Summary

CVE-2025-70245 is a critical-severity Out-of-bounds Write (CWE-787) 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 43.8th 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).

Deeper analysis

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.

Mitigation guidance and patches are detailed in vendor advisories, 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 CVE report at https://github.com/akuma-QAQ/CVEreport/tree/main/D-link/CVE-2025-70245.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly prevents the stack buffer overflow by enforcing validation of the curTime parameter for proper length, type, and format prior to processing.

prevent

Mandates timely flaw remediation through vendor patches addressing the buffer overflow in the goform/formSetWizardSelectMode endpoint.

prevent

Implements memory protections like stack canaries, non-executable stacks, and ASLR to block exploitation of the stack buffer overflow vulnerability.
