Summary

CVE-2025-9387 is a low-severity Command Injection (CWE-77) vulnerability in Dcnetworks Dcme-720 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.

Deeper analysis AI-assisted summary

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

CVE-2025-9387 is an OS command injection vulnerability affecting the DCN DCME-720 appliance at firmware version 9.1.5.11. It resides in an unspecified function of the file /usr/local/www/function/audit/newstatistics/ip_block.php within the Web Management Backend component and stems from insufficient sanitization of the ip argument, corresponding to CWE-77 and CWE-78.

An authenticated remote attacker with low-privileged access can supply a crafted ip value to the endpoint and execute arbitrary operating system commands. The attack is network-reachable with low complexity and no user interaction required, producing limited effects on confidentiality, integrity, and availability per the CVSS 2.1 rating.

Public proof-of-concept code has been published on GitHub, and the vendor was contacted prior to disclosure but did not respond. The associated EPSS score has remained flat at 0.0125 with no material rise after publication.

Mitigating Controls (NIST 800-53 r5) AI

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

Input validation directly stops construction of commands from untrusted data containing special elements.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

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

PR.PS-06 mostly match
blocks

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
blocks

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).

finds

Security testing in development catches command-injection vulnerabilities before release.

prevents

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

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-77, a class-level weakness, and none of its children carries one either.
