Unauthenticated code execution via service format string
Published Oct 6, 2026 · Updated Oct 6, 2026
Format string flaw in HPE Aruba Networking ClearPass Policy Manager 6.11.0 through 6.11.15 and 6.14.0 allows remote attackers to execute code. An affected service interface processes attacker-controlled input as a format string and corrupts process memory; the specific interface and call site have not been disclosed. Exploitation requires network access to that service but no authentication, and successful memory corruption permits arbitrary code execution.
