Security readout for executives and security teams
Plain-English summary
OMERO.server 5.4.0 through 5.4.6 had a user-management access control flaw. A restricted administrator could reset a more powerful administrator's password and then log in as that account, effectively bypassing intended privilege limits.
Executive priority
Prioritize remediation where OMERO.server is used for sensitive research data or has delegated administrators. This is not described as unauthenticated internet exploitation, but it can undermine administrative separation and data governance.
Technical view
CVE-2018-1000634 is an improper access control issue in OMERO.server user management. The CVE states that restricted administrative users could set passwords for higher-privileged administrators. The vulnerability was reported as fixed in OMERO.server 5.4.7.
Likely exposure
Exposure is limited to organizations running OMERO.server versions 5.4.0 to 5.4.6, especially where administrative duties are delegated to restricted administrators. The source bundle does not identify affected CPEs or other products.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. The attack requires user administration privilege, so the main concern is malicious or compromised restricted admin accounts escalating to stronger administrator access.
Researcher notes
The source bundle lacks CVSS, CWE, and detailed affected CPE metadata. Analysis is based on the CVE description and Open Microscopy references stating affected versions, privilege-escalation behavior, and the 5.4.7 fix.
Mitigation direction
- Upgrade OMERO.server to version 5.4.7 or later.
- Review vendor advisory 2018-SV3 for deployment-specific guidance.
- Audit restricted administrator accounts and delegated user-management privileges.
- Reset passwords for privileged administrators if misuse is suspected.
Validation and detection
- Inventory OMERO.server instances and confirm exact versions.
- Identify any systems running versions 5.4.0 through 5.4.6.
- Review administrative role assignments and password-change audit records.
- Confirm upgraded systems report OMERO.server 5.4.7 or later.
