CVE-2025-70229 is a critical-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Dlink Dir-513 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 32.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
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.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The vulnerability is a remotely exploitable stack buffer overflow in a public-facing web endpoint on a D-Link router, directly enabling exploitation of a public-facing application for arbitrary code execution.
NVD Description
Stack buffer overflow vulnerability in D-Link DIR-513 v1.10 via the curTime parameter to goform/formSchedule.
Deeper analysisAI
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.
