Cisco Confirms Active Exploitation of SD‑WAN Manager Flaws
🔔Cisco has confirmed active exploitation of two vulnerabilities in Catalyst SD‑WAN Manager (formerly SD‑WAN vManage). CVE-2026-20122 (CVSS 7.1) permits an authenticated remote attacker with valid read‑only API credentials to overwrite arbitrary files on the local filesystem, while CVE-2026-20128 (CVSS 5.5) could allow an authenticated user to obtain Data Collection Agent (DCA) privileges. Cisco has released fixes across affected 20.x releases and urges immediate upgrades and mitigations such as restricting access, disabling HTTP, securing appliances behind firewalls, changing default passwords, and monitoring logs for unexpected activity.
