CISA KEV Advisory
Netis WF2419 Devices Remote Code Execution Vulnerability
Netis WF2419 devices contains an unspecified vulnerability that allows an attacker to perform remote code execution as root through the router's web management page.
Apply updates per vendor instructions.
Risk Analysis
An unspecified vulnerability in Netis WF2419 devices allows for remote code execution with root privileges through the web management page. This is a high-severity flaw with a very high exploitation likelihood (EPSS 0.91088). Its inclusion in CISA's KEV catalog indicates confirmed exploitation.
This vulnerability is actively being exploited in the wild. Attackers can achieve remote code execution as root, indicating a significant risk of full system compromise.
It is critical to update Netis WF2419 devices to a patched version if available. If updates are not available, restrict access to the router's web management page to trusted networks only.
Technical Analysis
CVE-2019-19356 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2019-19356 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
