Technical details

The vulnerability is an information disclosure issue (CWE-319) caused by insufficient access control enforcement for specific template types that are not included in the encryption allowlist in Cisco Catalyst SD-WAN Manager's web interface. A low-privileged, authenticated remote attacker can exploit this by viewing logs stored locally or on a remote logging server, exposing sensitive authentication credentials in clear text. No user interaction is required beyond authentication. The vulnerability affects all deployment types including on-premises, cloud-managed, and government deployments. Cisco has released patched versions across multiple release branches (e.g., 20.9.10, 20.12.8, 20.15.6, 20.18.4, 26.1.2, 26.2.1), and no workarounds are available.
