Alert meAnalysisAIv1 – Mar 12, 2026
Traffic interception in ArubaOS Wi-Fi networks allows adjacent attackers to bypass BSSID isolation controls and redirect victim traffic by exploiting port associations across multiple wireless networks. Successful attacks could enable eavesdropping, session hijacking, or denial of service without authentication or user interaction. No patch is currently available for this medium-severity vulnerability.
Earlier versions of this analysis (1)
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. [CVSS 5.4 MEDIUM]
