EUVDB-ID: #VU25646
Risk: Low
CVSSv3.1: 6.2 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P/RL:U/RC:C]
CVE-ID: CVE-2019-15126
CWE-ID:
CWE-326 - Inadequate Encryption Strength
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to decrypt Wi-Fi frames.
The vulnerability exists because after an affected device handles a disassociation event it can send a limited number of Wi-Fi frames encrypted with a static, weak Pairwise Temporal Key (PTK). A remote attacker on the local network can acquire these frames and decrypt them with the static PTK without the knowledge of the security session establishment used to secure the Wi-Fi network.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
