CVE-2024-9783Network attack vector

Authenticated memory corruption via oversized curTime parameter

Published Oct 10, 2024 · Updated Oct 10, 2024

Buffer overflow in D-Link DIR-619L B1 2.06 allows remote authenticated users to corrupt memory through a crafted curTime value. The /goform/formLogDnsquery handler copies attacker-controlled curTime data without checking the destination size, overflowing its buffer. Access to the router's authenticated web interface is required; published evidence does not establish whether exploitation causes only a service interruption or enables code execution.
