Authenticated service disruption via undisclosed CLI flaw
Published Sep 1, 2026 · Updated Sep 2, 2026
Denial of service in the AOS-CX command-line interface allows remote authenticated users to disrupt normal switch operation. HPE has not disclosed the affected CLI commands, the triggering input, or the internal operation that causes the disruption. Exploitation requires low-privileged network access to the management CLI and high attack complexity; no confidentiality or integrity impact is reported.
