CVE-2024-26305Network attack vector

Unauthenticated privileged code execution via PAPI overflow

Published May 1, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in the Utility daemon in HPE ArubaOS and EdgeConnect SD-WAN allows remote attackers to execute privileged code. The daemon mishandles specially crafted packets sent to the PAPI management protocol on UDP port 8211, overflowing a stack buffer. No authentication or user interaction is required, and successful exploitation grants arbitrary code execution as a privileged operating-system user.
