Summary

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. ClickHouse's PostgreSQL integration intentionally allows users with valid PostgreSQL credentials to execute queries against a remote PostgreSQL server. No vulnerability in ClickHouse is exploited; code execution occurs on the downstream PostgreSQL server using credentials explicitly provided by the user with specific pg_execute_server_program permission, exploiting a feature that was wrongly reported as CVE-2019-9193 in PostgreSQL (https://www.postgresql.org/about/news/cve-2019-9193-not-a-security-vulnerability-1935/).

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.
