According to its self-reported version, Cisco SD-WAN vManage is affected by a command injection vulnerability in its remote management feature due to insufficient validation of commands to the remote management CLI. An authenticated, local attacker can exploit this, by sending specially crafted requests to an affected host, to execute arbitrary commands and potentially gain elevated privileges.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
