Description

NextScan 1.1.0 through 1.2.0 contains hardcoded HTTP Basic Auth credentials in ns-admin's AuthAgent and AuthExternal routers that allow unauthenticated attackers to access protected APIs. Attackers can call /agent/config to obtain Redis passwords, etcd details and the server token, and impersonate scan nodes via registration, heartbeat and logging endpoints.
