Operationally, ranked in the top 6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A vulnerability identified as CVE-2023-2376 affects the Web Management Interface component of Ubiquiti EdgeRouter X devices running firmware up to version 2.0.9-hotfix.6. The issue stems from improper handling of the dpi argument, enabling command injection as classified under CWE-77. It received a CVSS 3.1 score of 6.3 and was rated critical in public records, with the flaw residing in an unknown function of the interface.
The vulnerability can be exploited remotely by an authenticated user with low privileges. Successful manipulation of the dpi parameter allows an attacker to inject and execute arbitrary commands, resulting in limited impacts to confidentiality, integrity, and availability without requiring user interaction.
Public references include exploit code disclosed on GitHub along with entries on Vuldb, confirming that working proof-of-concept material has been released. The associated EPSS score remains flat at a peak and current value of 0.1373, indicating no material increase in observed exploitation interest following disclosure. No official patch or mitigation details appear in the provided references.

Mitigating Controls
Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Developer assessments and testing (including injection-focused techniques) identify improper neutralization of special elements, and the verifiable flaw remediation corrects them pre-deployment.
Identifies indicators of injection attacks (command, SQL, LDAP, etc.) via anomaly and attack monitoring.
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.
Logging supports detection of injection attempts but does not prevent the weakness.
Monitoring activities can identify active injection attacks after they occur.
A.8.25 mandates a secure SDLC process that includes secure coding guidelines, security requirements, checkpoints, testing (scans/penetration), and developer training to reduce injection flaws, but does not itself enforce or guarantee neutralization of special elements at runtime.
Application security requirements explicitly call for controls against injection attacks in software design.
A.8.27 mandates security-by-design principles (including distrust external input, data validation/sanitization, secure architecture layers, and design reviews against attack patterns) that reach injection when applied to output construction; this stops exploitation for a minority slice (e.g. where principles drive sanitization) but leaves most code-level injection defects untouched without further implementation rigor.
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.
