CVE-2025-49223: CWE-1321 Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in NAVER billboard.js
billboard.js before 3.15.1 was discovered to contain a prototype pollution via the function generate, which could allow attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties.
AI Analysis
Technical Summary
CVE-2025-49223 is a critical security vulnerability identified in the billboard.js library, a JavaScript charting library maintained by NAVER. The vulnerability is categorized under CWE-1321, which refers to Improperly Controlled Modification of Object Prototype Attributes, commonly known as prototype pollution. This flaw exists in versions of billboard.js prior to 3.15.1 and is specifically triggered via the 'generate' function. Prototype pollution occurs when an attacker is able to inject or modify properties on an object's prototype, which can lead to unexpected behavior in the application. In this case, an attacker can exploit this vulnerability to inject arbitrary properties into the JavaScript object prototype chain. This manipulation can result in arbitrary code execution or cause a Denial of Service (DoS) condition by corrupting the application state or triggering errors. The vulnerability has a CVSS v3.1 base score of 9.8, indicating a critical severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reveals that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality, integrity, and availability to a high degree. Although no known exploits are currently reported in the wild, the potential for severe impact is significant given the nature of the vulnerability and the widespread use of billboard.js in web applications for data visualization. The lack of affected version details suggests that all versions before 3.15.1 are vulnerable, emphasizing the importance of upgrading to the patched release. This vulnerability can be leveraged by attackers to compromise web applications that utilize billboard.js, potentially leading to full system compromise or service disruption.
Potential Impact
For European organizations, the impact of CVE-2025-49223 can be substantial, especially for those relying on web applications that incorporate billboard.js for data visualization. Exploitation could lead to unauthorized access to sensitive data (confidentiality breach), manipulation or corruption of data visualizations (integrity breach), and disruption of services (availability breach). Sectors such as finance, healthcare, government, and critical infrastructure that depend on accurate and reliable data representation are particularly at risk. The ability to execute arbitrary code remotely without authentication means attackers could pivot to deeper network penetration or deploy ransomware or other malware. Additionally, the DoS potential could interrupt business operations, causing financial loss and reputational damage. Given the criticality and ease of exploitation, European organizations must prioritize addressing this vulnerability to maintain compliance with data protection regulations such as GDPR, which mandates safeguarding personal data against unauthorized access and service interruptions.
Mitigation Recommendations
European organizations should take the following specific mitigation steps: 1) Immediately identify all instances of billboard.js in their web applications and verify the version in use. 2) Upgrade all affected instances to version 3.15.1 or later, where the vulnerability is patched. 3) If immediate upgrade is not feasible, implement temporary mitigations such as input validation and sanitization to prevent malicious payloads from reaching the 'generate' function. 4) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the risk of code injection. 5) Conduct thorough code reviews and penetration testing focusing on prototype pollution vectors in JavaScript components. 6) Monitor application logs and network traffic for unusual activity indicative of exploitation attempts. 7) Educate development teams about prototype pollution risks and secure coding practices to prevent similar vulnerabilities. 8) Maintain an inventory of third-party libraries and establish a patch management process to ensure timely updates.
