CVE-2019-1646 Detail

Description

A vulnerability in the local CLI of the Cisco SD-WAN Solution could allow an authenticated, local attacker to escalate privileges and modify device configuration files. The vulnerability exists because user input is not properly sanitized for certain commands at the CLI. An attacker could exploit this vulnerability by sending crafted commands to the CLI of an affected device. A successful exploit could allow the attacker to establish an interactive session with elevated privileges. The attacker could then use the elevated privileges to further compromise the device or obtain additional configuration data from the device.

CVSS 3.x Severity and Metrics:

NIST: NVD

Base Score: 7.8 HIGH

Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Nist CVSS score does not match with CNA score

CNA: Cisco Systems, Inc.

Base Score: 7.8 HIGH

Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
