MongoDB credential disclosure via plaintext configuration

Published Sep 11, 2024 · Updated Sep 11, 2024

Cleartext credential storage in Cisco IOS XR Software allows local users to read PON Controller MongoDB credentials. The PonCntlInit.json configuration stores the MongoDB password in an unencrypted password field that local users can read. Low-privilege local access and an enabled Routed PON Controller are required; the exposed password permits access to the controller database.
