CVE-2026-23822: Vulnerability in Hewlett Packard Enterprise (HPE) ArubaOS (AOS)
A vulnerability in the XML handling component of AOS-8 DHCP services could allow an unauthenticated remote attacker to trigger a denial-of-service condition. Successful exploitation could allow an attacker to cause excessive resource consumption upon user interaction, leading to service disruption or reduced availability of the affected system. NOTE: This vulnerability only impacts Access Points running AOS Instant 8.x.x.x
AI Analysis
Technical Summary
This vulnerability exists in the XML handling component of the DHCP services on ArubaOS Instant 8.x Access Points. An unauthenticated remote attacker can exploit this flaw to trigger excessive resource consumption, causing a denial-of-service (DoS) condition. The affected versions include 8.10.0.0, 8.12.0.0, and 8.13.0.0. The CVSS 3.1 base score is 5.3, reflecting medium severity with network attack vector, high attack complexity, no privileges required, user interaction required, and impact limited to availability. No patch or official remediation level has been disclosed by HPE as of the published date.
Potential Impact
Successful exploitation results in denial-of-service by causing excessive resource consumption on affected ArubaOS Instant Access Points, leading to service disruption or reduced system availability. There is no impact on confidentiality or integrity reported. The vulnerability requires user interaction and has a high attack complexity, limiting the ease of exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary mitigation has been disclosed, users should monitor HPE advisories for updates. Until a patch is available, limiting exposure of affected devices to untrusted networks and minimizing user interaction with potentially malicious DHCP responses may reduce risk.
