Detailsinfo

A vulnerability, which was classified as critical, has been found in Cisco Enterprise NFV Infrastructure Software (the affected version is unknown). Affected by this issue is an unknown code of the component CLI. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in the CLI of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to overwrite or read arbitrary files. The attacker would need valid administrator privilege-level credentials. This vulnerability is due to improper input validation of CLI command arguments. An attacker could exploit this vulnerability by using directory traversal techniques when executing a vulnerable command. A successful exploit could allow the attacker to overwrite or read arbitrary files on an affected device.
