Improper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in AE1021 firmware versions 2.0.10 and earlier and AE1021PE firmware versions 2.0.10 and earlier, which may allow a logged-in user to execute an arbitrary OS command using a crafted HTTP request.
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 when it is sent to a downstream component.
