Multiple TP-LINK products allow a network-adjacent attacker with an administrative privilege to execute arbitrary OS commands by restoring a crafted backup file. The affected device, with the initial configuration, allows login only from the LAN port or Wi-Fi.
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.
