Summary
CVE-2025-70219 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
Validates inputs to the goform/formDeviceReboot endpoint to prevent stack buffer overflows from malformed remote requests.
Implements memory protections like stack canaries and ASLR to block arbitrary code execution even if the buffer overflow occurs.
Requires timely patching of the known stack buffer overflow flaw in D-Link DIR-513 v1.10 firmware.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The vulnerability is a remotely exploitable stack buffer overflow in the public-facing web interface of a router, enabling arbitrary code execution without authentication, directly mapping to exploitation of public-facing applications.
NVD Description
Stack buffer overflow vulnerability in D-Link DIR-513 v1.10 via the goform/formDeviceReboot.
Deeper analysisAI
CVE-2025-70219, published on 2026-03-04, is a stack buffer overflow vulnerability (CWE-121) in the D-Link DIR-513 router version 1.10. The flaw resides in the goform/formDeviceReboot web interface endpoint, which can be triggered remotely to overflow the stack.
The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical), with attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and unchanged scope (S:U). Remote attackers can exploit it without authentication to achieve high impacts on confidentiality (C:H), integrity (I:H), and availability (A:H), potentially enabling arbitrary code execution and full device compromise.
