Detailsinfo

A vulnerability, which was classified as critical, was found in Cisco Nexus Dashboard. This affects an unknown code of the component Backup Restore. The manipulation with an unknown input 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 backup restore functionality of Cisco Nexus Dashboard could allow an authenticated, remote attacker to conduct a path traversal attack on an affected device. This vulnerability is due to insufficient validation of the contents of a backup file.
