AlienVault OTX Vulnerabilities

AlienVault OTX Malware

aruba-networking-wireless-operating-system

A vulnerability has been identified in a standardized wireless roaming protocol that could enable a malicious actor to install an attacker-controlled Group Temporal Key (GTK) on a client device. Successful exploitation of this vulnerability could allow a remote malicious actor to perform unauthorized frame injection, bypass client isolation, interfere with cross-client traffic, and compromise network segmentation, integrity, and confidentiality.

CVE-2026-23808 is a vulnerability identified in Hewlett Packard Enterprise's Aruba Networking Wireless Operating System (AOS) versions 10.8.0.0, 10.7.0.0, 10.4.0.0, 8.13.0.0, 8.12.0.0, and 8.10.0.0. The flaw resides in the implementation of a standardized wireless roaming protocol, which is responsible for managing secure transitions of client devices between access points within a wireless network. Specifically, the vulnerability allows a remote attacker to install an attacker-controlled Group Temporal Key (GTK) on a client device. The GTK is a key used to encrypt multicast and broadcast traffic within a wireless network segment. By manipulating the GTK, an attacker can perform unauthorized frame injection, which means they can send forged frames that appear legitimate to other clients and network devices. This capability enables bypassing client isolation mechanisms designed to prevent direct client-to-client communication, thereby interfering with cross-client traffic. The compromise of GTK integrity undermines network segmentation, potentially allowing attackers to access or disrupt traffic meant to be isolated. The vulnerability does not require any privileges or user interaction, making it easier to exploit remotely. The CVSS v3.1 base score is 5.4 (medium severity), reflecting the attack vector as adjacent network (wireless), low attack complexity, no privileges required, no user interaction, and limited impact on confidentiality and integrity but no impact on availability. Although no known exploits are currently reported in the wild, the vulnerability represents a significant risk to wireless network security, especially in enterprise environments relying on HPE Aruba wireless infrastructure for secure roaming and segmentation.
