CVE-2016-1206

TITLE

WN-GDN/R3 Series does not limit authentication attempts

Trust: 0.8

sources: JVNDB: JVNDB-2016-000061

DESCRIPTION

The WPS implementation on I-O DATA DEVICE WN-GDN/R3, WN-GDN/R3-C, WN-GDN/R3-S, and WN-GDN/R3-U devices does not limit PIN guesses, which allows remote attackers to obtain network access via a brute-force attack. WN-GDN/R3 Series provided by I-O DATA DEVICE, INC. does not limit authentication attempts. WN-GDN/R3 series provided by I-O DATA DEVICE, INC. is a wireless LAN router. WPS functionality in WN-GDN/R3 Series does not limit PIN authentication attempts, making it susceptible to brute force attacks. Takeshi Okamoto of Kanagawa Institute of Technology and Takaaki Minegishi reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.An unauthenticated attacker within wireless range of the device may perform a brute force attack to recover the PIN. Using the recovered PIN, the attacker may gain access to the network. WN-GDN/R3 Series Routers are prone to an authentication-bypass vulnerability. Successfully exploiting this issue may lead to further attacks. The following products are affected: WN-GDN/R3 WN-GDN/R3-S WN-GDN/R3-U WN-GDN/R3-C. There are security vulnerabilities in the WPS implementation of several IO DATA DEVICE products
