Upon successful execution of the exploit, a backdoor is inserted into the firmware, allowing remote read/write commands to be issued to the firmware via crafted action frames (thus allowing easy remote control over the Wi-Fi chip).Beniamini added.

An attacker can run the code remotely which results in the installation of simple backdoor allowing read/write access to the firmware.

By installing the backdoor attacker can gain R/W access to the firmware and no user interaction is needed. Beniamini released PoC script and also the steps to run the exploit.
