CVE-2025-1882: I-drive I11 Auth Bypass Vulnerability

CVE-2025-1882 Overview

CVE-2025-1882 affects i-Drive i11 and i12 devices through firmware version 20250227. The flaw resides in the Device Setting Handler component and stems from improper access control on the register interface [CWE-284]. An attacker on the adjacent network can manipulate device settings without proper authorization checks. The vendor appears unreachable, and the product is presumed end-of-life, meaning an official patch is unlikely. Exploitation requires high attack complexity and is considered difficult to achieve in practice.

Critical Impact
Adjacent network attackers can manipulate device register settings due to missing access control checks in the Device Setting Handler, with no vendor patch expected.

Affected Products

i-Drive i11 firmware up to 20250227
i-Drive i12 firmware up to 20250227
i-Drive i11 and i12 hardware devices running affected firmware

Technical Details for CVE-2025-1882

Vulnerability Analysis

The vulnerability resides in the Device Setting Handler component of i-Drive i11 and i12 devices. The register interface fails to enforce proper access control on requests that modify device settings. An attacker positioned on the same local network segment can send crafted requests to the register interface and alter configuration without proving authorization. The issue is classified under [CWE-284] Improper Access Control. Because the product is assumed end-of-life and the maintainer cannot be identified, affected devices will likely remain unpatched indefinitely.

Root Cause

The register interface within the Device Setting Handler does not validate the requester's identity or privilege level before processing setting changes. This missing authorization check allows any reachable client on the adjacent network to invoke privileged configuration operations. The flaw is a design-level access control gap rather than a memory safety or injection issue.

Attack Vector

Exploitation requires adjacent network access, meaning the attacker must reside on the same broadcast domain or local network segment as the target device. No authentication and no user interaction are required. However, attack complexity is rated high, indicating that successful exploitation depends on conditions outside the attacker's direct control. The confidentiality, integrity, and availability impacts are each rated low. Technical details and proof-of-concept information are referenced through the GitHub Repository for i-Drive and VulDB entry #298196.

Detection Methods for CVE-2025-1882

Indicators of Compromise

Unexpected configuration changes on i-Drive i11 or i12 devices, including modified register values applied without administrator action.
Inbound traffic to the Device Setting Handler interface originating from unauthorized hosts on the local network.
Device reboots, role changes, or service interruptions following local network access from new or unmanaged endpoints.

Detection Strategies

Monitor LAN traffic destined for i-Drive i11 and i12 management interfaces and alert on register-modifying requests from non-administrative sources.
Baseline normal device configuration and trigger alerts when register values or device settings deviate from the approved baseline.
Capture and inspect management protocol traffic between clients and i-Drive devices to identify unauthenticated setting changes.

Monitoring Recommendations

Log all access attempts to i-Drive device administrative interfaces and forward those logs to a centralized SIEM for correlation.
Track adjacent network endpoints communicating with i-Drive devices and flag new or unmanaged MAC or IP addresses.
Review device configuration audit trails on a recurring schedule to detect unauthorized register interface changes.

How to Mitigate CVE-2025-1882

Immediate Actions Required

Isolate affected i-Drive i11 and i12 devices on a dedicated VLAN with strict access control lists limiting which hosts can reach the management interface.
Inventory all i-Drive i11 and i12 deployments to determine exposure and prioritize replacement planning.
Block access to the Device Setting Handler interface from any host that does not require administrative connectivity.

Patch Information

No vendor patch is available. The maintainer of i-Drive could not be identified, and the product is presumed end-of-life. Organizations should treat affected devices as permanently vulnerable and plan migration to a supported platform. Refer to the VulDB advisory for the authoritative vulnerability record.

Workarounds

Place affected devices behind a firewall that restricts adjacent network access to a small, defined set of administrative hosts.
Disable the register interface or Device Setting Handler if device functionality permits, removing the exposed attack surface.
Replace end-of-life i-Drive i11 and i12 devices with vendor-supported alternatives that receive ongoing security maintenance.

bash

# Example: restrict access to the i-Drive management interface using iptables
# Allow only the administrator workstation 192.0.2.10 to reach the device at 192.0.2.50
iptables -A FORWARD -s 192.0.2.10 -d 192.0.2.50 -j ACCEPT
iptables -A FORWARD -d 192.0.2.50 -j DROP
