CVE-2023-38699Network attack vector

Credential interception via disabled Dremio TLS verification

Published Aug 4, 2023 · Updated Oct 3, 2024

Improper TLS certificate validation in MindsDB before 23.7.4.0 allows remote attackers to intercept Dremio login credentials. The Dremio handler's connect method passes verify=False to requests.post when sending the configured username and password to /apiv2/login, accepting an untrusted TLS certificate. A network-path position and a configured Dremio integration are required; successful interception exposes the Dremio username and password.
