Vulnerability Title
Cisco SD-WAN vManage Software Authentication Bypass Vulnerability
Source: CVE Program / CVE List V5
Vulnerability Description
A vulnerability in the web-based messaging service interface of Cisco SD-WAN vManage Software could allow an unauthenticated, adjacent attacker to bypass authentication and authorization and modify the configuration of an affected system. To exploit this vulnerability, the attacker must be able to access an associated Cisco SD-WAN vEdge device. This vulnerability is due to insufficient authorization checks. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based messaging service interface of an affected system.
