CVE-2024-12214 is a reflected cross-site scripting (XSS) vulnerability identified in the WooCommerce HSS Extension for Streaming Video plugin for WordPress, affecting all versions up to and including 3.31. The vulnerability stems from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'videolink' parameter. This flaw allows unauthenticated attackers to inject arbitrary JavaScript code into web pages generated by the plugin. When a victim clicks on a maliciously crafted URL containing the injected script, the script executes in the victim's browser context. This can lead to theft of sensitive information such as cookies or session tokens, manipulation of the DOM, or execution of unauthorized actions on behalf of the user. The vulnerability is exploitable remotely over the network without authentication but requires user interaction (clicking a link). The CVSS v3.1 base score is 6.1, indicating medium severity, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, meaning it is network exploitable with low attack complexity, no privileges required, user interaction needed, scope changed, and impacts confidentiality and integrity but not availability. No patches or known exploits are currently reported, but the risk remains significant due to the widespread use of WooCommerce and WordPress. The vulnerability is categorized under CWE-79, a common web application security weakness related to cross-site scripting.

The primary impact of CVE-2024-12214 is on the confidentiality and integrity of users interacting with affected WordPress sites using the WooCommerce HSS Extension for Streaming Video plugin. Successful exploitation can lead to theft of session cookies, enabling account hijacking, unauthorized actions performed in the context of the victim user, and potential redirection to malicious sites. Although availability is not directly impacted, the loss of trust and potential data breaches can cause reputational damage and financial loss to organizations. E-commerce sites using this plugin for streaming video sales are particularly at risk, as attackers could leverage the vulnerability to compromise customer accounts or inject malicious content affecting multiple users. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in phishing or social engineering campaigns. The vulnerability's network accessibility and lack of authentication requirements increase the attack surface, making it a notable threat for organizations relying on this plugin.

To mitigate CVE-2024-12214, organizations should first check for and apply any official patches or updates released by the plugin vendor once available. In the absence of patches, administrators can implement the following specific measures: 1) Employ a Web Application Firewall (WAF) with rules designed to detect and block reflected XSS attacks targeting the 'videolink' parameter. 2) Sanitize and validate all user-supplied input on the server side, ensuring that the 'videolink' parameter does not contain executable scripts or HTML tags. 3) Implement Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the impact of XSS attacks. 4) Educate users and staff about phishing risks and the dangers of clicking on suspicious links. 5) Monitor web server and application logs for unusual requests containing suspicious payloads in the 'videolink' parameter. 6) Consider temporarily disabling or replacing the vulnerable plugin with alternative solutions until a secure version is available. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and the plugin context.
