The vulnerability CVE-2024-49277 represents a critical cross-site scripting flaw within the UltraAddons Elementor Lite plugin, specifically impacting versions through 2.0.2. This weakness falls under the CWE-79 category of Cross-Site Scripting, where improper input sanitization during web page generation creates opportunities for malicious code injection. The vulnerability manifests as a stored XSS attack vector, meaning that malicious scripts can be permanently stored on the server and subsequently executed whenever affected pages are loaded by unsuspecting users. The issue stems from inadequate validation and sanitization of user-supplied input that gets processed and rendered within the plugin's output generation mechanisms.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious input through the plugin's interface or API endpoints, which are then stored in the system's database without proper sanitization. When other users access pages that display this stored content, their browsers execute the injected malicious scripts within the context of the vulnerable website. This creates a persistent threat where the malicious code can perform actions such as stealing user sessions, defacing pages, or redirecting users to malicious sites. The stored nature of this XSS vulnerability makes it particularly dangerous as the attack vector persists until manually removed from the system.
From an operational standpoint, this vulnerability poses significant risks to websites utilizing the UltraAddons Elementor Lite plugin, particularly those that allow user-generated content or administrative input through the plugin's interface. The attack surface expands when considering that Elementor is a widely-used page builder plugin, and UltraAddons extends its functionality with additional widgets and features. Attackers could leverage this vulnerability to compromise user accounts, steal sensitive information, or manipulate website content. The impact extends beyond individual site compromise to potentially affect entire user bases that rely on the plugin's functionality, especially in environments where multiple users contribute content or where administrators have elevated privileges within the system.
Mitigation strategies for CVE-2024-49277 should prioritize immediate patching of the UltraAddons Elementor Lite plugin to versions that address the XSS vulnerability. System administrators should implement input validation and output encoding mechanisms to prevent malicious content from being stored or executed within the application. The principle of least privilege should be enforced, limiting administrative access to plugin configurations and user input fields. Additionally, implementing content security policies and regular security scanning of plugin components can help detect and prevent similar vulnerabilities. Organizations should also consider monitoring for suspicious user activities and implementing web application firewalls to detect and block potential XSS attack attempts. The ATT&CK framework categorizes this vulnerability under T1059.005 - Command and Scripting Interpreter: PowerShell, and T1566.001 - Phishing: Spearphishing Attachment, as attackers may leverage this vulnerability to deliver malicious payloads through compromised user accounts or automated attack vectors.
