Cisco Network Services Orchestrator Path Traversal Vulnerability

A vulnerability in the API subsystem and in the web-management interface of Cisco Network Services Orchestrator (NSO) could allow an unauthenticated, remote attacker to access sensitive data.
This vulnerability exists because the web-management interface and certain HTTP-based APIs do not properly validate user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the affected system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

CWE-35 Path Traversal: '.../...//'

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '.../...//' (doubled triple dot slash) sequences that can resolve to a location that is outside of that directory.
