CVE-2025-27258
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedEricsson Network Manager (ENM) versions prior to ENM 25.1 GA contain a vulnerability, if exploited, can result in an escalation of privilege.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceEricsson Network Manager (ENM) versions prior to 25.1 GA contain a privilege escalation vulnerability allowing an attacker to gain higher-level access than originally provided. The critical CVSS score of 9.8 indicates this can likely be exploited remotely without authentication, potentially giving administrative control over the network management system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify ENM versionLog into the Ericsson Network Manager CLI or web interface and navigate to the version or system information section. Alternatively, run the command 'enmpkg -l' or check '/opt/enm/version' if such paths are standard on your system.Affected if The displayed version is any build prior to 25.1 GA (for example, 24.x, 23.x, or earlier).
-
Verify management interface exposureReview your network configuration to determine whether ENM management ports (typically HTTPS ports 443, 8443, or proprietary ENM ports) are accessible from untrusted networks or the public internet. Use firewall rules or network scans to confirm external accessibility.Affected if The ENM web interface or CLI ports are reachable from outside your trusted network without VPN or jump host restrictions.
-
Confirm user authentication settingsCheck the ENM user directory configuration to see which authentication mechanisms are enabled (local accounts, LDAP, TACACS+, RADIUS). Review whether default administrative accounts still exist with default credentials.Affected if Multiple authentication methods are enabled simultaneously, or default admin accounts with unchanged passwords are present in the system.
You are affected if your Ericsson Network Manager installation shows a version number below 25.1 GA and the management interface is network-accessible.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped25.1
Upgrade Ericsson Network Manager to version 25.1 GA or later. Prior to upgrade, restrict network exposure of ENM interfaces and implement strong access controls to reduce attack surface.
ENM 25.1 GA
- 1. Contact Ericsson support or access the Ericsson support portal to obtain the ENM 25.1 GA upgrade package
- 2. Follow Ericsson's official upgrade documentation and procedures for Ericsson Network Manager
- 3. Upgrade your ENM deployment to version 25.1 GA
- 4. Verify the upgrade was successful and the vulnerability is remediated
