A vulnerability was found in Cisco Wireless LAN Controller Software (Wireless LAN Software) (the affected version is unknown). It has been declared as problematic. This vulnerability affects an unknown code of the component Web-based Interface. The manipulation as part of a HTTP Request leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The bug was discovered 10/17/2018. The weakness was published 10/17/2018 as cisco-sa-20181017-wlc-traversa as confirmed advisory (Website). The advisory is available at tools.cisco.com.
