Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, Cisco SD-WAN Viptela Software is affected by a privilege escalation vulnerability. A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands to be executed with Administrator 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 the device and submitting crafted input to the CLI. The attacker must be authenticated as a low-privileged user to execute the affected commands. A successful exploit could allow the attacker to execute commands with Administrator privileges.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
