Executive Summary

CVE-2025-37729 is a critical vulnerability in Elastic Cloud Enterprise (ECE) versions 2.5.0 through 3.8.1 and 4.0.0 through 4.0.1 caused by improper neutralization of special elements in the Jinjava template engine. This flaw allows a malicious actor with administrative access to the ECE admin console and a deployment with the Logging+Metrics feature enabled to execute arbitrary code by submitting specially crafted payloads in deployment plans. These payloads can be injected and executed, and the results can be exfiltrated via ingested logs. [1]

Impact Analysis

This vulnerability can have a severe impact as it allows an attacker with admin privileges to execute arbitrary code remotely, leading to full compromise of the affected system. The attacker can exfiltrate sensitive information and issue unauthorized commands, affecting confidentiality, integrity, and availability of the system. [1]

Detection Guidance

This vulnerability can be detected by monitoring request logs for malicious payloads that include specific indicators such as 'payload.name : int3rpr3t3r' or 'payload.name : forPath'. You can use search queries on your logging system to find these patterns. For example, if using Elasticsearch or Kibana, you might run a query like: (payload.name : int3rpr3t3r OR payload.name : forPath) to identify suspicious activity related to this vulnerability. [1]

Mitigation Strategies

The immediate mitigation step is to upgrade Elastic Cloud Enterprise (ECE) to versions 3.8.2 or 4.0.2, which contain fixes for this vulnerability. There are no workarounds available for users who cannot upgrade, so applying the update is critical to prevent exploitation. [1]
