CVE-2019-19356
RCE in Netis-Systems Wf2419 Firmware 1.2.31805 … 2.2.36123
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2019-19356 is a high-severity OS Command Injection (CWE-78) vulnerability in Netis-Systems Wf2419 Firmware. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities 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.
Netis WF2419 routers running firmware versions V1.2.31805 and V2.2.36123 contain an authenticated remote code execution vulnerability in the web management interface. The flaw, tracked as CVE-2019-19356 and assigned CWE-78, stems from missing sanitization of user input passed to the tracert diagnostic tool, allowing system commands to be executed with root privileges. The issue carries a CVSS 3.1 score of 7.5 reflecting network attack vector, high attack complexity, and low privileges required.
An attacker who has obtained valid credentials for the router's administrative web page can submit crafted input through the tracert function to run arbitrary commands as root. Successful exploitation grants full control of the device, including the ability to modify configuration, intercept traffic, or pivot to other systems on the local network.
Public proof-of-concept code and technical write-ups are available that demonstrate the attack against the affected firmware versions, though no vendor advisory or patch information is referenced in the available sources.

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).
