Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents the stack buffer overflow by enforcing validation of the curTime parameter for proper length, type, and format prior to processing.
Mandates timely flaw remediation through vendor patches addressing the buffer overflow in the goform/formSetWizardSelectMode endpoint.
Implements memory protections like stack canaries, non-executable stacks, and ASLR to block exploitation of the stack buffer overflow vulnerability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct unauthenticated remote stack buffer overflow in public-facing web endpoint enabling arbitrary code execution on network device.
NVD Description
Stack buffer overflow vulnerability in D-Link DIR-513 v1.10 via the curTime parameter to goform/formSetWizardSelectMode.
Deeper analysisAI
CVE-2025-70245 is a stack buffer overflow vulnerability (CWE-787, CWE-121) in D-Link DIR-513 router version 1.10. The flaw occurs via the curTime parameter sent to the goform/formSetWizardSelectMode endpoint, which can be triggered over the network. Published on 2026-03-12, 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.
Unauthenticated remote attackers can exploit this vulnerability without privileges or user interaction, requiring only low attack complexity. Exploitation enables high-impact compromise of confidentiality, integrity, and availability, likely resulting in arbitrary code execution and full router control.
