AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
NETGEAR NMS300 before 1.6.0.27 is vulnerable to pre-authentication command injection, allowing unauthenticated remote code execution.
Vulnerability
NETGEAR NMS300, a network management system, is affected by a command injection vulnerability in firmware versions prior to 1.6.0.27. The flaw resides in an unspecified endpoint that accepts user-supplied input without proper sanitization, and is reachable without authentication [1].
Exploitation
An unauthenticated attacker with network access to the NMS300 device can exploit this vulnerability by sending specially crafted HTTP requests. No prior authentication or user interaction is required. The advisory classifies the attack vector as network-based with low complexity [1].
Impact
Successful exploitation allows the attacker to execute arbitrary operating system commands on the underlying system with elevated privileges. This leads to complete compromise of confidentiality, integrity, and availability (CVSS v3 score 9.8, Critical) [1].
Mitigation
The vulnerability is fixed in firmware version 1.6.0.27. NETGEAR strongly recommends upgrading to this version or later. No workaround is documented. The latest firmware can be obtained from NETGEAR Support [1].
