Official description

A vulnerability in the command line interface of Access Points running AOS-10 could allow an authenticated remote attacker to perform command injection. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system. NOTE: This vulnerability only impacts Access Points running AOS-10.7.x.x and above. AOS-10.4 AP and AOS-8 Instant software branches are not affected by this vulnerability.

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.
