CVE-2022-20739 Detail

Current Description

A vulnerability in the CLI of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as the root user. The attacker must be authenticated on the affected system as a low-privileged user to exploit this vulnerability. This vulnerability exists because a file leveraged by a root user is executed when a low-privileged user runs specific commands on an affected system. An attacker could exploit this vulnerability by injecting arbitrary commands to a specific file as a lower-privileged user and then waiting until an admin user executes specific commands. The commands would then be executed on the device by the root user. A successful exploit could allow the attacker to escalate their privileges on the affected system from a low-privileged user to the root user.

CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  7.3 HIGH
Vector:  CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H

Nist CVSS score does not match with CNA score
CNA:  Cisco Systems, Inc.
Base Score:  7.3 HIGH
Vector:  CVSS:3.0/AV:L/AC:L/PR:L/UI:R/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.
