A significant security flaw has been identified in LG Innotek’s LNV5110R camera model, potentially allowing cybercriminals to gain full administrative control over affected devices. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory on July 24, 2025, highlighting the remotely exploitable nature of this vulnerability, which impacts all versions of the camera model globally.
Key Takeaways:
1. Critical Vulnerability Identified: The LG Innotek LNV5110R cameras possess a severe security flaw that permits remote administrative takeover.
2. No Security Patches Available: As the product has reached its end-of-life status, no security patches will be provided to address this issue.
3. Recommended Protective Measures: Users are advised to implement network isolation and utilize firewalls as primary defense mechanisms.
Authentication Bypass Vulnerability (CVE-2025-7742):
The vulnerability, designated as CVE-2025-7742, arises from an authentication bypass using an alternate path or channel (CWE-288). Security researcher Souvik Kandar discovered that malicious actors can exploit this flaw by uploading specially crafted HTTP POST requests to the device’s non-volatile storage. This weakness allows attackers to circumvent standard security controls and execute arbitrary commands with administrator-level privileges.
The vulnerability has been assigned a CVSS v3.1 base score of 7.0, indicating high network accessibility but also high attack complexity. Under the newer CVSS v4.0 scoring system, the flaw receives a more severe base score of 8.3, emphasizing the significant risk to confidentiality.
Successful exploitation of this vulnerability enables remote code execution (RCE), allowing attackers to run arbitrary commands on target devices at the administrator privilege level. This level of access could enable cybercriminals to manipulate camera feeds, access sensitive surveillance data, or use compromised devices as pivot points for broader network attacks.
The vulnerability particularly threatens commercial facilities and critical infrastructure sectors where these cameras are commonly deployed. The flaw’s network-accessible nature means attackers can potentially exploit it from anywhere on the internet without requiring physical access to the devices. However, CISA notes that the vulnerability has high attack complexity, and no known public exploitation targeting this specific flaw has been reported at this time.
Risk Factors:
– Affected Products: LG Innotek Camera Model LNV5110R (All versions)
– Impact:
– Remote code execution
– Administrative access takeover
– Exploit Prerequisites:
– Network access to device
– High technical complexity
– No user interaction required
– No prior authentication needed
– CVSS 3.1 Score: 7.0 (High)
End-of-Life Status:
LG Innotek has confirmed that the LNV5110R model is an end-of-life product that will not receive security patches. Users must rely on defensive measures to minimize exposure, including isolating devices from internet access and implementing network segmentation behind firewalls.
CISA recommends implementing defense-in-depth strategies, using Virtual Private Networks (VPNs) for remote access, and ensuring control system networks remain isolated from business networks. Organizations should perform proper impact analysis and risk assessment before deploying defensive measures.
Broader Implications:
The situation with the LNV5110R cameras underscores a broader trend in the Internet of Things (IoT) and surveillance hardware sectors. Devices often outlast their vendor support windows, resulting in a growing number of zombie devices susceptible to attacks. Security researchers have noted that firmware lifecycles regularly lag behind the physical longevity of these products, especially in sectors where upgrade cycles are infrequent or costly.
Mitigation Measures:
Although no patches are available, some risk reduction techniques are recommended:
1. Network Segmentation: Place all control devices, including cameras, behind strict network boundaries (segregated VLANs or physical firewalls). They should be inaccessible from public internet endpoints wherever possible.
2. Minimize Exposure: Remove direct remote access capabilities, including disabling port forwarding and UPnP. If remote administration is necessary, restrict it via site-to-site VPNs and robust access controls.
3. Monitor and Log: Employ continuous monitoring on both application and network layers to detect unusual traffic destined for camera endpoints. Log all access attempts and integrate with existing Security Information and Event Management (SIEM) solutions.
4. Replace Vulnerable Devices: Create and enact a phased plan to transition away from unsupported cameras. While upfront costs may be significant, the potential for costly breaches or regulatory penalties is often far higher.
5. Vendor Guidance: Review the LG Security Center for late-breaking advisories and best practices, although remediation options are now limited.
It’s vital to recognize, as CISA advises, that even VPNs and traditional perimeter defenses can themselves be vulnerable if not properly maintained and updated. Security should be approached as a holistic, defense-in-depth regimen.
Conclusion:
The discovery of the CVE-2025-7742 vulnerability in LG Innotek’s LNV5110R cameras highlights the critical importance of proactive cybersecurity measures, especially for end-of-life products. Organizations must remain vigilant, implementing robust defensive strategies to protect their networks and sensitive data from potential exploitation.
