CVE-2017-3854

CVE-2017-3854

A vulnerability in the mesh code of Cisco Wireless LAN Controller (WLC) software could allow an unauthenticated, remote attacker to impersonate a WLC in a meshed topology. The vulnerability is due to insufficient authentication of the parent access point in a mesh configuration. An attacker could exploit this vulnerability by forcing the target system to disconnect from the correct parent access point and reconnect to a rogue access point owned by the attacker. An exploit could allow the attacker to control the traffic flowing through the impacted access point or take full control of the target system. This vulnerability affects the following products running a vulnerable version of Wireless LAN Controller software and configured for meshed mode: Cisco 8500 Series Wireless Controller, Cisco 5500 Series Wireless Controller, Cisco 2500 Series Wireless Controller, Cisco Flex 7500 Series Wireless Controller, Cisco Virtual Wireless Controller, Wireless Services Module 2 (WiSM2). Note that additional configuration is needed in addition to upgrading to a fixed release. Cisco Bug IDs: CSCuc98992 CSCuu14804.

CVE-2017-3831

CVE-2017-3831

A vulnerability in the web-based GUI of Cisco Mobility Express 1800 Series Access Points could allow an unauthenticated, remote attacker to bypass authentication. The attacker could be granted full administrator privileges. The vulnerability is due to improper implementation of authentication for accessing certain web pages using the GUI interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web interface of the affected system. A successful exploit could allow the attacker to bypass authentication and perform unauthorized configuration changes or issue control commands to the affected device. This vulnerability affects Cisco Mobility Express 1800 Series Access Points running a software version prior to 8.2.110.0. Cisco Bug IDs: CSCuy68219.
