CVE-2023-2522
Command Injection in Feiyuxing Vec40G Firmware 3.0
Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/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-2023-2522 is a medium-severity OS Command Injection (CWE-78) vulnerability in Feiyuxing Vec40G Firmware. Its CVSS base score is 4.7 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 2% 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.
CVE-2023-2522 is an OS command injection vulnerability, tracked as CWE-78, that affects the Network Detection component of Chengdu VEC40G 3.0. The flaw resides in the file /send_order.cgi?parameter=access_detect, where the COUNT argument can be manipulated with input such as "3 | netstat -an" to execute arbitrary operating-system commands.
An attacker with administrative credentials can launch the attack remotely over the network. Successful exploitation yields limited read, write, and availability impacts on the affected device, as reflected in the CVSS 4.7 base score.
Public references consist of disclosure entries on Vuldb and a GitHub repository containing exploit details; the vendor was notified prior to publication but provided no response or patch information.
The associated EPSS score rose from a low baseline to a peak of 0.2645 before receding to its current value of 0.1503, indicating measurable post-disclosure interest in the issue.

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).
