Summary

CVE-2025-10628 is a low-severity Injection (CWE-74) vulnerability in Dlink Dir-852 Firmware. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 5% of CVEs by exploit likelihood; 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.

CVE-2025-10628 is a command injection vulnerability (CWE-74, CWE-77) discovered in the D-Link DIR-852 router running firmware version 1.00CN B09. The flaw resides in unknown code within the file /htdocs/cgibin/hedwig.cgi, part of the Web Management Interface. Published on September 18, 2025, it carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), rated as medium severity.

The vulnerability can be exploited remotely by an attacker with low-privilege access (PR:L) to the Web Management Interface, requiring no user interaction. By performing manipulation on the affected endpoint, the attacker achieves command injection, potentially leading to limited impacts on confidentiality, integrity, and availability (C:L/I:L/A:L).

References including VulDB entries and a GitHub issue (i-Corner/cve#31) document the vulnerability, but note that it only affects products no longer supported by the maintainer, implying no official patches are available. The D-Link website is listed as a reference, though no specific mitigation guidance is detailed in the provided information.

An exploit for this vulnerability has been made public and could be used, increasing risk for exposed, end-of-life DIR-852 devices.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

Secure engineering principles include proper neutralization and safe command construction practices.
