CVE-2025-11852: Apeman ID71 Auth Bypass Vulnerability

CVE-2025-11852 Overview

CVE-2025-11852 is a missing authentication vulnerability [CWE-287] affecting the Apeman ID71 IP camera. The flaw resides in an unknown function within the /onvif/device_service endpoint of the ONVIF Service component. Attackers can reach this endpoint over the network without any credentials, user interaction, or elevated privileges. A public exploit exists, and the vendor did not respond to disclosure attempts, leaving deployed devices exposed. The issue affects confidentiality of information returned by the ONVIF device service on the Apeman ID71 camera.

Critical Impact
Unauthenticated remote attackers can invoke ONVIF device service methods on affected Apeman ID71 cameras, exposing device information without authentication.

Affected Products

Apeman ID71 IP camera (as identified in the CVE record)
ONVIF Service component exposed via /onvif/device_service
Related Apeman camera firmware exposing the same ONVIF endpoint

Technical Details for CVE-2025-11852

Vulnerability Analysis

The Apeman ID71 camera exposes an Open Network Video Interface Forum (ONVIF) endpoint at /onvif/device_service. ONVIF is a Simple Object Access Protocol (SOAP) based specification used for interoperability between IP-based physical security devices. On the affected camera, the endpoint accepts requests without validating credentials. The vulnerability is classified under CWE-287, Improper Authentication.

The issue falls into the Authentication Bypass category. Because the ONVIF device service returns device metadata and management functions, unauthenticated access breaks the intended access control model. An attacker on the same network segment or one who can reach the device over the internet can query the service directly. The exploit has been published publicly, increasing the likelihood of opportunistic scanning.

Root Cause

The root cause is missing enforcement of ONVIF's WS-Security UsernameToken authentication on the /onvif/device_service handler. ONVIF specifies that management operations require authenticated SOAP requests, but the camera firmware processes requests without verifying credentials. This design flaw permits anonymous callers to invoke device service methods.

Attack Vector

The attack vector is network based and requires no privileges or user interaction. An attacker sends crafted SOAP requests directly to the /onvif/device_service endpoint on the camera's HTTP interface. Public proof-of-concept material referenced in the GitHub PoC for APEMAN Camera and VulDB #328798 - Details illustrate related unauthenticated access patterns on Apeman devices.

See the linked references for technical details on the exact SOAP requests and endpoints involved. No verified exploit code is reproduced here.

Detection Methods for CVE-2025-11852

Indicators of Compromise

Unauthenticated HTTP POST requests to /onvif/device_service originating from unexpected internal or external sources
SOAP request bodies referencing ONVIF actions such as GetDeviceInformation, GetCapabilities, or GetSystemDateAndTime without a WS-Security header
Repeated ONVIF discovery probes on User Datagram Protocol (UDP) port 3702 followed by direct device service calls

Detection Strategies

Inspect network traffic to camera subnets for SOAP requests to /onvif/device_service lacking a wsse:UsernameToken element in the header
Correlate camera HTTP access logs, when available, with the source Internet Protocol (IP) address list of authorized management systems
Flag any external IP reaching camera management ports as suspicious in perimeter firewall and intrusion detection system rules

Monitoring Recommendations

Continuously monitor Video Surveillance and Internet of Things (IoT) network segments for outbound anomalies indicating a compromised camera
Track firmware version and configuration drift on Apeman devices to detect tampering after unauthorized access
Alert on new listeners or reverse connections from cameras to unfamiliar destinations

How to Mitigate CVE-2025-11852

Immediate Actions Required

Remove Apeman ID71 cameras from any internet-exposed interface and block inbound access to camera management ports at the perimeter
Place affected cameras on an isolated Virtual Local Area Network (VLAN) with strict access control lists restricting who can reach /onvif/device_service
Inventory all Apeman devices in the environment and evaluate replacement given the vendor's lack of response to disclosure

Patch Information

No vendor patch is available. According to the CVE record, the vendor was contacted early about this disclosure but did not respond. Organizations should assume the vulnerability will remain unfixed and plan compensating controls or device replacement accordingly.

Workarounds

Enforce network-level authentication using an upstream reverse proxy that requires credentials before forwarding to /onvif/device_service
Restrict ONVIF traffic to a dedicated management workstation using host-based firewall rules or switch access control lists
Disable ONVIF on the device if the configuration interface allows it, and use only local Real Time Streaming Protocol (RTSP) capture over an isolated network
Monitor camera traffic with a network intrusion detection system tuned to flag unauthenticated ONVIF SOAP calls

bash

# Example: block external access to camera ONVIF endpoint at the firewall
# Replace CAMERA_SUBNET and MGMT_HOST with values for your environment
iptables -A FORWARD -p tcp -d CAMERA_SUBNET --dport 80 -j DROP
iptables -I FORWARD -p tcp -s MGMT_HOST -d CAMERA_SUBNET --dport 80 -j ACCEPT
