CVE-2025-70229
Published: 05 March 2026
Description
Stack buffer overflow vulnerability in D-Link DIR-513 v1.10 via the curTime parameter to goform/formSchedule.
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the CVE by requiring timely remediation of the stack buffer overflow flaw through firmware patching as advised in vendor bulletins.
Prevents exploitation of the vulnerability by validating the curTime parameter input to the goform/formSchedule endpoint against expected formats and lengths.
Protects against stack buffer overflow execution by implementing memory safeguards such as stack canaries and non-executable memory regions in the router firmware.
Security SummaryAI
CVE-2025-70229 is a stack buffer overflow vulnerability (CWE-121) in D-Link DIR-513 router version 1.10. The flaw occurs via the curTime parameter sent to the goform/formSchedule endpoint, which can lead to overflow conditions when processing malformed input.
The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating it is exploitable remotely over the network by unauthenticated attackers with low complexity and no requirement for user interaction. Exploitation can achieve high impacts on confidentiality, integrity, and availability, potentially allowing arbitrary code execution, system compromise, or denial of service on affected devices.
Advisories and mitigation guidance are available through vendor resources, including the D-Link security bulletin at https://www.dlink.com/en/security-bulletin/, product support page at https://www.dlink.com.cn/techsupport/ProductInfo.aspx?m=DIR-513, and a detailed CVE report on GitHub at https://github.com/akuma-QAQ/CVEreport/tree/main/D-link/CVE-2025-70229. Security practitioners should review these for patch availability and recommended actions.
