An issue was discovered in the changePassword method in file /usr/share/php/openmediavault/system/user.inc in OpenMediaVault 7.4.17 allowing local authenticated attackers to escalate privileges to root.
Security readout for executives and security teams
Plain-English summary
CVE-2025-50674 is a local privilege escalation issue in OpenMediaVault 7.4.17. A low-privileged authenticated local attacker could reportedly gain root privileges through the changePassword method. This is serious for shared, multi-user, or weakly administered NAS systems, but the provided sources do not show remote exploitation or active exploitation in the wild.
Executive priority
Prioritize this for OpenMediaVault systems with multiple users or weak local account governance. It is not described as remote or actively exploited, but root escalation can turn a limited foothold into full system compromise.
Technical view
The issue is reported in /usr/share/php/openmediavault/system/user.inc, specifically the changePassword method. The CVE assigns CVSS 3.1 score 7.8 with AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, mapped to CWE-20 and CWE-269. The normalized affected product metadata is incomplete, but the description names OpenMediaVault 7.4.17.
Likely exposure
Exposure is most likely on OpenMediaVault 7.4.17 systems where local authenticated users exist or where low-privileged accounts are not tightly controlled. The source bundle does not provide CPEs or a complete affected-version range, so teams should verify against vendor guidance.
Exploitation context
The provided CVE data says exploitation requires local access and low privileges, with no user interaction. CISA KEV status is false, and the supplied sources do not establish active exploitation. Public researcher references exist, so defenders should treat technical details as publicly discoverable.
Researcher notes
The evidence is useful but incomplete: the CVE description names OpenMediaVault 7.4.17, while affected vendor/product/version fields are listed as n/a. Do not assume broader version impact without vendor confirmation. Avoid relying on public PoC material for validation beyond defensive assessment.
Mitigation direction
Check OpenMediaVault vendor guidance for a fixed release or official workaround.
Apply vendor-published security updates once confirmed for affected systems.
Restrict local and shell access to trusted administrative users only.
Remove stale, shared, or unnecessary authenticated accounts from OMV hosts.
Monitor privileged account changes and unexpected password-management activity.
Validation and detection
Inventory OpenMediaVault hosts and identify any running version 7.4.17.
Confirm whether low-privileged local users can authenticate to affected hosts.
Review vendor advisories and release notes for affected-version clarification.
Check system logs for unexpected password changes or privilege changes.
Verify compensating access controls around local accounts and administrative access.
