Missing authorization in Juniper Security Director 24.4.1 allows remote attackers to read or tamper with sensitive web resources. Multiple web-interface endpoints return or modify resources without validating the caller's authorization for those resources. No authentication is required, and exposed data can enable further access or attacks against downstream managed devices.
