CVE-2025-7742 is a high-severity authentication bypass vulnerability identified in the LG Innotek camera model LNV5110R. The vulnerability stems from improper authentication controls that allow an attacker to upload an HTTP POST request directly to the device's non-volatile storage without proper verification. This bypass of authentication mechanisms enables remote code execution (RCE) on the affected device, granting the attacker the ability to execute arbitrary commands with administrator-level privileges. The vulnerability is classified under CWE-288, which pertains to authentication bypass using an alternate path or channel. The CVSS 4.0 base score of 8.3 reflects the critical nature of this flaw, with an attack vector that is network-based (AV:N), requiring high attack complexity (AC:H), no privileges (PR:N), and no user interaction (UI:N). However, the vulnerability impacts the confidentiality, integrity, and availability of the device with high confidentiality impact (VC:H) and low integrity and availability impacts (VI:L, VA:L). The vulnerability affects all firmware versions of the LNV5110R camera model, and no patches or mitigations have been published yet. Although no known exploits are currently observed in the wild, the potential for exploitation is significant given the device's network exposure and administrative access compromise. The vulnerability allows attackers to potentially take full control of the camera, which could be leveraged for surveillance, lateral movement within networks, or as a foothold for further attacks.

For European organizations, the impact of this vulnerability is substantial, especially for entities relying on LG Innotek LNV5110R cameras for security, surveillance, or operational monitoring. Compromise of these devices could lead to unauthorized surveillance, leakage of sensitive visual data, and disruption of security operations. Furthermore, since the attacker gains administrator-level control, the device could be used as a pivot point to infiltrate internal networks, potentially compromising other critical systems. This risk is heightened in sectors such as government, critical infrastructure, manufacturing, and corporate environments where such cameras are deployed. The breach of confidentiality could violate GDPR requirements, leading to regulatory penalties and reputational damage. Additionally, the lack of available patches increases the window of exposure, necessitating immediate risk mitigation. The high attack complexity somewhat limits mass exploitation but does not eliminate targeted attacks, especially by advanced threat actors.

Given the absence of official patches, European organizations should implement several specific mitigations: 1) Network Segmentation: Isolate the affected cameras on dedicated VLANs or network segments with strict access controls to limit exposure. 2) Access Restrictions: Employ firewall rules to restrict inbound HTTP POST requests to the cameras only from trusted management IP addresses. 3) Monitoring and Logging: Enable detailed logging of all HTTP requests to the cameras and monitor for unusual POST requests or unauthorized access attempts. 4) Firmware Auditing: Regularly check for firmware updates from LG Innotek and apply patches immediately upon release. 5) Device Replacement: For high-security environments, consider replacing vulnerable camera models with devices from vendors with a stronger security track record. 6) Incident Response Preparedness: Develop and test incident response plans specific to IoT device compromises, including camera devices. 7) Disable Unused Services: Where possible, disable HTTP services or restrict management interfaces to secure protocols (e.g., HTTPS with strong authentication). 8) Vendor Engagement: Engage with LG Innotek for timelines on patch releases and request security advisories.
