Overview<\/strong><\/p>\n

In the world of cybersecurity, the vulnerability CVE-2025-25014 is a significant threat to the integrity and security of systems running Kibana. This vulnerability is a prototype pollution flaw, an insidious type of vulnerability that can lead to a variety of detrimental security impacts. The affected software<\/a>, Kibana, is a popular open-source data visualization and exploration tool used for log and time-series analytics, application monitoring, and operational intelligence use cases. The vulnerability, if exploited, allows an attacker to execute arbitrary code<\/a> via carefully crafted HTTP requests to machine learning and reporting endpoints. It is thus of paramount importance for all users of Kibana to understand this vulnerability<\/a> and to apply mitigation measures.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-25014
\nSeverity: Critical (9.1 CVSS score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: System Compromise<\/a>, Data Leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Kibana | All versions prior<\/a> to the latest patched release<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The CVE-2025-25014 vulnerability involves a prototype pollution<\/a> flaw in Kibana. Prototype pollution is essentially a vulnerability caused when an attacker is able to manipulate<\/a> the prototype of a JavaScript object, which can lead to the addition or modification of existing properties that will then exist on all objects.
\nIn the context of this vulnerability, an attacker sends a specially crafted HTTP request to the machine learning and reporting<\/a> endpoints of Kibana. This request can manipulate the prototype of an object, leading to unexpected behavior<\/a> in the application. The consequence of this vulnerability is arbitrary code<\/a> execution, which means that an attacker can run any command of their choice on the affected system.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The following is a conceptual example of how an HTTP request exploiting this vulnerability<\/a> might look. This is pseudocode and is for illustrative purposes only.<\/p>\n

POST \/api\/machine_learning\/anomalies HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"__proto__\": { \"exec\": \"rm -rf \/ --no-preserve-root\" } }<\/code><\/pre>\n
In this example, the “__proto__” object is being manipulated to execute a dangerous command that could wipe the server’s file system<\/a>. This clearly illustrates the severity of this vulnerability<\/a> and underscores the importance of mitigating it effectively.<\/p>\n","protected":false},"excerpt":{"rendered":"
