Technical details
The AuthAgent and AuthExternal routers in ns-admin contain hardcoded HTTP Basic Auth credentials (nextagent:nextagent and nEXtSCAnExTERNal:nEXtSCAnExTERNal). An unauthenticated network attacker can use these credentials to call the /agent/config endpoint and other protected APIs, exposing Redis passwords, etcd cluster details, and server tokens, then impersonate scan nodes via registration, heartbeat, and logging endpoints.
