CVE-2024-1782 identifies a reflected Cross-Site Scripting (XSS) vulnerability in the Blue Triad EZAnalytics plugin for WordPress, versions up to and including 1.0. The vulnerability stems from insufficient sanitization and escaping of the 'bt_webid' parameter during web page generation, categorized under CWE-79. An unauthenticated attacker can craft a malicious URL containing a payload in the 'bt_webid' parameter, which when visited by a user, executes arbitrary JavaScript in the context of the vulnerable site. This reflected XSS does not require authentication but does require user interaction, such as clicking a link. The vulnerability affects confidentiality and integrity by potentially allowing theft of session cookies, user credentials, or performing actions on behalf of the user. The CVSS 3.1 score of 6.1 reflects a network attack vector, low attack complexity, no privileges required, but user interaction is necessary, and the scope is changed due to potential impact on other components via script execution. No patches or official fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability is significant for websites using this plugin, especially those with high user interaction or sensitive data.

The primary impact of CVE-2024-1782 is the potential compromise of user confidentiality and integrity on affected WordPress sites using the Blue Triad EZAnalytics plugin. Attackers can steal session tokens, hijack accounts, or perform unauthorized actions by injecting malicious scripts. This can lead to phishing attacks, data theft, or unauthorized transactions. While availability is not directly affected, the reputational damage and loss of user trust can be significant. Organizations relying on this plugin for analytics may face increased risk of targeted attacks, especially if their users have elevated privileges or access to sensitive information. The vulnerability's ease of exploitation (no authentication needed) increases the risk, particularly for sites with high traffic or users prone to clicking untrusted links. The lack of known exploits in the wild suggests limited current active exploitation but does not preclude future attacks once exploit code becomes publicly available.

To mitigate CVE-2024-1782, organizations should immediately assess the presence of the Blue Triad EZAnalytics plugin on their WordPress sites and disable or remove it if possible until a patch is available. If removal is not feasible, implement Web Application Firewall (WAF) rules to detect and block malicious payloads targeting the 'bt_webid' parameter. Employ Content Security Policy (CSP) headers to restrict script execution sources, reducing the impact of injected scripts. Educate users to avoid clicking suspicious links, especially those that appear to originate from untrusted sources. Monitor web server logs for unusual requests containing suspicious 'bt_webid' parameter values. Developers maintaining the plugin should prioritize releasing a patch that properly sanitizes and escapes user input. Additionally, consider implementing input validation libraries and output encoding functions consistent with OWASP guidelines. Regularly update WordPress core and plugins to minimize exposure to known vulnerabilities.
