A vulnerability exists in the wireless encryption handling of Wi-Fi transmissions within HPE Aruba Networking AOS. The flaw allows a malicious actor within radio range to generate shared-key authenticated transmissions. These transmissions contain targeted payloads while successfully impersonating the identity of a primary Basic Service Set Identifier (BSSID). Successful exploitation enables the delivery of tampered data to specific endpoints, effectively bypassing standard cryptographic separation mechanisms. This compromises the integrity of the data stream between the Access Point and the client. The root cause lies in improper validation of the origin of encrypted frames. An attacker does not require any prior authentication to the network to launch this attack. The CVSS vector indicates the attack is adjacent (network range), low complexity, and requires no privileges or user interaction. The impact is limited to low integrity and low confidentiality impacts with no availability impact . The vulnerability affects multiple versions of ArubaOS . HPE has released patches to address this issue .
DailyCVE Form
Platform: HPE Aruba Networking AOS
Version: 10.4.x <10.4.1.11, 10.7.x <10.7.2.3, 8.10.x <8.10.0.22
Vulnerability: Wireless encryption bypass
Severity: Medium (CVSS 5.4)
Date: March 4, 2026
Prediction: Patches released Mar 3, 2026
What Undercode Say:
Analytics:
The vulnerability exploits a failure in 802.11 encryption context verification. Attackers can inject forged packets encrypted with a valid shared key. The attack targets the data plane, bypassing higher-level security policies.
Exploit:
An attacker uses a modified Wi-Fi adapter. They capture beacons from a legitimate AP. The exploit script crafts a malicious EAPoL or data frame. It uses the BSSID of the target AP. The frame is encrypted with the known Group Temporal Key (GTK) or a derived key. The script injects this frame to a specific client, causing it to accept tampered data. This often involves using `aireplay-ng` with custom patches or tools like `mdk4` in custom injection modes.
Example: Theoretical injection using a modified tool sudo modprobe mac80211_hwsim radios=2 sudo airmon-ng start wlan0 sudo ./craft_injection --bssid TARGET_AP_MAC --client VICTIM_MAC --interface wlan0mon --payload "malicious_data.bin"

Impact:
Exploitation allows attackers to inject arbitrary data into a client’s session. This leads to data integrity violation. It can be used to redirect traffic, conduct machine-in-the-middle attacks, or deliver malicious payloads within a trusted network segment. Confidentiality is also partially compromised as traffic may be redirected to the attacker.
