Detailsinfo

A vulnerability classified as problematic was found in Cisco Wireless LAN Controller (Wireless LAN Software) (affected version not known). Affected by this vulnerability is some unknown functionality of the component CLI. The manipulation as part of a Parameter 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. The summary by CVE is:

A vulnerability in the CLI of Cisco Wireless LAN Controller (WLC) Software could allow an authenticated, local attacker to view system files that should be restricted. This vulnerability is due to improper sanitization of user-supplied input in command-line parameters that describe filenames. 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 that may contain sensitive information.
