Technical description

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to bypass authorization, enabling them to access sensitive information, modify the system configuration, or impact the availability of the affected system. The vulnerability is due to insufficient authorization checking on the affected system. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface of an affected system. A successful exploit could allow the attacker to gain privileges beyond what would normally be authorized for their configured user authorization level. The attacker may be able to access sensitive information, modify the system configuration, or impact the availability of the affected system.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
