high Nessus Plugin ID 131327

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, Cisco IOS XE Software is affected by a privilege escalation vulnerability in the web-based Wireless Controller GUI for Cisco 5760 Wireless LAN Controllers, Cisco Catalyst 4500E Supervisor Engine 8-E (Wireless) Switches, and Cisco New Generation Wireless Controllers (NGWC) 3850. This is due to incomplete input validation of HTTP requests by the affected GUI, if the GUI connection state or protocol changes. An authenticated, remote attacker can exploit this by authenticating with the Wireless Controller GUI as a Lobby Administrator user of an affected device and then changing the state or protocol for their connection to the GUI. Successful exploitation of this vulnerability would allow an attacker to elevate their privilege level to administrator to gain full control of the affected device.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID(s) CSCvd73746.
