CVE-2025-45847Public exploitNetwork attack vector

Memory corruption via unchecked targetAPMac copy

Published May 8, 2025 · Updated May 12, 2025

Stack-based buffer overflow in ALFA AIP-W512 3.2.2.2.3 allows remote authenticated users to corrupt memory via targetAPMac. formWsc copies targetAPMac into local_40 until the input ends without enforcing the 24-byte bound, overwriting adjacent stack data. An authenticated POST to the router's management endpoint is required; the public proof of concept establishes an overflow, not code execution or a crash.
