Summary
CVE-2025-70226 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 stack buffer overflow by enforcing validation of the curTime parameter in the goform/formEasySetupWizard endpoint.
Provides memory protections such as stack canaries and address space layout randomization to prevent exploitation of the stack buffer overflow vulnerability.
Requires timely remediation through firmware patching to eliminate the specific stack buffer overflow flaw in D-Link DIR-513 v1.10.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Stack buffer overflow in unauthenticated web endpoint (goform/formEasySetupWizard) of public-facing router enables remote arbitrary code execution, directly facilitating T1190: Exploit Public-Facing Application.
NVD Description
Stack buffer overflow vulnerability in D-Link DIR-513 v1.10 via the curTime parameter to goform/formEasySetupWizard.
Deeper analysisAI
CVE-2025-70226 is a stack buffer overflow vulnerability (CWE-121) in the D-Link DIR-513 router version 1.10. The flaw occurs in the handling of the curTime parameter sent to the goform/formEasySetupWizard endpoint. Published on 2026-03-04, it 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), marking it as critical due to its potential for severe impact.
An unauthenticated attacker with network access can exploit this vulnerability remotely with low attack complexity and no user interaction required. Exploitation could result in high confidentiality, integrity, and availability impacts, such as arbitrary code execution on the affected device.
