Weaknesses
CWE-502

Description

Deserialization of Untrusted Data (CWE-502) in the Elasticsearch machine learning component can lead to remote code execution via Object Injection (CAPEC-586). A specially crafted trained model artifact could cause attacker-controlled logic to execute with a materially broader system-call surface than intended. Exploitation requires an authenticated user with sufficient privileges to create and deploy trained models.

Affected configurations

• elastic elasticsearch (>= 8.0.0 < 8.19.20) • elastic elasticsearch (>= 9.0.0 < 9.4.5) • elastic elasticsearch 9.5.0
