CVE-2025-70236
Published: 03 March 2026
Summary
CVE-2025-70236 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 43.5th 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-2025-70236 is a stack buffer overflow vulnerability affecting the D-Link DIR-513 router in version 1.10. The flaw occurs via the curTime parameter in the goform/formSetDomainFilter endpoint, corresponding to CWE-787 (Out-of-bounds Write) and CWE-121 (Stack-based Buffer Overflow). It has been assigned 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 critical severity due to its potential for severe impact.
A remote, unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation could lead to high confidentiality, integrity, and availability impacts, potentially enabling arbitrary code execution, data compromise, or denial of service on the affected device.

Directly prevents stack buffer overflow by validating the length and type of the curTime parameter in the goform/formSetDomainFilter endpoint.
Requires timely remediation of the identified buffer overflow flaw through firmware patching as advised by D-Link security bulletins.
Implements memory protections like stack canaries and DEP to prevent arbitrary code execution from successful stack buffer overflows.
