CVE-2023-4711
Published: 01 September 2023
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 Exploit Public-Facing Application (T1190); ranked in the top 40.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
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.
