Vulnerability Description A directory traversal vulnerability in Cisco Catalyst SD-WAN Manager allows an authenticated, remote attacker to create or overwrite any file on the filesystem of an affected system. This vulnerability exists because the affected software does not properly validate user-supplied input during a file upload process. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected API endpoint of the affected system. A successful exploit could allow the attacker to create or overwrite any file on the underlying operating system, potentially leading to privilege escalation.
