Cisco warned that CVE-2026-20245 in Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, is under active exploitation and can let an authenticated local attacker with netadmin privileges upload a crafted file to execute arbitrary commands as root. Cisco said the flaw affects On-Prem Deployment, Cisco SD-WAN Cloud-Pro, Cisco SD-WAN Cloud (Cisco Managed), and Cisco SD-WAN for Government (FedRAMP), that limited exploitation has already resulted in configuration changes pushed to edge devices, and that no patches or mitigations are currently available. Cisco also advised checking /var/log/scripts.log for indicators of compromise and credited Google Mandiant researchers Chester Sng, Pete Boonyakarn, and Logeswaran Nadarajan with discovering and reporting the issue.
