Unauthenticated service interruption via unchecked sprintf copy
Published Oct 24, 2025 · Updated Oct 24, 2025
Stack-based buffer overflow in D-Link DIR-600L Ax firmware 1.16WWb01 allows remote attackers to interrupt service via curTime. The formLogDnsquery handler copies the attacker-controlled curTime value into v30 with sprintf without checking its length, overrunning the stack buffer. Network access without authentication or user interaction is sufficient, and published evidence limits the consequence to service interruption rather than data disclosure or modification.
