CVE-2025-10538: LG Innotek Camera Auth Bypass Flaw

CVE-2025-10538 Overview

CVE-2025-10538 is an authentication bypass vulnerability affecting LG Innotek network camera models LND7210 and LNV7210R. The flaw allows a remote, unauthenticated attacker to access camera information, including user account data, without supplying valid credentials. The vulnerability is classified under CWE-288: Authentication Bypass Using an Alternate Path or Channel. CISA published advisory ICSA-25-273-07 covering this issue in the industrial control systems ecosystem, where these cameras are commonly deployed for physical security monitoring.

Critical Impact

Remote attackers can bypass authentication over the network to extract sensitive camera information and user account data without any user interaction or prior privileges.

Technical Details for CVE-2025-10538

Vulnerability Analysis

The vulnerability resides in the authentication layer of the LG Innotek LND7210 and LNV7210R camera firmware. According to the published advisory, an attacker can interact with the camera over the network and obtain protected information without completing the authentication workflow. The exposed data includes user account information, which can be leveraged for follow-on attacks against the camera or connected systems.

The issue maps to [CWE-288], which describes scenarios where a product provides a path that does not enforce the standard authentication routine. In practice, this means a specific request path, parameter, or interface state grants access that should require valid credentials.

Root Cause

The root cause is improper enforcement of authentication on one or more endpoints exposed by the camera's management interface. The camera firmware fails to validate session state or credentials before returning sensitive responses. Because the cameras are network-accessible, this design flaw is reachable directly from any host that can connect to the device.

Attack Vector

The attack vector is network-based and requires no privileges or user interaction. An attacker sends crafted requests to the exposed camera service and receives configuration or account data in response. Disclosed user account information can enable credential reuse attacks, lateral movement into video management systems, or persistent unauthorized surveillance access.

No verified public proof-of-concept code is available for this vulnerability. Technical details are documented in the CISA ICS Advisory ICSA-25-273-07.

Detection Methods for CVE-2025-10538

Indicators of Compromise

• Unexpected HTTP or RTSP requests to camera management endpoints from external or unauthorized internal hosts
• Access log entries showing successful responses to requests that lack valid session tokens or authentication headers
• Outbound connections from camera IP addresses to unfamiliar destinations following reconnaissance activity

Detection Strategies

• Inspect network traffic to LG Innotek cameras for requests that return account or configuration data without a preceding authentication exchange
• Compare camera access logs against an allowlist of approved management hosts and flag deviations
• Monitor for enumeration patterns such as repeated requests to administrative URIs from a single source

Monitoring Recommendations

• Forward camera and network device logs to a centralized analytics platform for correlation against asset inventories
• Alert on any direct internet exposure of LND7210 or LNV7210R management ports identified via external attack surface scanning
• Track firmware versions across the camera fleet and alert when devices fall behind the vendor's fixed release

How to Mitigate CVE-2025-10538

Immediate Actions Required

• Identify all LG Innotek LND7210 and LNV7210R cameras in the environment and inventory their firmware versions
• Remove direct internet exposure of camera management interfaces and place devices behind firewalls or VPN gateways
• Rotate any user account credentials configured on affected cameras to limit reuse if data was already exfiltrated

Patch Information

Refer to the CISA ICS Advisory ICSA-25-273-07 for vendor-supplied remediation guidance and any firmware updates released by LG Innotek. Apply the recommended firmware version across all affected devices once available, and validate that authentication is enforced on all management endpoints after the update.

Workarounds

• Segment cameras onto a dedicated VLAN with strict ACLs that only permit traffic from authorized video management servers
• Block inbound access to camera management ports at the perimeter firewall and require VPN access for administration
• Disable any unused network services on the cameras to reduce the exposed attack surface until firmware is patched

# Example firewall rule restricting camera management access to a trusted subnet
iptables -A FORWARD -s 10.10.20.0/24 -d <camera_ip> -p tcp --dport 80 -j ACCEPT
iptables -A FORWARD -d <camera_ip> -p tcp --dport 80 -j DROP
iptables -A FORWARD -d <camera_ip> -p tcp --dport 443 -j DROP
