Analysis Summary
# Vulnerability: Kibana Origin Validation Error Leading to SSRF
## CVE Details
- CVE ID: CVE-2025-37734
- CVSS Score: 4.3 (Medium)
- CWE: Origin Validation Error (Inferred from description)
## Affected Systems
- Products: Kibana (Observability AI Assistant component)
- Versions: 8.12.0–8.19.6, 9.1.0–9.1.6, 9.2.0
- Configurations: Deployments using the Observability AI Assistant feature. Elastic Cloud Serverless users are protected.
## Vulnerability Description
The vulnerability is an **origin validation error** within Kibana’s **Observability AI Assistant component**. Threat actors can exploit this by crafting forged `Origin` HTTP headers. This improper validation bypasses security checks, allowing the attacker to induce the server to make unauthorized Server-Side Requests (SSRF) to internal systems and services.
## Exploitation
- Status: Not explicitly stated as exploited in the wild, but RCE implies high risk. PoC likely exists but not detailed.
- Complexity: Low (Requires low privileges and no user interaction, only network access).
- Attack Vector: Network
## Impact
- Confidentiality: Potential data exfiltration, unauthorized access to internal resources.
- Integrity: Potential unauthorized modification of internal services.
- Availability: Potential denial of service or disruption depending on targeted backend services.
## Remediation
### Patches
Organizations must upgrade to the following fixed versions:
- 8.19.7
- 9.1.7
- 9.2.1
### Workarounds
- Temporarily disable the **Observability AI Assistant** feature until upgrading can be completed.
## Detection
- **Indicators of Compromise:** Monitor access logs for suspicious or forged `Origin` HTTP headers associated with server-side requests originating from Kibana services.
- **Detection methods and tools:** Audit logs for unusual server-side requests targeting internal IP addresses or restricted services originating from the vulnerable component.
