CVE-2023-31997Network attack vector

Unauthenticated MongoDB access via exposed database service

Published Jun 30, 2023 · Updated Nov 26, 2024

Incorrect authorization in Ubiquiti UniFi OS before 3.1.13 allows remote attackers to access MongoDB over a local network. On Cloud Key Gen2 and Cloud Key Gen2 Plus consoles hosting UniFi Network, a configuration exposes MongoDB without enforcing authorization. Exploitation requires local-network reachability to an applicable console and grants direct database access; published details do not specify allowed operations.
