PowerPath: Reimpostazione della connessione da parte di un peer quando la vulnerabilità Tenable esegue la scansione della porta 9083

Summary: PowerPath per Windows 7.2.X La gestione remota mTLS (Mutual Transport Layer Security) raggiunge il limite massimo di connessione socket e la connessione viene reimpostata dal peer quando la vulnerabilità Tenable esegue la scansione della porta 9083. ...

Symptoms

Quando il software di scansione Tenable esegue la scansione della porta 9083, il processo di gestione remota di PowerPath con mTLS abilitato non riesce a raggiungere il numero massimo di connessioni socket e viene registrato il ripristino della connessione da parte di un messaggio peer.

 

Nella GUI di PPMA, lo stato disconnesso non viene visualizzato fino al ciclo di polling successivo. Quando viene eseguito il ciclo di polling, il server viene infine visualizzato come disconnesso nella GUI (ROSSO).

Cause

Si tratta di un problema con Gestione remota di PowerPath per Windows 7.2.X con mTLS abilitato che non gestisce correttamente le connessioni Winsock dal server non PPMA.

 

Resolution

La correzione sarà presente nella versione futura di PowerPath per Windows, ma al momento non esiste un ETA.

 

La soluzione alternativa consiste nel riavviare il servizio "Componente EMC PowerPath Remote Management" dai Servizi Windows.
