CVE-2025-11126: Apeman ID71 Auth Bypass Vulnerability

CVE-2025-11126 Overview

A security vulnerability has been discovered in the Apeman ID71 IP camera (firmware version 218.53.203.117) involving hard-coded credentials embedded within the device firmware. This vulnerability affects the configuration file located at /system/www/system.ini, allowing remote attackers to potentially gain unauthorized access to the device without proper authentication.

The flaw enables attackers to leverage pre-configured credentials that cannot be changed by end users, effectively bypassing authentication mechanisms. The vendor was contacted early about this disclosure but did not respond, leaving devices without an official patch.

Critical Impact
Remote attackers can exploit hard-coded credentials to gain complete control over affected Apeman ID71 IP cameras, potentially enabling surveillance, network pivoting, or participation in IoT botnets.

Technical Details for CVE-2025-11126

Vulnerability Analysis

This vulnerability falls under CWE-259 (Use of Hard-coded Password), a common weakness in IoT and embedded devices where manufacturers embed static credentials directly into firmware for convenience during development or manufacturing. These credentials persist in production devices and cannot be modified by end users.

The vulnerability is network-accessible, requiring no user interaction or special privileges to exploit. Once an attacker identifies an exposed Apeman ID71 device, they can leverage the hard-coded credentials to authenticate and gain full access to device functionality.

The exploitation of this vulnerability has been publicly disclosed, increasing the risk to unpatched devices. IoT cameras are particularly attractive targets as they can be incorporated into botnets, used for unauthorized surveillance, or serve as pivot points for further network intrusion.

Root Cause

The root cause is the inclusion of hard-coded credentials within the /system/www/system.ini configuration file. This represents a fundamental security design flaw where authentication credentials are embedded directly in the firmware rather than being dynamically generated or user-configurable during initial setup.

This approach violates security best practices by:

Eliminating the ability for users to change default credentials
Creating a single point of failure across all deployed devices
Enabling mass exploitation once credentials are discovered

Attack Vector

The attack vector is network-based, allowing remote exploitation without any authentication or user interaction. An attacker can discover vulnerable devices through internet scanning services or targeted network reconnaissance.

The exploitation process involves identifying exposed Apeman ID71 devices on the network and then using the hard-coded credentials found in the system.ini file to authenticate to the device's web interface or other management services. Once authenticated, the attacker gains full administrative control over the camera.

Detection Methods for CVE-2025-11126

Indicators of Compromise

Unexpected authentication attempts to Apeman ID71 devices from external IP addresses
Successful logins to camera management interfaces from unrecognized sources
Unusual network traffic patterns originating from IP cameras
Modified device configurations or firmware without administrator action

Detection Strategies

Monitor network traffic for connections to Apeman ID71 devices from untrusted networks
Implement network segmentation to isolate IoT devices and monitor cross-segment traffic
Deploy intrusion detection rules to alert on access attempts to /system/www/system.ini
Review authentication logs for any successful remote access to camera devices

Monitoring Recommendations

Establish baseline network behavior for IoT cameras and alert on deviations
Implement continuous asset discovery to identify exposed Apeman devices on the network
Configure SIEM alerts for authentication events on IoT device management interfaces
Conduct regular vulnerability scans targeting IoT and embedded devices

How to Mitigate CVE-2025-11126

Immediate Actions Required

Isolate affected Apeman ID71 cameras on a segmented network with restricted internet access
Implement firewall rules to block external access to camera management interfaces
Consider replacing vulnerable devices with cameras from vendors that follow security best practices
Audit network for all Apeman ID71 devices and document their exposure

Patch Information

No official patch is currently available from the vendor. According to the disclosure, the vendor was contacted early about this vulnerability but did not respond. Users should monitor vendor communications for any future firmware updates.

For additional technical details, refer to:

Workarounds

Place all affected cameras behind a firewall that blocks inbound connections from untrusted networks
Use a VPN to access camera feeds remotely rather than exposing devices directly to the internet
Implement network access control (NAC) to restrict which devices can communicate with the cameras
Deploy network monitoring to detect any unauthorized access attempts to affected devices
