Email Verification for WooCommerce is a WooCommerce plugin used by e-commerce websites to verify email addresses during the account registration process. It is commonly employed by online stores running on WordPress to ensure that the customer's email address is valid and belongs to them, providing an additional layer of authentication. This plugin allows webshop owners to automate the email verification process, thus reducing manual effort. The software is favored for its ease of integration within WooCommerce's existing registration workflow, improving the security and integrity of user accounts. Additionally, it helps to maintain a clean and authentic customer database by filtering out fake or mistyped email addresses. It is typically used by businesses seeking to enhance user verification and security in customer account creation.
The Improper Authentication vulnerability occurs when security checks are misconfigured, allowing unauthorized access to restricted resources. In Email Verification for WooCommerce, the vulnerability stems from a loose comparison issue that can lead to authentication bypass. This weakness permits a threat actor to log in as an administrator without proper credentials. Such vulnerabilities present significant risks as they may provide attackers with the same privileges as authenticated users. As a critical flaw, it poses a substantial security threat to e-commerce sites utilizing this plugin. Attackers exploiting this vulnerability could manipulate or access sensitive information, leading to a potential loss of data integrity and confidentiality. Organizations using this plugin are advised to update it promptly to mitigate this risk.
Technical details of the vulnerability indicate a flaw in how the plugin performs authentication checks. Specifically, it involves a loose comparison between user-supplied data and stored authentication data. The vulnerability can be exploited via the URL path on affected web applications, where the parameters 'alg_wc_ev_verify_email' are utilized without strict validation. Attackers can craft specific HTTP requests to gain administrative access, bypassing proper checks. Regex and header matching snippets in the nuclei template indicate the presence of security token verification weaknesses. This lack of strong validation allows attackers to simulate authenticated sessions, impacting system security and user data protection.
When this vulnerability is exploited, attackers can gain unauthorized administrative access to the affected WooCommerce installations. This may enable them to perform actions reserved for administrators, such as modifying user accounts, altering settings, and accessing private business data. Consequently, site reputations may be damaged, customer trust eroded, and financial data exposed. It also opens the potential for further exploitation such as installing backdoors, altering store configurations, or causing denial of service. Moreover, compromised sites may be used as vectors for broader cyber-attacks, affecting both users and the business's operational stability.
