CVE-2023-51127: n/a in n/a
FLIR AX8 thermal sensor cameras up to and including 1.46.16 are vulnerable to Directory Traversal due to improper access restriction. This vulnerability allows an unauthenticated, remote attacker to obtain arbitrary sensitive file contents by uploading a specially crafted symbolic link file.
AI Analysis
Technical Summary
CVE-2023-51127 is a high-severity directory traversal vulnerability affecting FLIR AX8 thermal sensor cameras up to and including firmware version 1.46.16. The root cause is improper access restriction that allows an unauthenticated remote attacker to exploit the device by uploading a specially crafted symbolic link file. This symbolic link can be used to traverse directories on the device's filesystem, enabling the attacker to access arbitrary sensitive files that should otherwise be protected. Since no authentication or user interaction is required, the attack surface is broad, and exploitation can be performed remotely over the network. The vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), indicating a failure in input validation or access control mechanisms related to file paths. The CVSS v3.1 base score is 7.5, reflecting high impact on confidentiality (full disclosure of sensitive files), no impact on integrity or availability, and ease of exploitation due to lack of authentication and low attack complexity. No known exploits are currently reported in the wild, and no official patches or mitigation links have been provided as of the publication date (January 10, 2024). The FLIR AX8 is commonly used in industrial, commercial, and critical infrastructure environments for thermal monitoring and safety, making this vulnerability particularly concerning for organizations relying on these devices for operational security and safety monitoring.
Potential Impact
For European organizations, the impact of CVE-2023-51127 can be significant, especially in sectors such as manufacturing, energy, utilities, and critical infrastructure where FLIR AX8 thermal cameras are deployed for safety and operational monitoring. Unauthorized access to sensitive files could lead to exposure of configuration files, credentials, or operational data, potentially enabling further attacks or espionage. Confidentiality breaches could compromise operational security and privacy, and attackers could leverage the information gained to disrupt processes or gain deeper network access. Since the vulnerability does not affect integrity or availability directly, immediate operational disruption is less likely, but the information disclosure risk is substantial. European organizations subject to strict data protection regulations (e.g., GDPR) may face compliance risks if sensitive personal or operational data is exposed. Additionally, the lack of authentication requirement increases the risk of automated scanning and exploitation attempts, which could be leveraged by cybercriminals or state-sponsored actors targeting European critical infrastructure or industrial sectors.
Mitigation Recommendations
1. Immediate network segmentation: Isolate FLIR AX8 devices from general network access, restricting communication to trusted management networks only. 2. Implement strict firewall rules to block unauthorized inbound traffic to the devices, especially from untrusted or external networks. 3. Monitor network traffic for unusual upload attempts or symbolic link file transfers targeting these devices. 4. Apply vendor patches or firmware updates as soon as they become available; actively monitor FLIR security advisories for updates addressing CVE-2023-51127. 5. If patches are unavailable, consider temporary compensating controls such as disabling remote upload features or restricting file upload capabilities. 6. Conduct regular security audits and vulnerability scans focusing on IoT and industrial control devices, including FLIR AX8 cameras. 7. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect directory traversal attempts and symbolic link exploitation patterns. 8. Maintain an inventory of all FLIR AX8 devices and ensure they are included in incident response and patch management processes. 9. Educate operational technology (OT) and security teams about this vulnerability and the risks of unauthenticated access to IoT devices.
