CVE-2024-2863 Scanner

The LG LED Assistant is a software tool used globally by businesses and signage professionals to manage and control digital displays effectively. Designed by LG Electronics, it facilitates the seamless operation and customization of LED displays for diverse commercial environments, including retail spaces, corporate offices, and public institutions. The application helps in configuring various display parameters such as brightness, color calibration, and scheduling content display to enhance viewer engagement. By providing an easy-to-use interface, LG LED Assistant supports users in optimizing the visual performance of their LED installations. Its deployment in visual marketing and communication strategies makes it a crucial asset for businesses aiming to capture attention and convey messages effectively.

The path traversal vulnerability within LG LED Assistant poses significant security risks. Unauthenticated remote attackers can exploit this flaw to upload arbitrary files anywhere on the disk where the application is installed. This vulnerability arises from improper input validation in the endpoint handler for /api/thumbnail. Attackers leverage this weakness to traverse directories in the file system, potentially overwriting critical files and gaining unauthorized system access. Such security breaches could lead to data manipulation, service disruptions, and unauthorized backdoor installations. This highlights a major security oversight in the application's handling of file paths and permissions.

In technical terms, the vulnerability exists in the endpoint handler for /api/thumbnail within Common.js. Attackers exploit it by manipulating the 'fileName' parameter to include path traversal sequences (e.g., ../../), allowing them to define arbitrary paths for file upload. By encoding malicious content into the 'fileStr' parameter, attackers can inject scripts or executable files into vulnerable systems. Successful exploitation is indicated by a success response with the status code 200 from the server. This vulnerability highlights the critical need for secure coding practices, including sanitizing user inputs and implementing strict file access controls, to protect against such attacks.

Exploiting this vulnerability can result in severe consequences, including unauthorized modification or destruction of data, installation of malicious software, and potential system compromise. It may allow attackers to execute arbitrary code, breach sensitive information, and disrupt services, leading to financial loss and reputational damage for affected organizations. The vulnerability's high severity rating underscores the urgency of implementing robust security measures to mitigate potential exploitation. Regular security audits and timely patching are vital to maintaining system integrity and safeguarding valuable assets against such threats.
