A vulnerability in the CLI of Cisco Network Services Orchestrator (NSO) could allow an authenticated, local attacker to access confidential information on an affected device. The vulnerability is due to a timing issue in the processing of CLI commands. An attacker could exploit this vulnerability by executing a specific sequence of commands on the CLI. A successful exploit could allow the attacker to read configuration information that would normally be accessible to administrators only. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
