Detailsinfo

A vulnerability, which was classified as critical, was found in Cisco Catalyst SD-WAN Manager. This affects some unknown processing of the component Web-based Management Interface. 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. The summary by CVE is:

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to conduct a directory traversal attack and obtain read access to sensitive files on an affected system.
