Vulnerability Title
MAC Address Spoofing leads to Inter-BSSID Isolation Bypass Resulting in Traffic Redirection
Source: CVE Program / CVE List V5
Vulnerability Description
A technique has been identified that adapts a known port-stealing method to Wi-Fi environments that use multiple BSSIDs. By leveraging the relationship between BSSIDs and their associated virtual ports, an attacker could potentially bypass inter-BSSID isolation controls. Successful exploitation may enable an attacker to redirect and intercept the victim's network traffic, potentially resulting in eavesdropping, session hijacking, or denial of service.
