Cisco IOS XE SD-WAN Software Command Injection Vulnerability
Description
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands to be executed with root-level privileges on the underlying operating system. This vulnerability is due to insufficient input validation on certain CLI commands. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the CLI. The attacker must be authenticated as an administrative user to execute the affected commands. A successful exploit could allow the attacker to execute commands with root-level privileges.

Cisco IOS XE SD-WAN Software CLI command injection allows authenticated local admin to execute arbitrary commands with root privileges.
Vulnerability
The vulnerability is a command injection in the CLI of Cisco IOS XE SD-WAN Software, due to insufficient input validation on certain CLI commands. Affected devices include Cisco 1000 Series, 4000 Series, ASR 1000 Series, and Cloud Services Router 1000V Series running vulnerable releases of Cisco IOS XE SD-WAN Software with the SD-WAN feature enabled (not default). The SD-WAN feature must be enabled for exploitation, as described in the advisory [1].
Exploitation
An attacker must be authenticated as an administrative user on an affected device. The attacker then submits crafted input to vulnerable CLI commands. No further user interaction or network access beyond local CLI is required [1].
Impact
Successful exploitation allows the attacker to execute arbitrary commands with root-level privileges on the underlying operating system, resulting in full compromise of the device (confidentiality, integrity, and availability) [1].
Mitigation
Cisco has released fixed software versions for this vulnerability. Customers should upgrade to a fixed release as specified in the advisory [1]. No workarounds are available; the only mitigation is to apply the patch or disable the SD-WAN feature if not required.
