CVE-2025-25014 is a critical vulnerability affecting Elastic's Kibana, with a CVSS score of 9.1. This vulnerability allows attackers to exploit Prototype pollution, leading to arbitrary code execution through specially crafted HTTP requests targeting machine learning and reporting endpoints. The potential for such exploitation poses significant risks, necessitating immediate action from affected organizations.
The vulnerability is classified as critical due to its high CVSS score, which indicates a severe impact on confidentiality, integrity, and availability. Given that it allows remote code execution, the urgency for organizations to patch Kibana installations is paramount, especially as this can lead to unauthorized access and data manipulation.
Currently, exploitability is marked as critical, and there are known exploits available. Organizations should take immediate steps to secure their environments and prevent potential attacks. The risk to organizations includes unauthorized code execution, which can compromise system integrity.
Organizations should prioritize patching immediately, given the high likelihood of exploitation and the severe impact associated with this vulnerability.
Vulnerability Details
The official description states that a Prototype pollution vulnerability in Kibana leads to arbitrary code execution via crafted HTTP requests to machine learning and reporting endpoints. This vulnerability has been assigned a CVSS score of 9.1, indicating a critical severity level. The affected product is Kibana, developed by Elastic.
The vulnerability was published on May 6, 2025, and is categorized under CWE-1321. Organizations using affected versions must be vigilant in applying recommended patches.
Technical Analysis
The root cause of this vulnerability lies in improper handling of crafted HTTP requests, which can manipulate object prototypes, leading to arbitrary code execution. The attack vector is categorized as NETWORK, with a low attack complexity. Attackers require high privileges to exploit this vulnerability, but no user interaction is necessary.
The impacts on confidentiality, integrity, and availability are all high, given that successful exploitation can lead to complete control over the compromised system.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-25014 is substantial. Organizations relying on Kibana for analytics and reporting are particularly vulnerable, as successful exploitation can lead to unauthorized access and manipulation of sensitive data. The blast radius of this vulnerability is significant, as it can affect not only the Kibana instance but also all interconnected systems and databases.
Urgency assessment indicates that organizations should address this vulnerability in their priority patch cycle. Failure to do so could result in severe consequences, including data breaches and loss of customer trust.
