CVE-2025-7742 is a high-severity authentication bypass vulnerability affecting all firmware versions of 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 device, granting the attacker the ability to execute arbitrary commands with administrator-level privileges. The root cause is classified under CWE-288, which involves authentication bypass using an alternate path or channel, indicating that the attacker exploits an unintended access vector to circumvent normal authentication checks. The CVSS 4.0 base score of 8.3 reflects the critical nature of this vulnerability, with network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality (VC:H), with low impacts on integrity and availability. Although no known exploits are currently reported in the wild, the potential for exploitation is significant given the device's exposure on networks and the administrative control gained upon successful exploitation. The lack of available patches at the time of publication increases the urgency for mitigation and risk management.

For European organizations, the impact of this vulnerability can be substantial, especially for entities relying on LG Innotek LNV5110R cameras for security surveillance, access control, or operational monitoring. Successful exploitation could lead to unauthorized access to sensitive video feeds, compromising privacy and potentially violating GDPR regulations concerning personal data protection. Furthermore, attackers gaining administrator-level control could pivot within the network, deploy malware, or disrupt operations, affecting business continuity and safety. Critical infrastructure sectors such as transportation, energy, and government facilities that use these cameras for monitoring could face espionage, sabotage, or data breaches. The high confidentiality impact is particularly concerning in environments where video data contains sensitive or personally identifiable information. Additionally, the remote code execution capability could be leveraged to create persistent backdoors or launch further attacks within the network, amplifying the threat landscape for European organizations.

Given the absence of official patches, European organizations should implement immediate compensating controls. These include isolating affected cameras on segmented, monitored network zones with strict firewall rules limiting inbound and outbound traffic to only trusted management hosts. Employ network intrusion detection systems (NIDS) to monitor for anomalous HTTP POST requests or unusual traffic patterns targeting the cameras. Disable remote management interfaces if not strictly necessary or restrict access via VPNs with multi-factor authentication. Regularly audit device firmware versions and monitor vendor communications for patch releases. Where possible, replace vulnerable devices with models that have verified secure firmware. Additionally, implement strict physical security controls to prevent unauthorized local access to devices. Organizations should also conduct penetration testing and vulnerability assessments focusing on IoT and camera devices to identify and remediate similar weaknesses proactively.
