Description
A vulnerability has been identified where an attacker connecting to an access point as a standard wired or wireless client can impersonate a gateway by leveraging an address-based spoofing technique. Successful exploitation enables the redirection of data streams, allowing for the interception or modification of traffic intended for the legitimate network gateway via a Machine-in-the-Middle (MitM) position.
