CVE-2021-1304Network attack vector

Sensitive-information access via unchecked SSH console authorization

Published Jan 20, 2021 · Updated Nov 12, 2024

Authorization bypass in Cisco Catalyst SD-WAN Manager allows remote authenticated users to read sensitive data through its SSH console. The web management interface's SSH console performs insufficient authorization checks before exposing information beyond the account's assigned privileges. A valid web account and use of the SSH console are required; the disclosed impact is sensitive-information access that supports further attacks.
