A vulnerability in the command line interface (cli) management interface of Cisco SD-WAN vManage could allow an authenticated, local attacker to bypass authorization and roll back the configuration on vManage controllers and edge router devices. This vulnerability is due to improper access control in the cli-management interface of an affected system. An attacker with low-privilege (read-only) access to the cli could exploit this vulnerability by sending a request to roll back the configuration on other controllers and devices managed by an affected system. A successful exploit could allow the attacker to roll back the configuration on other controllers and devices managed by an affected system.
The severity level of this vulnerability is high, with a CVSS score of 7.1. The implications of such a vulnerability are significant, as it allows unauthorized configuration changes, potentially impacting the functionality and security posture of the affected systems. Organizations leveraging Cisco SD-WAN vManage need to be aware of this vulnerability and take immediate action to address it.
Currently, there are no known exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, given the nature of the vulnerability, it is essential for organizations to prioritize patching the affected systems without delay.
Organizations should prioritize patching immediately. The remediation involves updating to the latest versions of the Cisco SD-WAN vManage and Catalyst SD-WAN Manager components to mitigate the risk associated with this vulnerability.
Vulnerability Details
The vulnerability allows an attacker to bypass authorization controls within the CLI management interface, potentially leading to unauthorized configuration changes.
The vulnerability falls under the CWE-286 classification, which signifies improper access control. The attack vector is local, and the impact on integrity and availability is high.
The affected products include Cisco Catalyst SD-WAN Manager versions 20.7, 20.8, 20.9, 20.11, and Cisco SD-WAN vManage versions prior to 20.6.2, as well as version 20.10.
Technical Analysis
The root cause of this vulnerability is improper access control, which allows a low-privilege user to send unauthorized rollback requests. The attack vector is local, meaning that an attacker must have physical or network access to the affected systems.
The attack complexity is low, and no user interaction is required for the exploit to succeed. The confidentiality impact is none, as the attacker would not gain access to sensitive data, but the integrity and availability impacts are high, as configurations may be altered without authorization.
Risk & Impact Analysis
Risk to organizations includes unauthorized configuration changes that could lead to operational disruptions or security breaches. The potential blast radius is significant, especially for organizations that rely heavily on Cisco SD-WAN for their network operations.
Given the high CVSS score, organizations should address this vulnerability in their priority patch cycle. Timely remediation is crucial to prevent exploitation of this vulnerability.
