Detailsinfo

A vulnerability, which was classified as critical, was found in Cisco IOS XE SD-WAN (Router Operating System) (affected version not known). This affects some unknown functionality of the component CLI. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands that are executed with root privileges. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by authenticating to the device and submitting crafted input to the CLI utility. The attacker must be authenticated to access the CLI utility. A successful exploit could allow the attacker to execute commands with root privileges.

The weakness was shared 04/29/2020 as cisco-sa-xesdwcinj-AcQ5MxCn as confirmed advisory (Website). The advisory is shared at tools.cisco.com.
