Authenticated privilege escalation
Published Oct 13, 2025 · Updated Oct 13, 2025
Improper access control in Ericsson Network Manager before 25.1 allows remote authenticated users on an adjacent network to escalate privileges. Ericsson has not disclosed the affected component or the access-control operation that incorrectly authorizes the request. Exploitation requires adjacent-network access and an existing low-privilege account; the reported consequence is elevated access to confidential data.
