Root Cause Analysis
The vulnerability exists in the standalone master's RPC handling where authentication checks were missing. The Master.receive()
method is the main entry point for RPC messages, and methods like handleRegisterApplication would process application submissions. The CVE description explicitly states authentication bypass in application resource startup RPCs, indicating missing auth checks in these message handlers. While exact patch details aren't shown, the Spark security advisory and architecture analysis confirm these are the critical authentication points.
