The published paper can be found at https://papers.mathyvanhoef.com/usenix2023-wifi.pdf Affected Products ArubaOS Wi-Fi Controllers and Campus/ Remote Access Points Aruba InstantOS / Aruba Access Points running ArubaOS 10 Aruba Instant On Access Points See Details section for Affected Versions Unaffected Products AirWave Management Platform Aruba Analytics and Location Engine Aruba Central / Central On-Premises ArubaOS SD-Branch and WLAN Gateways - All Versions Aruba Instant On Switches Aruba Wireless Bridge 501 Aruba ClearPass Policy Manager Aruba IntroSpect Aruba Fabric Composer (AFC) and Plexxi Composable Fabric Manager (CFM) Aruba NetEdit Aruba User Experience Insight (UXI) ArubaOS-CX Switches ArubaOS-S Switches HP ProCurve Switches Aruba VIA Client Aruba EdgeConnect Enterprise Orchestrator (on-premises) Aruba EdgeConnect Enterprise Orchestrator-as-a-Service Aruba EdgeConnect Enterprise Orchestrator-SP Aruba EdgeConnect Enterprise (ECOS) Other Aruba products not listed above are also not known to be affected by these vulnerabilities. Details The paper specifically mentions certain Aruba WLAN products running ArubaOS version 8.4.0.0 as affected. After further investigation, Aruba separates the vulnerabilities described in the paper in the following 3 scenarios: 1) Exploiting Power Save Features: No Aruba Products are vulnerable to this scenario. 2) Security Context Override (SCO): All versions of the Aruba products listed under the Affected Products section are vulnerable to this attack. An attacker needs to be authenticated to the Wi-Fi network using valid credentials before being able to carry out the attack. This would imply that the vulnerability requires an insider threat to be exploited. Data encryption such as TLS prevents the disclosure of sensitive information or allowing an attacker to steal the victims session. 3) Fast Reconnect Attack: The following Aruba products and versions are affected: ArubaOS Wi-Fi Controllers and Campus/ Remote Access Points 8.9.0.3 and below 8.6.0.20 and below Aruba InstantOS / Aruba Access Points running ArubaOS 10 10.3.1.0 and below 8.9.0.3 and below 8.8.0.3 and below 8.7.1.11 and below 8.6.0.18 and below 6.5.4.23 and below 6.4.4.8-4.2.4.20 and below Aruba Instant On Access Points. 2.8 and below The published paper can be found at https://papers.mathyvanhoef.com/usenix2023-wifi.pdf Workaround None. Exploitation and Public Discussion These vulnerabilities are being widely discussed in public. The paper specifically mentions certain Aruba WLAN products running ArubaOS version 8.4.0.0 as affected.
