CVE-2023-4711
Command Injection in Dlink Dar-8000-10 Firmware ≤ 20230819
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:LCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-4711 is a medium-severity OS Command Injection (CWE-78) vulnerability in Dlink Dar-8000-10 Firmware. Its CVSS base score is 5.0 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); 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 critical OS command injection vulnerability (CWE-78) affects the D-Link DAR-8000-10 device up to firmware version 20230819. The flaw resides in an unknown function within /log/decodmail.php, where unsanitized input to the file argument permits arbitrary operating-system command execution. The issue received a CVSS v3.1 score of 5.0 (AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L) and was publicly disclosed under VDB-238574 after the vendor failed to respond to early notification.
An authenticated remote attacker can exploit the weakness over the network, though successful exploitation requires high attack complexity and is described as difficult. Successful abuse yields limited read, write, and disruption capabilities on the affected appliance; a working proof-of-concept has been published and may be reused by determined adversaries.
Public references consist of exploit code on GitHub and detailed entries on Vuldb; no vendor advisory, patch, or mitigation guidance has been issued. The EPSS score rose sharply from a low baseline to a peak of 0.1501 on 2025-01-22 before receding to 0.0037, indicating a clear post-disclosure increase in exploitation interest that warrants renewed monitoring.

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.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
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.
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).
