Prototype Pollution Vulnerability in Kibana by Elastic

CVE-2025-25014

What is CVE-2025-25014?

CVE-2025-25014 is a prototype pollution vulnerability found in Kibana, a popular open-source analytics and visualization platform developed by Elastic. Kibana is commonly used to visualize and analyze data from various sources, including Elasticsearch, providing powerful tools for data exploration. This vulnerability allows attackers to manipulate the prototype of objects in JavaScript, which can lead to arbitrary code execution when crafted HTTP requests target the machine learning and reporting endpoints of the system. The implications of this flaw are severe, as it could enable threat actors to execute malicious code on the server, potentially compromising sensitive data or system integrity. Organizations utilizing Kibana are therefore at a significant risk if this vulnerability is left unaddressed, especially in environments where machine learning functionalities are heavily leveraged.

Potential impact of CVE-2025-25014

1. Arbitrary Code Execution: Attackers can exploit the vulnerability to execute arbitrary code on the affected server, leading to complete control of the system. This can facilitate data breaches or unauthorized alterations of crucial information.

2. Data Integrity Compromise: With the ability to execute malicious code, intruders could manipulate or corrupt the data processed or stored by Kibana, impacting analytics and business-critical insights derived from this data.

3. Wider System Compromise: As Kibana often integrates with other enterprise tools and data sources, a successful exploitation of this vulnerability may lead to a cascade of additional vulnerabilities, allowing further attacks within the organizational infrastructure.
