CVE-2024-3013 identifies an improper authorization vulnerability in Teledyne FLIR AX8 thermal camera devices running firmware versions up to 1.46.16. The vulnerability resides in an unspecified function within the user registration component, specifically the /tools/test_login.php?action=register endpoint. This flaw allows remote attackers to manipulate the registration process to bypass authorization checks without requiring authentication or user interaction. The consequence is that an attacker could gain unauthorized access to the device's internal web interface, potentially enabling them to alter configurations, access sensitive data, or disrupt device operations. The vulnerability is remotely exploitable over the network with low attack complexity and no privileges required, although it requires some level of local privileges (PR:L) per the CVSS vector. The impact on confidentiality, integrity, and availability is limited but non-negligible, as unauthorized access could lead to partial compromise of device functions. The vendor has addressed the issue by refactoring the internal web site and releasing firmware version 1.49.16, which fully mitigates the vulnerability. While no active exploits have been reported in the wild, proof-of-concept exploit code is publicly available, increasing the risk of exploitation. The affected product, FLIR AX8, is widely used in industrial monitoring, energy management, and critical infrastructure environments, where unauthorized access could have operational consequences.

For European organizations, the improper authorization vulnerability in FLIR AX8 devices poses risks primarily to operational technology and industrial control environments. Unauthorized access to these thermal cameras could allow attackers to manipulate device settings, disable monitoring, or exfiltrate sensitive thermal imaging data used for safety and operational decisions. This could lead to reduced situational awareness, potential safety hazards, and disruption of critical infrastructure monitoring. Organizations in sectors such as energy, manufacturing, transportation, and utilities that deploy FLIR AX8 devices for condition monitoring and security surveillance are particularly vulnerable. The medium severity rating reflects a moderate risk, but the potential for lateral movement or escalation within a network increases the threat. Additionally, the remote exploitability without user interaction heightens the urgency for patching. Failure to remediate could result in compliance issues with European cybersecurity regulations, such as NIS2, which mandate protection of critical infrastructure. The impact is compounded in environments where these devices are integrated into broader security or operational networks without adequate segmentation.

European organizations should immediately upgrade all FLIR AX8 devices to firmware version 1.49.16 or later to remediate CVE-2024-3013. Beyond patching, organizations should implement network segmentation to isolate FLIR AX8 devices from general IT networks, limiting exposure to potential attackers. Access controls should be tightened, ensuring that only authorized personnel can reach the device management interfaces, preferably via VPN or secure management networks. Monitoring and logging of access to these devices should be enabled and regularly reviewed for suspicious activity. If upgrading is temporarily not possible, organizations should restrict network access to the affected endpoints, using firewalls or access control lists to block unauthorized connections to the /tools/test_login.php endpoint. Regular vulnerability scanning and asset inventory should be conducted to identify all affected devices. Finally, organizations should review and update incident response plans to include scenarios involving operational technology device compromise.
