CVE-2020-3158 Detail

Current Description

A vulnerability in the High Availability (HA) service of Cisco Smart Software Manager On-Prem could allow an unauthenticated, remote attacker to access a sensitive part of the system with a high-privileged account. The vulnerability is due to a system account that has a default and static password and is not under the control of the system administrator. An attacker could exploit this vulnerability by using this default account to connect to the affected system. A successful exploit could allow the attacker to obtain read and write access to system data, including the configuration of an affected device. The attacker would gain access to a sensitive portion of the system, but the attacker would not have full administrative rights to control the device.

CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  9.1 CRITICAL
Vector:  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Nist CVSS score does not match with CNA score
CNA:  Cisco Systems, Inc.
Base Score:  9.8 CRITICAL
Vector:  CVSS:3.0/AV:N/AC:L/PR:N/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.
