Official description

An authenticated remote command injection vulnerability exists in the ArubaOS web-based management interface. Successful exploitation of this vulnerability results in the ability to execute arbitrary commands as a privileged user on the underlying operating system. This allows an attacker to fully compromise the underlying operating system on the device running ArubaOS.

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

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.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
