CVE-2024-12239 in PowerPack Lite for Beaver Builder Plugin
Summary
by MITRE • 12/17/2024
The PowerPack Lite for Beaver Builder plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the navigate parameter in all versions up to, and including, 1.3.0.5 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 an administrative user into performing an action such as clicking on a link.

The vulnerability identified as CVE-2024-12239 affects the PowerPack Lite for Beaver Builder WordPress plugin, specifically targeting versions up to and including 1.3.0.5. This represents a critical security flaw that exposes WordPress sites to reflected cross-site scripting attacks, creating potential entry points for malicious actors seeking to compromise administrative accounts. The vulnerability resides in how the plugin handles the navigate parameter, which is processed without adequate input sanitization measures. This weakness allows attackers to inject malicious scripts that can execute in the context of an administrator's browser session, potentially leading to full compromise of the affected WordPress installation.
The technical implementation of this vulnerability stems from insufficient input validation and output escaping mechanisms within the plugin's codebase. When the navigate parameter is passed through the plugin's functionality, it fails to undergo proper sanitization before being rendered in the web page output. This creates a classic reflected XSS vector where malicious payloads are injected into the application's response and subsequently executed by the victim's browser. The vulnerability is particularly concerning because it requires no authentication from the attacker, making it accessible to anyone who can craft a malicious link and entice an administrator to click it. The flaw aligns with CWE-79 which categorizes cross-site scripting vulnerabilities as weaknesses in input validation and output encoding, specifically addressing reflected XSS scenarios where user input is directly echoed back to users without proper sanitization.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with the capability to perform actions that could compromise the entire WordPress installation. An attacker who successfully tricks an administrator into clicking a malicious link could potentially steal session cookies, execute arbitrary commands, modify website content, or even install backdoors. The reflected nature of the vulnerability means that the malicious payload is delivered and executed in a single request cycle, making detection more challenging for security monitoring systems. This type of attack vector is particularly dangerous in enterprise environments where administrative privileges are frequently used and the potential for lateral movement within a network increases significantly. The vulnerability also falls under ATT&CK technique T1566 which describes social engineering tactics used to gain initial access, specifically targeting the manipulation of administrators through deceptive links and payloads.
Mitigation strategies for CVE-2024-12239 should prioritize immediate plugin updates to versions that address the XSS vulnerability, as this represents the most effective defense against the known flaw. Organizations should implement comprehensive input validation measures at the application level, ensuring that all user-supplied parameters undergo strict sanitization before processing. Network-level protections such as web application firewalls can provide additional defense-in-depth measures, though these should not replace proper code-level fixes. Security teams should also conduct thorough user awareness training to help administrators recognize potentially malicious links and avoid clicking on suspicious content. Regular security audits of WordPress plugins and themes are essential to identify similar vulnerabilities, with particular attention to input handling and output escaping mechanisms. The vulnerability demonstrates the critical importance of maintaining up-to-date software components and implementing robust security practices throughout the WordPress ecosystem, as reflected in industry standards such as OWASP Top Ten and NIST cybersecurity guidelines for web application security.
