CVE-2022-20739

7.3 HIGH 0.6% exploit odds Fix listed

What it is

A vulnerability in the CLI of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as the root user. The attacker must be authenticated on the affected system as a low-privileged user to exploit this vulnerability. This vulnerability exists because a file leveraged by a root user is executed when a low-privileged user runs specific commands on an affected system. An attacker could exploit this vulnerability by injecting arbitrary commands to a specific file as a lower-privileged user and then waiting until an admin user executes specific commands. The commands would then be executed on the device by the root user. A successful exploit could allow the attacker to escalate their privileges on the affected system from a low-privileged user to the root user.

At a glance

Exploitability: Can be exploited locally on the machine with a low-privilege account, but needs a user to act. High risk of data exposure, data tampering, service disruption.
Exploit odds: 0.6% chance of exploitation in the next 30 days (EPSS).
Fix: A patch, advisory or fixed version is referenced. Upgrade or apply it.
