CVE-2018-0420
A vulnerability in the web-based interface of Cisco Wireless LAN Controller Software could allow an authenticated, remote attacker to view sensitive information.
Does this matter?
Lower severity and a low EPSS score (4.64%). Track it; it rarely justifies an emergency change on its own.
Description
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.
