CVE-2024-3372Network attack vector

Pre-authentication serverStatus disruption via malformed metadata serialization

Published May 14, 2024 · Updated Aug 1, 2024

Improper input validation in MongoDB Server 5.0, 6.0, and 7.0 allows remote attackers to disrupt serverStatus via crafted metadata. The server accepts certain metadata without sufficient validation and serializes it as invalid BSON; MongoDB has not disclosed the specific field or code path. No authentication or user interaction is required, and the documented consequence is loss of serverStatus responses rather than data access or modification.
