CVE-2025-25014# **CVE-2025-25014 – Critical Remote Code Execution in Kibana via Prototype Pollution** 🧬
---
## 🛡️ Vulnerability Overview
* **Name:** CVE-2025-25014
* **Type:** Prototype Pollution
* **Impact:** Remote Code Execution (RCE)
* **Affected Software:** Kibana
* **Severity:** Critical (CVSS 9.1 out of 10)
* **Description:** An attacker can send specially crafted HTTP requests to Kibana’s Machine Learning or Reporting APIs, leading to prototype pollution that can result in arbitrary code execution.
---
## 🎯 Affected Versions
* All Kibana versions from **8.3.0 to 8.17.5**
* Also affects **8.18.0** and **9.0.0**
* Only exploitable if **Machine Learning** or **Reporting** features are **enabled**
---
## 🚨 Exploit Details
* Public Proof-of-Concept (PoC) is available.
* Attack requires **high privileges** (authenticated attacker).
* **No user interaction** required.
* Can be exploited **remotely over the network**
---
## ✅ Mitigation & Fixes
### 1. Upgrade to Safe Versions:
* **8.17.6**
* **8.18.1**
* **9.0.1** or newer
### 2. Temporary Workarounds (if you cannot upgrade):
* Disable Machine Learning:
```http
xpack.ml.enabled: false
xpack.ml.ad.enabled: false
```
* Or disable Reporting:
```json
xpack.reporting.enabled: false
```
---
### 3. Usage:
```http
sudo python3 CVE-2025-25014.py -u username -p password --proxy proxy_url url
```
---
## ⚠️ Risk Analysis
* Disclosed in **May 2025**
* Can lead to **full system compromise** if exploited
* The vulnerability abuses JavaScript object structure to inject code through polluted prototypes
* Not currently known to be exploited at scale, but PoCs exist

## 🧭 What You Should Do
1. **Scan** your Kibana servers and check if they’re running a vulnerable version.
2. **Upgrade immediately** to one of the fixed versions if ML or Reporting is used.
3. If you can’t upgrade, **disable the affected features** to reduce exposure.
4. **Monitor logs** for suspicious API activity targeting ML or Reporting endpoints.
5. If exposed to the internet, consider adding **firewall rules or access controls** around Kibana.
