Unauthenticated privileged code execution via CLI format string
Published Sep 1, 2026 · Updated Sep 3, 2026
Format string injection in the AOS-CX command-line interface allows remote attackers to execute privileged code over an adjacent network. HPE has not disclosed the affected command or the specific formatting operation that treats attacker-controlled CLI input as a format string. No authentication or user interaction is required, and successful exploitation grants privileged execution on the switch operating system across the listed affected release branches.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
