Recentemente è stasta scoperta una vulnerabilità che affligge praticamente tutte le versioni di Cisco IOS (il sistema operativo integrato ai router CISCO), relativa al protocollo NHRP (Next Hop Resolution Protocol). Poichè tale protocollo viene adoperato principalmente nelle WAN clouds oppure nelle LAN emulations (LANE), c’è poco da preoccuparsi per quelli che, come me, possiedono un piccolo router della classe SOHO (Small Office Home Office). A titolo di cronaca, però, è meglio fornire informazioni utili relative al bug in questione, anche per seguire eventuali ulteriori sviluppi.
Qui di seguito sono riportarte le informazioni tecniche riguardanti la vulnerabilità sopra citata:
