Technical details

An OS command injection vulnerability (CWE-78) exists in the command line interface (CLI) of Aruba Access Points running AOS-10 and AOS-8 Instant. The flaw allows an authenticated remote attacker with high privileges to escape the restricted shell environment. By providing specially crafted input to certain CLI commands, the attacker can execute arbitrary commands with the privileges of the underlying operating system. This can result in a complete compromise of the device's confidentiality, integrity, and availability. The vulnerability is tracked as CVE-2026-23820 and was reported by Hewlett Packard Enterprise.
