A vulnerability in the application data endpoints of Cisco SD-WAN vManage Software could allow an unauthenticated, remote attacker to gain access to sensitive information.
The vulnerability is due to improper validation of directory traversal character sequences within requests to application programmatic interfaces (APIs). An attacker could exploit this vulnerability by sending malicious requests to an API within the affected application. A successful exploit could allow the attacker to conduct directory traversal attacks and gain access to sensitive information including credentials or user tokens.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

- →Exploit requests use URL-encoded directory traversal sequences (%2E%2E%2F or ../) immediately following the /dataservice/disasterrecovery/download/token/ path prefix in a GET request. ↗
- →Successful exploitation of /etc/passwd read will return a response body matching the pattern 'root:.*:0:0:', which can be used as a response-based detection signal. ↗
- →The attack targets the unauthenticated API endpoint /dataservice/disasterrecovery/download/token/ — monitor for GET requests to this path from external/untrusted sources with no session token. ↗
- →MITRE mapping: TA0007 (Discovery) / T1083 (File and Directory Discovery) — correlate with file-read activity on vManage hosts. ↗
- ·The vulnerability is exploitable without authentication — no session cookie or token is required, so absence of auth headers should not be used to filter out suspicious requests to this endpoint. ↗
- ·Sensitive data exposed includes credentials and user tokens, not just static files — post-exploitation impact extends beyond file read to full credential compromise. ↗
- ·Cisco confirmed no workarounds exist; detection/blocking at the perimeter is the only mitigation until patching is applied. ↗
