Summary
CVE-2025-70222 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
Directly enforces validation of the curTime parameter at login endpoints to prevent stack buffer overflows from malformed input.
Implements stack canaries and memory protections to detect and block exploitation of the stack buffer overflow vulnerability.
Mandates timely remediation of the specific stack buffer overflow flaw in D-Link DIR-513 firmware via vendor patches.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The vulnerability is a remotely exploitable stack buffer overflow in a public-facing web interface (/goform endpoints) on a router, enabling unauthenticated arbitrary code execution, directly mapping to Exploitation of Public-Facing Application.
NVD Description
Stack buffer overflow vulnerability in D-Link DIR-513 v1.10 via the curTime parameter to goform/formLogin,goform/getAuthCode.
Deeper analysisAI
CVE-2025-70222 is a stack buffer overflow vulnerability (CWE-121) in D-Link DIR-513 router version 1.10. The flaw occurs via the curTime parameter sent to the /goform/formLogin or /goform/getAuthCode endpoints, potentially leading to buffer overrun conditions during processing.
The vulnerability 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), indicating it is exploitable over the network with low attack complexity, requiring no privileges or user interaction. Remote unauthenticated attackers can trigger the overflow, achieving high impacts on confidentiality, integrity, and availability, such as arbitrary code execution and complete router compromise.
