CVE-2024-1519 is a stored cross-site scripting vulnerability affecting the Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress WordPress plugin developed by collizo4sky. The vulnerability exists due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'name' parameter. This flaw allows unauthenticated attackers to inject arbitrary JavaScript code into pages rendered by the plugin, which will then execute in the browsers of users who visit the infected member listing page. The attack vector requires the member listing page to be active and styled with the Gerbera theme, which is a prerequisite for the malicious payload to be triggered. Because the vulnerability is stored XSS, the malicious script persists in the plugin's data store and affects all users who access the compromised page. The vulnerability impacts all versions up to and including 4.14.4. The CVSS 3.1 base score of 6.5 reflects that the attack can be performed remotely without authentication or user interaction, with low complexity and moderate impact on confidentiality and integrity. The vulnerability does not affect availability. No public exploit code or active exploitation has been reported yet. The root cause is a failure to properly sanitize user-supplied input and escape output in the plugin's web page generation logic, violating CWE-79 standards. This vulnerability is critical for websites relying on this plugin for membership management, ecommerce, or user registration, as it can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of users.

The impact of CVE-2024-1519 is significant for organizations using the affected WordPress plugin, especially those managing memberships, ecommerce, or user registrations. Successful exploitation allows attackers to execute arbitrary scripts in the context of users' browsers, potentially leading to credential theft, session hijacking, unauthorized actions, or distribution of malware. This can compromise user accounts, damage organizational reputation, and lead to data breaches. Since the vulnerability is exploitable without authentication or user interaction, it poses a high risk of automated attacks and widespread exploitation once public exploits emerge. The requirement for the Gerbera theme and an active member listing page limits the attack surface but does not eliminate risk for affected sites. Organizations with large user bases or sensitive data processed through this plugin are at higher risk. Additionally, compromised user accounts can be leveraged for further attacks within the organization or against third parties. The vulnerability does not impact system availability directly but can cause indirect operational disruptions due to incident response and remediation efforts.

To mitigate CVE-2024-1519, organizations should immediately update the Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin to a version that addresses this vulnerability once available. Until a patch is released, administrators should disable or restrict access to the member listing page, especially if using the Gerbera theme, to prevent triggering the stored XSS payload. Implementing a Web Application Firewall (WAF) with rules to detect and block malicious script injections targeting the 'name' parameter can reduce risk. Conduct a thorough audit of user-generated content in the plugin's data store to identify and remove any injected scripts. Enforce strict Content Security Policy (CSP) headers to limit script execution sources and reduce the impact of potential XSS attacks. Educate users and administrators about the risks of XSS and monitor logs for suspicious activity related to the plugin. Regularly back up website data and configurations to enable recovery in case of compromise. Finally, consider isolating or sandboxing the plugin's functionality to limit the scope of potential attacks.
