Summary

CVE-2025-70231 is a critical-severity Path Traversal (CWE-22) 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 49th 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 AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2025-70231, published on 2026-03-05, is a critical path traversal vulnerability (CWE-22) in D-Link DIR-513 version 1.10. The flaw arises when the device processes POST requests related to verification codes via the /goform/formLogin endpoint, which forwards to /goform/getAuthCode without properly filtering the FILECODE parameter. This allows traversal outside intended directories. 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).

Remote attackers can exploit this vulnerability over the network with low attack complexity, requiring no authentication privileges or user interaction. Exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially allowing arbitrary file read, write, or execution depending on the traversed paths.

Mitigation guidance and patches are referenced in vendor advisories, including D-Link's 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 detailed report at https://github.com/akuma-QAQ/CVEreport/tree/main/D-link/CVE-2025-70231.

Vulnerability Data

D-Link DIR-513 version 1.10 contains a critical-level vulnerability. When processing POST requests related to verification codes in /goform/formLogin, it enters /goform/getAuthCode but fails to filter the value of the FILECODE parameter, resulting in a path traversal vulnerability.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

SI-10 Information Input Validation good match

Input validation directly neutralizes special path elements before pathname construction occurs.

AC-6 Least Privilege partial match

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches path traversal via static/dynamic analysis.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules for safe file handling and canonicalization.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles require least-privilege file access and directory isolation.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits which files an application may read or write.
