CVE-2022-1900 in Copify Plugin
Summary
by MITRE • 06/13/2022
The Copify plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3.0. This is due to missing nonce validation on the CopifySettings page. This makes it possible for unauthenticated attackers to update the plugins settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Copify plugin for WordPress represents a significant security vulnerability through its implementation of Cross-Site Request Forgery (CSRF) protection flaws in versions up to and including 1.3.0. This vulnerability stems from the absence of proper nonce validation mechanisms within the CopifySettings page functionality, creating an exploitable condition that undermines the fundamental security principles of web application integrity. The flaw specifically targets the plugin's administrative configuration interface, where legitimate users with administrative privileges could unknowingly execute malicious actions without proper authentication verification.
This CSRF vulnerability operates through the manipulation of legitimate web requests that appear to originate from authenticated users, exploiting the trust relationship between the web application and its users. The absence of nonce validation means that an attacker can craft malicious requests that, when executed by an authenticated administrator, will modify plugin settings without requiring any authentication credentials. The vulnerability's impact is amplified by the fact that it affects unauthenticated attackers who can leverage social engineering techniques to trick administrators into executing these malicious requests, making the attack vector particularly insidious.
The operational consequences of this vulnerability extend beyond simple configuration changes to potentially enable more severe security breaches. When an attacker successfully exploits this CSRF flaw, they can modify plugin settings to inject malicious web scripts, potentially leading to persistent cross-site scripting attacks, unauthorized data access, or even complete administrative compromise of the affected WordPress installation. The vulnerability's classification aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications, and demonstrates the critical importance of proper request validation and authentication mechanisms in plugin development.
The attack scenario typically involves an administrator visiting a malicious website or clicking on a crafted link that automatically submits a forged request to the vulnerable Copify plugin settings page. Without proper nonce validation, the WordPress application processes these requests as legitimate administrative actions, allowing the attacker to modify configuration parameters and potentially inject malicious code. This vulnerability directly maps to ATT&CK technique T1059.007, which covers scripting through web shells, as the injected malicious scripts could provide persistent access to the compromised system.
Security mitigation strategies should prioritize immediate plugin updates to versions that implement proper nonce validation and CSRF protection mechanisms. Administrators should also implement additional security measures such as monitoring for unauthorized configuration changes, employing web application firewalls, and conducting regular security audits of installed plugins. The vulnerability underscores the necessity of following secure coding practices, particularly the implementation of cryptographic nonces for all administrative actions, as recommended by the OWASP Top Ten security framework. Organizations should also consider implementing principle of least privilege access controls and regular security training for administrators to reduce the risk of successful social engineering attacks that exploit such vulnerabilities.
