CVE-2021-28488 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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).. EPSS estimates a 1.07% chance of exploitation in the next 30 days.
