Official description
An authenticated remote code execution vulnerability exists in the AOS-CX Network Analytics Engine. Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system, leading to a complete compromise of the switch running AOS-CX.

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.
