CVE-2021-1528: Cisco SD-WAN Software Privilege Escalation Vulnerability
First published: Fri Jun 04 2021(Updated: )
A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to gain elevated privileges on an affected system. This vulnerability exists because the affected software does not properly restrict access to privileged processes. An attacker could exploit this vulnerability by invoking a privileged process in the affected system. A successful exploit could allow the attacker to perform actions with the privileges of the root user.
