A vulnerability, which was classified as critical, was found in Cisco Prime Infrastructure and Evolved Programmable Network (Network Management Software) (affected version unknown). This affects an unknown functionality of the component Web-based Management Interface. The manipulation as part of a HTTP Request leads to a path traversal vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability in the web-based management interface of Cisco Prime Infrastructure and Cisco Evolved Programmable Network (EPN) Manager software could allow an authenticated, remote attacker to download and view files within the application that should be restricted. This vulnerability is due to improper sanitization of user-supplied input in HTTP request 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 application files that may contain sensitive information.
