A vulnerability in the web-based interface of Cisco Wireless LAN Controller Software could allow an authenticated, remot

A vulnerability in the web-based interface of Cisco Wireless LAN Controller Software could allow an authenticated, remote attacker to view sensitive information. The issue is due to improper sanitization of user-supplied input in HTTP request parameters that describe filenames and pathnames. An attacker could exploit this vulnerability by using directory traversal techniques to submit a path to a desired file location.

A successful exploit could allow the attacker to view system files on the targeted device, which may contain sensitive information.
