Description

This security bulletin contains information about 1 security vulnerability.


1) Inadequate Encryption Strength (CVE-ID: CVE-2019-15126)

The 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.
