Cisco Wireless LAN Controller Software Directory Traversal Vulnerability

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.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
