Technical Description
Ericsson Network Manager (ENM) before 21.2 has incorrect access-control behavior (that only affects the level of access available to persons who were already granted a highly privileged role). Users in the same AMOS authorization group can retrieve managed-network data that was not set to be accessible to the entire group (i.e., was only set to be accessible to a subset of that group).
Remediation
Check the references section for vendor advisories and patches from ericsson. Update network_manager to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
