Directory traversal vulnerability on the Emerson Network Power Avocent MergePoint Unity 2016 (aka MPU2016) KVM switch with firmware 1.9.16473 allows remote attackers to read arbitrary files via unspecified vectors, as demonstrated by reading the /etc/passwd file.
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.
