CWE-770

Description

An unauthenticated remote client can cause excessive CPU consumption on a MongoDB server by sending a specific combination of parameters to the awaitable hello command in exhaust mode. The server's handling of this combination results in a response loop that bypasses normal throttling, allowing a small number of connections to degrade server availability.

Affected configurations

• mongodb mongodb (>= 7.0.0 < 7.0.39) • mongodb mongodb (>= 8.0.0 < 8.0.28) • mongodb mongodb (>= 8.2.0 < 8.2.12) • mongodb mongodb (>= 8.3.0 < 8.3.7)
