CVE-2018-0274

Status: ModifiedHigh (8.8)—

A vulnerability in the CLI parser of Cisco Network Services Orchestrator (NSO) could allow an authenticated, remote attacker to execute arbitrary shell commands with the privileges of the root user. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by injecting malicious arguments into vulnerable commands. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the affected system. This vulnerability affects the following releases of Cisco Network Services Orchestrator (NSO): 4.1 through 4.1.6.0, 4.2 through 4.2.4.0, 4.3 through 4.3.3.0, 4.4 through 4.4.2.0. Cisco Bug IDs: CSCvf99982.

CVSS
