Official description

Authenticated append-style command-injection Ruijie APs (AP_RGOS 11.1.x) allows an authenticated web user to execute appended shell expressions as root, enabling file disclosure, device disruption, and potential network pivoting via the command parameter to the web_action.do endpoint.

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.
