CVE-2024-1782 in Blue Triad EZAnalytics Plugin
Summary
by MITRE • 03/05/2024
The Blue Triad EZAnalytics plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'bt_webid' parameter in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Blue Triad EZAnalytics plugin for WordPress represents a significant security vulnerability through its reflected cross-site scripting flaw identified as CVE-2024-1782. This vulnerability affects all versions up to and including version 1.0 of the plugin, creating a persistent threat vector that exploits insufficient input sanitization and output escaping mechanisms. The vulnerability specifically targets the 'bt_webid' parameter within the plugin's functionality, allowing malicious actors to inject arbitrary web scripts that can execute in the context of a victim's browser session.
The technical nature of this vulnerability stems from the plugin's failure to properly validate and sanitize user input received through the bt_webid parameter. When this parameter is processed without adequate sanitization measures, it creates an opening for attackers to inject malicious scripts that can be executed when the page containing the reflected payload is loaded. This type of vulnerability falls under CWE-79 which specifically addresses cross-site scripting flaws in web applications. The vulnerability operates at the web application layer where user-supplied data is directly incorporated into web page output without proper encoding or validation.
The operational impact of this vulnerability is particularly concerning given that it affects an unauthenticated attack vector, meaning that any user visiting a page containing the malicious payload could be compromised without requiring any authentication credentials or privileged access. This makes the vulnerability highly exploitable in real-world scenarios where attackers can craft malicious links or pages that, when clicked by unsuspecting users, would execute the injected scripts. The reflected nature of the XSS means that the malicious payload is reflected back to the user through the web application's response, making it difficult to detect and prevent without proper input validation.
Security professionals should recognize this vulnerability as a critical risk that aligns with ATT&CK technique T1566.001 which covers phishing with malicious attachments and links. The vulnerability enables attackers to perform session hijacking, credential theft, and other malicious activities by exploiting the trust relationship between the user and the vulnerable WordPress site. The attack chain typically involves crafting a malicious URL containing the XSS payload and persuading victims to click on it, making social engineering a critical component of the exploitation strategy.
Mitigation strategies should focus on immediate plugin updates to the latest available version where the vulnerability has been patched, though users should verify that the update properly addresses the specific sanitization issues. Additionally, implementing proper input validation and output escaping measures within the plugin's codebase would prevent future occurrences of similar issues. Organizations should also consider implementing content security policies to limit the execution of unauthorized scripts, and conducting regular security audits of third-party plugins to identify potential vulnerabilities. The vulnerability highlights the importance of proper security testing and validation of all user inputs, particularly in web applications where user interaction is expected.
