CVE-2024-42394Network attack vector

Unauthenticated command execution via PAPI stack overflow

Published Aug 6, 2024 · Updated Aug 7, 2024

Stack-based buffer overflow in the Soft AP Daemon Service in HPE Aruba InstantOS and ArubaOS allows remote attackers to execute commands. The daemon mishandles crafted PAPI messages and writes beyond a stack buffer, allowing control of execution on the access point. No authentication or user interaction is required; network access to PAPI on UDP port 8211 is sufficient for complete system compromise.
