CVE-2026-2000 — DCN DCME-320 Web Management Backend bridge_cfg.php apply_config command injection

A vulnerability was found in DCN DCME-320 up to 20260121. Impacted is the function apply_config of the file /function/system/basic/bridge_cfg.php of the component Web Management Backend. Performing a manipulation of the argument ip_list results in command injection. The attack is possible to be carried out remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 19.7% (30-day exploitation probability)+15
  • Technical severity (high)+6
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (DCN DCME-320, Dcnetworks Dcme-320 Firmware).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. EPSS ahead of 97% of scored CVEs: prioritize it in the patch queue.
  4. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

What should defenders know first?

CVE-2026-2000 is "DCN DCME-320 Web Management Backend bridge_cfg.php apply_config command injection", rated High. It affects DCME-320 (DCN); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.2 describes technical severity. EPSS 19.73% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
