CVE-2024-3374Network attack vector

Unauthenticated server crash via oversized FTDC BSON

Published May 14, 2024 · Updated Aug 1, 2024

Reachable assertion in MongoDB Server 5.0 through 5.0.16 and 6.0 through 6.0.5 allows remote attackers to crash mongod. While FTDC generates diagnostic metrics, mongod attempts to build a BSON object beyond the permitted memory size and terminates on a fatal assertion. Network access without authentication is sufficient; the reported consequence is interruption of the database service, not data disclosure or modification.
