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.

Security readout for executives and security teams

This flaw lets a logged-in remote user abuse a Cisco SD-WAN CLI function to overwrite files on the device. If successful, the attacker could become root, turning ordinary administrative access into full operating-system control. Exposure is limited to Cisco SD-WAN deployments running affected software before Release 18.3.0 on vBond, vEdge, vManage, or vSmart components. The attacker must be authenticated and able to access the CLI. Treat this as high priority where legacy Cisco SD-WAN components remain in service. The attacker needs credentials, but successful exploitation can convert access into root control of critical network infrastructure. Mitigation focus: Upgrade affected Cisco SD-WAN components to Release 18.3.0 or later per Cisco guidance.; Prioritize vManage, vSmart, vBond, and internet-reachable or broadly administered vEdge assets.; Restrict SD-WAN CLI access to trusted administrative networks and named administrators..
