Summary

Hide ▲

CISA added CVE-2026-20262 to its Known Exploited Vulnerabilities (KEV) catalog and required Federal Civilian Executive Branch (FCEB) agencies to apply Cisco's fixes by June 29, 2026, forcing federal remediation of an actively exploited Cisco SD-WAN flaw. The action targets Cisco Catalyst SD-WAN Manager after evidence showed abuse in the wild. Cisco said the flaw could let an authenticated remote attacker create or overwrite files and potentially reach root. The deadline gives federal agencies a clear remediation window for a live exploitation risk.

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.
