Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The vulnerability CVE-2017-6862 is a buffer overflow in the administration web application of certain NETGEAR routers that enables authentication bypass and remote code execution. It affects WNR2000v3 devices running firmware versions prior to 1.1.2.14, WNR2000v4 devices before 1.0.0.66, and WNR2000v5 devices before 1.0.0.42, as identified under NETGEAR PSV-2016-0261 and classified under CWE-120.
An unauthenticated attacker can exploit this flaw over the network by supplying a specially crafted parameter to the web interface, achieving full remote code execution with the ability to compromise the device's confidentiality, integrity, and availability, corresponding to a CVSS score of 9.8.
NETGEAR has released firmware updates addressing the issue, with the security advisory recommending that users upgrade to the fixed versions specified for each model to mitigate the risk of unauthenticated remote code execution.
