CVE-2024-54013: Web Server Auth Bypass Vulnerability

CVE-2024-54013 Overview

CVE-2024-54013 is a high-severity authentication bypass vulnerability affecting Hanwha Vision camera web server components. Penetration testing engineers at Amazon discovered a security flaw related to request handling in the web server component that could, under certain conditions, lead to unintended access to protected functions. This vulnerability is classified under CWE-306 (Missing Authentication for Critical Function), indicating that the affected system fails to properly authenticate users before granting access to sensitive functionality.

Critical Impact

Attackers on an adjacent network can bypass authentication controls to gain unauthorized access to protected camera functions, potentially compromising confidentiality, integrity, and availability of affected devices.

Technical Details for CVE-2024-54013

Vulnerability Analysis

This vulnerability stems from improper request handling within the camera's web server component. The flaw allows attackers to bypass authentication mechanisms and access protected functions that should require proper authorization. The adjacent network attack vector means that an attacker must have access to the same network segment as the vulnerable device, which is common in scenarios involving IoT devices like security cameras deployed on local networks.

The vulnerability does not require any user interaction or prior privileges to exploit, making it particularly dangerous in environments where cameras are accessible from shared network segments. Successful exploitation could allow complete compromise of affected camera devices, enabling attackers to view camera feeds, modify settings, or disable security monitoring capabilities.

Root Cause

The root cause of this vulnerability is CWE-306: Missing Authentication for Critical Function. The web server component fails to enforce proper authentication checks on certain requests, allowing unauthenticated users to access functionality that should be restricted to authorized administrators. This design flaw in the request handling logic enables attackers to craft requests that bypass the intended authentication flow.

Attack Vector

The attack vector requires adjacent network access, meaning the attacker must be positioned on the same local network or network segment as the vulnerable Hanwha Vision camera. From this position, an attacker can send specially crafted HTTP requests to the camera's web server that exploit the missing authentication checks.

The attack flow involves identifying exposed camera devices on the network, sending unauthenticated requests to protected endpoints, and gaining access to administrative functions or sensitive data without providing valid credentials. Since no user interaction is required and the complexity is low, this attack can be easily automated against multiple vulnerable devices on a network.

Detection Methods for CVE-2024-54013

Indicators of Compromise

• Unusual HTTP requests to camera web interfaces from unexpected network hosts
• Access to administrative endpoints without corresponding authentication events in logs
• Unauthorized configuration changes on Hanwha Vision camera devices
• Anomalous network traffic patterns targeting camera management ports

Detection Strategies

• Monitor network traffic for unauthenticated requests to camera web server endpoints
• Implement network segmentation alerts for cross-segment traffic to IoT devices
• Deploy intrusion detection rules to identify authentication bypass attempts
• Review camera access logs for requests that bypass normal authentication flows

Monitoring Recommendations

• Enable verbose logging on Hanwha Vision camera devices to capture all web server requests
• Implement network-level monitoring for traffic to camera management interfaces
• Deploy SIEM rules to correlate failed authentication attempts with subsequent successful access
• Monitor for unauthorized changes to camera configurations or settings

How to Mitigate CVE-2024-54013

Immediate Actions Required

• Apply the patch firmware released by Hanwha Vision as soon as possible
• Isolate vulnerable cameras on separate network segments with strict access controls
• Review camera configurations for unauthorized changes
• Implement network access controls to limit which hosts can communicate with camera devices

Patch Information

Hanwha Vision has released patch firmware to address this vulnerability. Organizations should consult the Hanwha Vision CVE-2024-5401 Report for detailed patch information, affected product versions, and specific firmware update instructions.

Workarounds

• Implement strict network segmentation to isolate cameras from untrusted network segments
• Deploy firewall rules to restrict access to camera web interfaces to authorized management hosts only
• Enable VPN or other secure access methods for remote camera management
• Disable unnecessary web server features on affected devices until patching is complete

# Example network segmentation firewall rule (adapt to your environment)
# Restrict camera subnet access to management VLAN only
