Summary

CVE-2025-70244 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Dlink Dir-513 Firmware. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 46th 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 map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-70244 is a stack buffer overflow vulnerability (CWE-121) affecting the D-Link DIR-513 router in version 1.10. The flaw resides in the handling of the webPage parameter sent to the goform/formWlanSetup endpoint, which can be triggered over the network via the device's web interface.

A remote unauthenticated attacker can exploit this vulnerability with low complexity and no user interaction required, as indicated by its CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Successful exploitation leads to a denial-of-service condition through high-impact availability disruption, such as device crashes or reboots, without affecting confidentiality or integrity.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and analysis can discover stack-buffer overflows before deployment.

Input validation directly stops untrusted data from exceeding stack buffer bounds.

Memory-protection mechanisms limit the ability to execute injected code after a stack overflow.

Secure-engineering principles include bounds-checked coding and safe buffer handling that avoid introducing the flaw.
