CVE-2024-9914Network attack vector

Authenticated router crash via unchecked curTime length

Published Oct 13, 2024 · Updated Oct 15, 2024

Buffer overflow in D-Link DIR-619L B1 2.06 allows remote authenticated users to crash the router through a crafted curTime parameter. The formSetWizardSelectMode handler accepts an overlong curTime value without enforcing the receiving buffer's length, causing writes beyond that buffer. Access to the web-management interface is required, and public evidence establishes a service-interrupting crash but does not establish arbitrary code execution.
