Remote Code Execution in Lorex 2K Indoor Wi-Fi Security Camera

Executive Summary

CVE-2026-15680 is a format string vulnerability in the Lorex 2K Indoor Wi-Fi Security Camera. The vulnerability exists in the 'sonia' binary, which improperly handles JSON requests by failing to validate user-supplied strings before using them as format specifiers.

A format string vulnerability occurs when an application passes untrusted input directly to a function that interprets format specifiers (e.g., printf in C). Attackers can exploit this to read or write arbitrary memory, leading to remote code execution (RCE). In this case, the flaw allows network-adjacent attackers to execute arbitrary code on the affected device without requiring authentication.

The vulnerability is classified as a 'Remote Code Execution' (RCE) issue, meaning successful exploitation could give attackers full control over the device with root privileges.

Impact Analysis

If you own or use a Lorex 2K Indoor Wi-Fi Security Camera affected by this vulnerability, the impact could be severe due to the following risks:

• Unauthorized Access: Attackers on the same network (network-adjacent) can exploit this flaw without needing credentials, potentially gaining full control over the camera.
• Remote Code Execution (RCE): Attackers could execute arbitrary code on the device, allowing them to manipulate camera functionality, disable security features, or use the device as a pivot point to attack other systems on your network.
• Privacy Violations: Since the camera is a security device, attackers could access live feeds, recorded footage, or other sensitive data stored or transmitted by the camera.
• Network Compromise: The camera could be used as an entry point to launch further attacks against other devices connected to your network, such as computers, smartphones, or IoT devices.

Given the CVSS base score of 7.5 (High), this vulnerability poses a significant risk, particularly in environments where the camera is used for security or monitoring purposes.

Compliance Impact

This vulnerability could have serious implications for compliance with data protection and privacy regulations, depending on how the affected camera is used:

• GDPR (General Data Protection Regulation): If the camera is used in an environment where it captures or processes personal data of EU citizens (e.g., in a business or public space), unauthorized access to camera feeds or recordings could constitute a data breach. GDPR requires organizations to implement appropriate security measures to protect personal data, and failure to patch or mitigate this vulnerability could lead to non-compliance, fines, or legal action.
• HIPAA (Health Insurance Portability and Accountability Act): In healthcare settings, if the camera is used to monitor areas where protected health information (PHI) is accessible (e.g., patient rooms, medical storage areas), exploitation of this vulnerability could result in unauthorized access to PHI. This would violate HIPAA's Security Rule, which mandates safeguards to protect electronic PHI (ePHI).
• Other Standards (e.g., PCI DSS, NIST): If the camera is part of a broader security infrastructure (e.g., monitoring payment terminals or sensitive areas), exploitation could lead to non-compliance with standards like PCI DSS (for payment security) or NIST guidelines (for federal or critical infrastructure security).

Organizations using the affected camera should assess their risk exposure, apply patches or mitigations promptly, and document their response to demonstrate compliance with relevant regulations.

Mitigation Strategies

Based on the provided context, here are immediate mitigation steps for CVE-2026-15680:

• Isolate affected Lorex 2K Indoor Wi-Fi Security Cameras from the network to prevent potential exploitation by network-adjacent attackers.
• Check for firmware updates from the vendor (Lorex) and apply them as soon as they become available, as they may contain patches for this vulnerability.
• Restrict network access to the cameras using firewalls or VLANs to limit exposure to only trusted devices or networks.
• Monitor network traffic for unusual activity targeting the cameras, such as malformed JSON requests or unexpected format strings in network payloads.
• Consider disabling the cameras temporarily if they are not critical to operations until a patch is applied.
