CVE-2024-33518Network attack vector

Unauthenticated service interruption via PAPI buffer overflow

Published May 1, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in HPE ArubaOS and EdgeConnect SD-WAN allows remote attackers to interrupt the Radio Frequency Manager service. The Radio Frequency Manager mishandles crafted PAPI protocol input and writes beyond a stack buffer; HPE has not identified the affected routine or field. Unauthenticated network access to PAPI is sufficient, and exploitation affects service availability without reported data disclosure or modification.
