This significantly impacts Confidentiality, as sensitive data can be intercepted. Integrity is compromised because attackers can alter intercepted data. Availability is also affected, as the attack exploits the auto-disconnect feature in certain VPN clients, causing the VPN to disable when the device connects to a predefined \u201ctrusted\u201d WiFi network, leaving the user unprotected. The impact is Moderate, because of the attack limitations: credentials of the valid WiFi network and malicious one suppose to be the same.", "threat_severity": "Moderate"}
