Official description

Authenticated command injection vulnerabilities exist in the AOS-CX Network Analytics Engine via NAE scripts. Successful exploitation of these vulnerabilities result in the ability to execute arbitrary commands as a privileged user on the underlying operating system, leading to a complete compromise of the switch running AOS-CX in ArubaOS-CX Switches version(s): AOS-CX 10.10.xxxx: 10.10.0002 and below, AOS-CX 10.09.xxxx: 10.09.1030 and below, AOS-CX 10.08.xxxx: 10.08.1070 and below, AOS-CX 10.06.xxxx: 10.06.0210 and below. Aruba has released upgrades for ArubaOS-CX Switch Devices that address these security vulnerabilities.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
