High [CVE-2026-20127 +2] Cisco Catalyst SD-WAN Controller, Catalyst SD-WAN Manager, and Catalyst SD-WAN Validator Authenticated Privilege Escalation Vulnerability
A vulnerability in the CLI of Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, and Cisco Catalyst SD-WAN Validator, formerly SD-WAN vBond, could allow an authenticated, local attacker to execute arbitrary commands as root by supplying a crafted file to the affected system. This vulnerability is due to insufficient validation of user-supplied input. A successful exploit could allow the attacker to perform command injection attacks on an affected system and elevate their privileges as the root user. To exploit this vulnerability, the attacker must have netadmin privileges on the affected system. This would require valid credentials or exploitation of CVE-2026-20182 or CVE-2026-20127. Cisco is not aware of successful exploitation by other methods. Cisco has observed limited cases where the exploitation of this bug resulted in a configuration change pushed to edge devices. Cisco recommends that customers upgrade to the fixed software that is documented in the Catalyst SD-WAN Security Advisory that was published on May 14, 2026, and verify the configuration of the edge devices. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
