GTK Re-encryption Flaw in Wi-Fi AP Enables MitM Attacks

Publication date: 2026-03-04

Last updated on: 2026-03-09

Assigner: Hewlett Packard Enterprise (HPE)

Description
A vulnerability in the packet processing logic may allow an authenticated attacker to craft and transmit a malicious Wi-Fi frame that causes an Access Point (AP) to classify the frame as group-addressed traffic and re-encrypt it using the Group Temporal Key (GTK) associated with the victim's BSSID. Successful exploitation may enable GTK-independent traffic injection and, when combined with a port-stealing technique, allows an attacker to redirect intercepted traffic to facilitate machine-in-the-middle (MitM) attacks across BSSID boundaries.

Executive Summary

This vulnerability exists in the packet processing logic of certain access points. An authenticated attacker can craft and send a malicious Wi-Fi frame that tricks the access point into treating the frame as group-addressed traffic. The access point then re-encrypts this frame using the Group Temporal Key (GTK) associated with the victim's BSSID.

Exploiting this flaw allows the attacker to inject traffic that does not depend on the GTK. When combined with a port-stealing technique, the attacker can redirect intercepted traffic, enabling machine-in-the-middle (MitM) attacks across different BSSID boundaries.

Impact Analysis

The vulnerability can allow an attacker to inject unauthorized traffic into the network and redirect intercepted traffic between different BSSIDs. This can lead to machine-in-the-middle attacks, where the attacker can intercept, modify, or redirect network communications.

Such attacks can compromise the confidentiality of communications and potentially allow unauthorized access to sensitive information or network resources.
