Cisco released fixes to address multiple vulnerabilities in its SD-WAN Solution software, where an attacker could leverage them to take control of a system.

Cisco fixed three issues rated high and two rated medium.

There is one vulnerability in Cisco SD-WAN Solution software could allow an authenticated, local attacker to elevate privileges to root on the underlying operating system. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted request to an affected system. A successful exploit could allow the attacker to gain root-level privileges.

While Cisco did release updates, there are no workarounds, officials said in the advisory.

This vulnerability affects the following products if they are running a Cisco SD-WAN Solution software release earlier than Release 19.2.2:

  • vBond Orchestrator Software
  • vEdge 100 Series Routers
  • vEdge 1000 Series Routers
  • vEdge 2000 Series Routers
  • vEdge 5000 Series Routers
  • vEdge Cloud Router Platform
  • vManage Network Management System
  • vSmart Controller Software

In addition, there is a high-rated vulnerability in the CLI of Cisco SD-WAN Solution 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.

Cisco released updates, however, there are no workarounds that address this vulnerability, according to its advisory.

  • vManage Network Management System
  • vSmart Controller Software

In addition, there is a vulnerability in Cisco SD-WAN Solution software could allow an authenticated, local attacker to cause a buffer overflow on an affected device.

The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to gain access to information they are not authorized to access and make changes to the system that they are not authorized to make.

Cisco released updates, however, there are no workarounds that address this vulnerability, according to its advisory.
