CVE-2026-23601 identifies a vulnerability in the wireless encryption handling mechanism of Hewlett Packard Enterprise's Aruba Networking Wireless Operating System versions AOS-10 and AOS-8. The issue allows a malicious actor to craft shared-key authenticated Wi-Fi transmissions that impersonate the primary Basic Service Set Identifier (BSSID). By doing so, the attacker can inject targeted payloads into the wireless communication stream, effectively delivering tampered data to specific endpoints. This bypasses the standard cryptographic separation mechanisms designed to protect data confidentiality and integrity within the wireless network. The vulnerability is classified under CWE-327, indicating weaknesses in cryptographic algorithms or their implementation. The CVSS v3.1 base score is 5.4 (medium), with an attack vector of adjacent network (AV:A), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts on confidentiality and integrity but not availability. Affected versions include multiple releases of AOS-10 (10.4.0.0, 10.7.0.0, 10.8.0.0) and AOS-8 (8.10.0.0, 8.12.0.0, 8.13.0.0). No patches or exploits are currently publicly available, but the vulnerability poses a risk to the security of wireless communications in environments using these systems.

The vulnerability allows attackers to impersonate the primary BSSID and inject malicious payloads into authenticated Wi-Fi transmissions, compromising the confidentiality and integrity of wireless data. This can lead to unauthorized data manipulation, interception, or injection of malicious commands within the wireless network. Organizations relying on HPE Aruba wireless infrastructure for critical communications may face risks including data breaches, disruption of wireless services, and potential lateral movement within internal networks. Since the attack requires only adjacent network access and no authentication, attackers physically near or connected to the wireless network can exploit this flaw. This elevates risks in environments such as corporate campuses, government facilities, healthcare institutions, and industrial control systems where secure wireless communication is essential. Although availability is not directly impacted, the breach of confidentiality and integrity can have cascading effects on operational security and trust in wireless communications.

1. Monitor Hewlett Packard Enterprise communications for official patches addressing CVE-2026-23601 and apply them promptly across all affected Aruba AOS-10 and AOS-8 devices. 2. Implement strict wireless network segmentation to isolate critical systems and sensitive data from general wireless access, reducing the attack surface. 3. Employ enhanced wireless intrusion detection and prevention systems (WIDS/WIPS) capable of detecting anomalous BSSID impersonation and unauthorized frame injection. 4. Use strong network access controls, including 802.1X authentication and dynamic VLAN assignment, to limit unauthorized device connectivity. 5. Regularly audit wireless network configurations and logs for signs of suspicious activity related to BSSID spoofing or unusual traffic patterns. 6. Educate network administrators on this vulnerability to recognize potential exploitation indicators and respond swiftly. 7. Where feasible, consider deploying additional encryption layers such as VPNs over wireless connections to protect data confidentiality and integrity beyond the wireless link layer. 8. Restrict physical access to wireless infrastructure and limit wireless signal propagation outside controlled areas to reduce adjacent attacker opportunities.
