CVE-2025-23407 Overview
CVE-2025-23407 is an incorrect privilege assignment vulnerability [CWE-266] in the Web UI setting page of the Inaba Wi-Fi AP UNIT AC-WPS-11ac series. Authenticated remote attackers who log in to the product can alter settings without holding the required privileges. The flaw allows a low-privileged account to perform configuration changes that should be restricted to higher-privileged roles. Successful exploitation can affect the integrity of the device configuration, though confidentiality and availability are not directly impacted according to the published scoring.
Critical Impact
An authenticated attacker with low privileges can modify Wi-Fi access point settings without appropriate authorization, potentially weakening network security posture.

Technical Details for CVE-2025-23407
Vulnerability Analysis
The vulnerability resides in the Web UI setting page of the AC-WPS-11ac series Wi-Fi access points. The device fails to correctly enforce privilege boundaries between authenticated user roles. An attacker who has valid credentials, even at a lower privilege tier, can invoke settings-modification functions that should be reserved for administrators.
The issue is classified under CWE-266: Incorrect Privilege Assignment. This category covers cases where a product assigns a privilege or a permission to a user or process that is not the correct or intended privilege for that actor. In practical terms, the Web UI likely performs authentication checks but omits or mis-implements per-endpoint authorization checks.
Exploitation requires network access to the management interface and valid login credentials. No user interaction is needed after login. The attack impacts configuration integrity, which can indirectly weaken the wireless network by permitting changes to SSID parameters, radio settings, or access control lists.
Root Cause
The root cause is a missing or insufficient authorization check on privileged setting endpoints exposed through the Web UI. The application appears to rely on authentication as the sole gate, without validating whether the authenticated session holds the role required to execute the requested action.
Attack Vector
The attack is delivered over the network to the device management interface. The attacker must first log in with any valid account, then issue requests to setting-modification endpoints that should require higher privileges. See the JVN Vulnerability Report and the Inaba Security Advisory PDF for vendor-supplied technical details.
No public proof-of-concept exploit has been published, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-23407
Indicators of Compromise
- Unexpected configuration changes on AC-WPS-11ac series access points, including SSID, radio, or authentication parameter modifications
- Web UI session activity from low-privileged accounts followed by administrative-level setting changes
- Configuration audit logs showing setting updates that do not correlate with authorized administrator activity
Detection Strategies
- Compare running device configuration against a known-good baseline at regular intervals to detect unauthorized drift
- Enable and forward Web UI access and audit logs to a centralized log management or SIEM platform for correlation
- Alert on any HTTP request to setting-modification endpoints originating from accounts not assigned an administrator role
Monitoring Recommendations
- Monitor authentication events on the access point management interface for unusual account activity or brute-force attempts
- Track configuration file hashes to detect silent changes to device settings
- Review network segmentation between user VLANs and the AP management network to restrict who can reach the Web UI
How to Mitigate CVE-2025-23407
Immediate Actions Required
- Apply the firmware update referenced in the Inaba Security Advisory PDF as soon as it is available for your model
- Restrict access to the Web UI management interface to trusted administrative networks only
- Rotate credentials on all AC-WPS-11ac accounts and remove any unnecessary low-privileged user accounts
- Audit current device configurations against a known-good baseline and revert any unauthorized changes
Patch Information
Inaba Denki Sangyo published a security advisory on April 4, 2025 covering this issue. Refer to the Inaba Security Advisory PDF and the JVN Vulnerability Report for the list of fixed firmware versions and update instructions for the AC-WPS-11ac series.
Workarounds
- Place the access point management interface behind a firewall or management VLAN reachable only by administrators
- Enforce strong, unique passwords on every device account and disable accounts that are not required
- Disable remote management from untrusted networks and require VPN access for administrative sessions
- Monitor device configuration for unauthorized modifications until firmware updates can be applied
