning because it exists in the class-export.php file, which serves as a core component for data export functionality within the plugin. The flaw allows unauthenticated attackers to exploit the plugin's functionality to make web requests to arbitrary locations from the web application's perspective, effectively bypassing normal network security controls and potentially accessing internal services that would otherwise be protected by firewalls or network segmentation.
The operational impact of this vulnerability extends far beyond simple data exfiltration, as it creates a pathway for attackers to probe internal networks and potentially compromise systems that are not directly exposed to the internet. When an attacker leverages this vulnerability, they can craft requests that appear to originate from the vulnerable WordPress installation, allowing them to access internal services such as databases, administrative interfaces, or other internal APIs that may be accessible from the web server hosting the WordPress instance. This capability significantly increases the attack surface and can lead to complete system compromise, especially when internal services are not properly secured or when they contain sensitive information or administrative functions. The vulnerability essentially transforms the WordPress server into an unwitting proxy for attacking internal infrastructure, making it a particularly dangerous flaw in environments where internal network segmentation is not properly enforced.
Mitigation strategies for CVE-2024-13905 should prioritize immediate plugin updates to versions that address the server-side request forgery vulnerability, as this represents the most direct and effective solution. Organizations should also implement network-level restrictions to prevent the WordPress server from making outbound connections to internal services unless absolutely necessary, utilizing firewall rules and network segmentation to limit potential damage. Additionally, implementing proper input validation and sanitization measures within the plugin's codebase can help prevent malicious requests from being processed, while monitoring for unusual outbound network activity can help detect exploitation attempts. From an ATT&CK framework perspective, this vulnerability maps to techniques such as T1071.004 (Application Layer Protocol: DNS) and T1566 (Phishing) as attackers may use the vulnerability to target internal DNS servers or to conduct reconnaissance activities. Security teams should also consider implementing web application firewalls that can detect and block suspicious request patterns that attempt to leverage this type of server-side request forgery vulnerability, providing an additional layer of defense against exploitation attempts.
