CVE-2025-60548Network attack vector

Unauthenticated memory corruption via unchecked sprintf copy

Published Oct 24, 2025 · Updated Oct 24, 2025

Buffer overflow in D-Link DIR-600L Ax firmware 1.16WWb01 allows remote attackers to corrupt memory through a crafted curTime value. The formLanSetupRouterSettings handler passes the untrusted parameter to sprintf, which copies it into v33 without checking its length. The network path requires no authentication or user action; the published report establishes memory corruption but withholds runnable exploit code.
