Summary
CVE-2026-2000 is a medium-severity Injection (CWE-74) vulnerability in Dcnetworks Dcme-320 Firmware. Its CVSS base score is 5.1 (Medium).
Operationally, ranked in the top 3% 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-2026-2026-2000 is a command injection vulnerability affecting DCN DCME-320 firmware versions up to 20260121. The flaw resides in the apply_config function of the file /function/system/basic/bridge_cfg.php within the Web Management Backend component, where manipulation of the ip_list argument enables command injection. Published on 2026-02-06, it carries a CVSS v3.1 base score of 4.7 (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L) and maps to CWEs CWE-74 and CWE-77.
The vulnerability is exploitable remotely over the network with low complexity, though it requires high privileges (PR:H), such as those of an authenticated administrator. An attacker could manipulate the ip_list parameter during configuration operations to inject and execute arbitrary commands, potentially resulting in limited impacts to confidentiality, integrity, and availability.
Advisories from VulDB (e.g., https://vuldb.com/?ctiid.344548, https://vuldb.com/?id.344548) document the issue, while an exploit is publicly available in a GitHub repository (https://github.com/physicszq/Routers/tree/main/Dcme). The vendor was notified early but provided no response, leaving no official patches or mitigation guidance available.

Mitigating Controls
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.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development catches injection vulnerabilities before release.
Monitoring activities can identify active injection attacks after they occur.
Secure coding standards require proper neutralization of special elements, directly addressing CWE-74.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-74, a class-level weakness, and none of its children carries one either.
- No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
