Details

Wazuh Manager before 5.0.0-beta3 fails to escape the DataValue.index field when constructing OpenSearch bulk requests, allowing enrolled agents to inject arbitrary NDJSON operations. Attackers can smuggle delete, index, or update operations into bulk requests executed under the manager's admin credentials, enabling document deletion, alert tampering, and cross-agent SIEM state manipulation.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
