CVE-2024-42393Network attack vector

Unauthenticated RCE via PAPI stack buffer overflow

Published Aug 6, 2024 · Updated Aug 12, 2024

Stack-based buffer overflow in HPE Aruba Instant 8.10.0.0 through 8.10.0.12 and 8.12.0.0 through 8.12.0.1 allows remote attackers to execute commands. The Soft AP Daemon Service writes PAPI-protocol input past a stack buffer boundary, corrupting memory used to control command execution. No authentication or user interaction is required; network access to the PAPI service enables complete control of the access point.
