CVE-2025-13547 Details
Description
A flaw has been found in D-Link DIR-822K and DWR-M920 1.00_20250513164613/1.1.50. This affects an unknown part of the file /boafrm/formDdns. This manipulation of the argument submit-url causes memory corruption. The attack may be initiated remotely. The exploit has been published and may be used.
A critical buffer overflow vulnerability has been identified in the D-Link DIR-822K and DWR-M920 routers, specifically in the firmware versions 1.00_20250513164613 and 1.1.50. The vulnerability resides in the '/boafrm/formDdns' endpoint, within a function that processes the 'submit-url' parameter using 'strcpy' without proper input validation. This oversight allows remote attackers to send oversized 'submit-url' values, leading to stack memory overwriting, application crashes, memory corruption, and potentially arbitrary code execution on the device.
