CISA KEV Advisory
NETGEAR Multiple WAP Devices Command Injection Vulnerability
Multiple NETGEAR Wireless Access Point devices allows unauthenticated web pages to pass form input directly to the command-line interface. Exploitation allows for arbitrary code execution.
Apply updates per vendor instructions.
Risk Analysis
Multiple NETGEAR Wireless Access Point devices are vulnerable to arbitrary code execution due to unauthenticated web pages passing input directly to the command-line interface. With an EPSS score of 0.94122 and confirmed exploitation by CISA, this is a critical vulnerability with a high likelihood of active exploitation.
This vulnerability is actively being exploited in the wild. Attackers can remotely execute arbitrary code on affected devices without authentication.
Update NETGEAR Wireless Access Point devices to the latest firmware versions. Implement network segmentation and restrict access to administrative interfaces.
Technical Analysis
CVE-2016-1555 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-2016-1555 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.
