Summary

A vulnerability in the Cisco SD-WAN Solution could allow an authenticated, remote attacker to overwrite arbitrary files on the underlying operating system of an affected device. The vulnerability is due to improper input validation of the request admin-tech command in the CLI of the affected software. An attacker could exploit this vulnerability by modifying the request admin-tech command in the CLI of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the underlying operating system of an affected device and escalate their privileges to the root user. This vulnerability affects the following Cisco products if they are running a release of the Cisco SD-WAN Solution prior to Release 18.3.0: vBond Orchestrator Software, vEdge 100 Series Routers, vEdge 1000 Series Routers, vEdge 2000 Series Routers, vEdge 5000 Series Routers, vEdge Cloud Router Platform, vManage Network Management Software, vSmart Controller Software. Cisco Bug IDs: CSCvi69852, CSCvi69856.
