Summary

CVE-2025-10629 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 8% 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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-10629 is a command injection vulnerability affecting the D-Link DIR-852 router on firmware version 1.00CN B09. The flaw exists in the ssdpcgi_main function within the htodcs/cgibin file of the Simple Service Discovery Protocol (SSDP) Service component. Manipulation of the ST argument enables arbitrary command execution, as detailed in the CVE description published on 2025-09-18.

The vulnerability allows remote exploitation over the network (AV:N) with low attack complexity (AC:L), requiring low privileges (PR:L) and no user interaction (UI:N), while maintaining an unchanged impact scope (S:U). Successful exploitation yields low confidentiality, integrity, and availability impacts (C:L/I:L/A:L), scored at CVSS 6.3 under CVSS:3.1 and mapped to CWEs-74 and CWE-77. Attackers with initial low-privilege access can inject commands to further compromise the device.

Advisories from VulDB and a GitHub issue (i-Corner/cve#30) confirm the exploit is publicly disclosed and usable, with no patches available as the product is no longer supported by D-Link. Mitigation involves isolating affected devices from untrusted networks or decommissioning them, per the maintainer's end-of-support status.

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.
